General information During operation, drive power converters may have, depending on their protection class, live, bare, moving or rotating parts or hot surfaces. Unauthorised removal of covers, improper use, incorrect installation or operation leads to the risk of serious personal injury or material damage. Further information can be found in this documentation. All transportation, installation and initialisation and maintenance work must be carried out by qualified personnel (comply with IEC 364, CENELEC HD 384, DIN VDE 0100, IEC 664 and DIN VDE 0110, and national accident prevention regulations). For the purposes of these basic safety instructions, qualified personnel are persons who are familiar with the erection, installation, initialisation and operation of this product and who have the relevant qualifications for their work. 2. Proper use Drive power converters are components intended for installation in electrical systems or machines. When being installed in machines, the drive power converter cannot be initialised (i.e. implementation of the proper use) until it has been ensured that the machine meets the provisions of the EC directive 89/392/EEC (machine directive); EN must also be complied with. Initialisation (i.e. implementation of the proper use) is only permitted when the EMC directive (89/336/EEC) is complied with. The drive power converters meet the requirements of the low voltage directive 73/23/EEC. The harmonised standards in pren 50178/DIN VDE 0160, together with EN /VDE 0660 Part 500 and EN 60146/VDE 0558 were applied for the drive power converter. Technical data and information for connection conditions can be found on the rating plate and in the documentation, and must be complied with. 3. Transport, storage Information regarding transport, storage and correct handling must be complied with. 4. Erection The erection and cooling of the equipment must be implemented as per the regulations in the corresponding documentation. The drive power converter must be protected against impermissible loads. During transport and handling in particular, components must not be deformed and/or insulation distances must not be changed. Touching of electronic components and contacts must be avoided. Drive power converters have electrostatically sensitive components that can be easily damaged by incorrect handling. Electrical components must not be mechanically damaged or destroyed (this may cause a health hazard!). 5. Electrical connections When working on live drive power converters, the applicable national accident prevention regulations must be complied with (e.g. VBG 4). The electrical installation must be implemented as per the applicable regulations (e.g. cable cross-section, fuses, ground lead connections). Further information is contained in the documentation. Information about EMC-compliant installation such as shielding, earthing, location of filters and installation of cables can be found in the drive power converter documentation. These instructions must be complied with even with CE marked drive power converters. Compliance with the limit values specified in the EMC regulations is the responsibility of the manufacturer of the system or machine. 6. Operation Systems where drive power converters are installed must be equipped, where necessary, with additional monitoring and protective equipment as per the applicable safety requirements, e.g. legislation concerning technical equipment, accident prevention regulations, etc. Modifications to the drive power converter using the operating software are permitted. After the drive power converter is disconnected from the power supply, live equipment components and power connections should not be touched immediately because of possible charged capacitors. Comply with the applicable information signs located on the drive power converter. All covers must be kept closed during operation. 7.

6 NORDAC SK 500E / 520E Handbook 1 General information The NORDAC SK 500E / 520E series is based on the tried and tested NORD platform. The distinguishing features of this equipment are the compact design and excellent control characteristics. These devices are provided with sensorless vector current control system which constantly ensures an optimised voltage-to-frequency ratio based on the simulated operation of a three-phase asynchronous motor. This has the following significance for the drive: the highest level of start-up and overload torque at constant speed. The modular technology boxes allow this device series to be adapted to individual demands. Owing to the huge variety of setting options these inverters are capable of controlling any three-phase motor. The output ranges from 0.25kW to 7.5kW with integrated line filter. The overload capacity of this equipment is for 3.5 seconds at 200% and for 60 seconds at 150%. The present manual applies to device software V1.3 R1 (P707) of the SK 500E / 520E. Other frequency inverter software versions may result in differences.

8 NORDAC SK 500E / 520E Handbook 1.4 Safety and installation information NORDAC SK 500E / 520E frequency inverters are equipment for use in industrial high voltage systems and are operated at voltages that could lead to severe injuries or death if they are touched. Installation and other work is only permitted by qualified electricians and when the device is disconnected. The manual must always be available for these persons and must be complied with. Local regulations for the installation of electrical equipment as well as for accident prevention are to be observed. The equipment continues to carry hazardous voltages for up to 5 minutes after being switched off at the mains. Mains impedance must be at least 100 μh per circuit in case of single-phase operation (230 V). Otherwise, a line choke must be connected in series. To ensure safe separation from mains, all power cable poles to the frequency inverter must be separated. Even during motor standstill (e.g. caused by a release block, blocked drive or output terminal short circuit), the line connection terminals, motor terminals and braking resistor terminals may still conduct hazardous voltages. A motor standstill is not identical to galvanic isolation from the mains. Caution: Even parts of the control card and, in particular, the connection plug for the removable technology units can conduct hazardous voltages. The control terminals are mains voltage free. Caution: Under certain settings the inverter can start automatically after the mains are switched on. The inverter is only intended for permanent connection and may not be operated without effective earthing connections that comply with local regulations for high leakage currents (> 3.5mA). VDE 0160 requires the installation of a second earthing conductor or an earthing conductor crosssection of at least 10 mm 2. Normal FI-circuit breakers are not suitable as the sole protection in three-phase frequency inverters when local regulations do not permit a possible DC proportion in the fault current. The standard FI circuit breaker must comply with the new design as per VDE NORDAC SK 500E / 520E frequency inverters are maintenance-free when used correctly. The cooling surfaces must be regularly cleaned with compressed air if the ambient air is dusty. ATTENTION The heat sink and all other metal parts can heat up to temperatures exceeding 70 C. Install the unit only with sufficient distance to adjacent components. Before working on components allow for a sufficient cooling period. WARNING DANGER TO LIFE! The power unit can continue to carry voltages for up to 5 minutes after being switched off at the mains. Inverter terminals, motor cables and motor terminals may carry voltage! Touching open or free terminals, cables and equipment components can lead to severe injury or death! 8 Subject to technical changes BU 0500 GB

11 2 Assembly and installation 2 Assembly and Installation 2.1 Installation NORDAC SK 500E / 520E frequency inverters are available in various sizes depending on the output. Heed a suitable installation position. The equipment requires sufficient ventilation to protect against overheating. Guide values apply here for the space above and below the inverter to neighbouring components that could restrict the air flow. (above > 100 mm, below > 100 mm) Mounting can be adjacent. The installation position must be vertical. Make sure that the heat sink fins at the rear of the device are on a level surface to ensure proper cooling. 100mm 100mm Warm air must be able to escape above the equipment! If several frequency inverters are arranged above each other, ensure that the air entry temperature limit is not exceeded. (see also chap. 7, technical data). In this case, it is recommended that any obstacles (e.g. a cable duct) are mounted between the inverters so that the direct air flow (rising warm air) is interrupted. Heat loss: Ensure sufficient ventilation when the devices are installed in a control cabinet. The lost heat is approximately 5% (depending on the device size and configuration) of the rated frequency inverter output. BU 0500 GB Subject to technical changes 11

13 2 Assembly and installation 2.3 SK 500E / 520E wall mount bracket The SK 500E / 520E comes with 2 suitable brackets for panel mounting. These can be pushed into the heat sink at the device rear as shown in the illustration. No accessories are needed to do this! As an alternative you can also push the wall mount brackets laterally into the heat sink in order to minimise the required control cabinet depth if necessary. Make sure to always cover the heat sink rear with a level surface and to install the device in a vertical position. This will result in optimum convection and ensure trouble-free operation.

14 NORDAC SK 500E / 520E Handbook 2.4 EMC kit To comply with the conducted radio interference suppression level B1 (see chapt. 8.4), the optional EMC kit must be implemented. It comprises a shielding bracket, a clamp and a toroidal ferrite. Fasten the shielding bracket at the lower edge (below the U-V-W terminals) with the two housing screws. The screen clamp serves to connect a large motor cable shielding area to the shielding bracket. Simply route the 3 lines for the motor phases (U-V-W) through the toroidal ferrite (without PE!). Do this as close as possible to the terminals without shielding.

15 2 Assembly and installation 2.5 Brake resistor (BR) When dynamically braking a 3 phase motor (reducing the frequency) electrical energy is fed back into the inverter. To avoid an overvoltage shutdown of the inverter, an external brake resistor can be used. The internal brake chopper (an electronic switch) then pulses the intermediate circuit voltage onto the brake resistor (threshold level approx 420V/720V dc, according to supply voltage). The brake resistor transforms the surplus energy into heat. VORSICHT The heat sink and all other metal parts can heat up to temperatures exceeding 70 C. Install the unit only with sufficient distance to adjacent components. Before working on components allow for a sufficient cooling period. For inverter powers up to 2,2 kw a standard resistor for mounting directly below the inverter can be used (SK BR4-..., IP40). The resistor can be equipped with an optional thermal switch (Bimetalic, 180 C threshold) to report a possible overload. Fixing material is included in the lateral slot. The resistor and the optional thermal switch are connected to the inverter via wires. Approvals: UL, cul SK BR4-... size 1 SK BR4-... size 2 For inverter powers 3kW to 7.5kW stand alone chassis resistors are available (SK BR2-..., IP00). These resistors must be mounted in the switching cabinet close to the inverter. As standard a thermal switch is fitted to the resistor to report overloading. The resistor and the thermal switch are connected to the inverter via terminals and wires. Approvals: UL, cul SK BR2-... size 3 SK BR2-... size 4 BU 0500 GB Subject to technical changes 15

18 NORDAC SK 500E / 520E Handbook 2.6 Wiring guidelines The frequency inverter has been developed for use in an industrial environment. In this environment, high levels of electromagnetic interference can have an effect on the frequency inverter. In general, correct installation ensures safe and problem-free operation. In order to conform to the EMC guidelines, the following instructions should be adhered to. (1) Ensure that all equipment in the control cabinet or panel is securely earthed using short earthing cables that have large cross-sections and which are connected to a common earthing point or earthing bar. It is particularly important that each controller (e.g. automation device) is connected to the frequency inverter with a short, large profile cable and to the same grounding point as the inverter itself. Flat conductors (e.g. metal brackets) are preferable as they have low impedance at higher frequencies. (2) The PE lead of the motor controlled by the frequency inverter must be connected as directly as possible to the earth connection of the associated frequency inverter. The presence of a central earthing bar and the grouping together of all PE conductors to this bar normally ensures safe operation. (see also chap. 8.3/8.4 EMC) (3) Where possible, screened cables should be used for control signals. During installation, the shielding at the cable end should be carefully closed off, and care taken that the wires do not have long runs without shielding. The shields of analogue set point cables should only be earthed on one side on the frequency inverter. (4) The control cables must be kept distant from load cables by using separate cable ducts, etc. If cables cross, then an angle of 90 should be used where possible. (5) Ensure that the contactors in the cabinet are interference protected, either by RC circuits in the case of AC contactors or by free-wheeling diodes for DC contactors, for which the interference traps must be positioned on the contactor coils. Varistors for over-voltage limitation are also effective. This interference suppression is particularly important when the contactors are controlled by the relays of the frequency inverter. (6) Use screened or armoured cable for the load connections (motor cables) and earth the screening/armour at both ends. If possible, earthing should directly occur on the conductive control cabinet mounting plate of the EMC kit shielding bracket (chapt. 2.4). In addition, it is essential to use wiring suitable for EMC. (see also chap. 8.3/8.4 EMC) An optional output choke is available on request. The safety regulations must be complied with under all circumstances when installing frequency inverters! Note The control cables, line cables and motor cables must be laid separately. In no case should they be laid in the same protective pipes/installation ducts. The test equipment for high voltage insulations must not be used on cables that are connected to the frequency inverter. 18 Subject to technical changes BU 0500 GB

19 2 Assembly and installation 2.7 Electrical connections WARNING THIS EQUIPMENT MUST BE EARTHED. Safe operation of the equipment presupposes that qualified personnel mount and operate it in compliance with the instructions provided in this handbook. In particular, the general and regional mounting and safety regulations for work on high voltage systems (e.g. VDE) must be complied with as must the regulations concerning professional use of tools and the use of personal protection equipment. Dangerous voltages can be present at the line input and the motor connection terminals even when the frequency inverter is switched off. Always use insulated screwdrivers on these terminal fields. Ensure that the input voltage source is not live before setting up or changing connections to the unit. Make sure that the inverter and motor have the correct supply voltage set.

20 NORDAC SK 500E / 520E Handbook 2.8 Electrical power unit connections The line and brake resistor terminals are located on the frequency inverter top. The motor and brake resistor terminals are located on the frequency inverter bottom. The control terminals can be reached from the frequency inverter front. To do so, push the terminal cover (underneath the TU slot) down and remove it if necessary. The terminals are now accessible. X1 - PE L3 L2 L1 X L1 / L L2 / N L3 / - PE Heed the following before connecting the device: 1. Ensure that the electrical supply is of the correct voltage and is suitable for the current required (see Chapter 7, Technical data) 2. Ensure that suitable circuit breakers with the nominal current range are inserted between the electrical supply and the frequency inverter. 3. Connect the line voltage directly to the line terminals L 1 -L 2 /N-L 3 -PE (depending on the device). 4. A four core shielded cable must be used to connect the motor. The cable must be connected to the motor terminals PE-U-V-W. 5. When shielded motor cables are used (recommended), the cable shield must be connected to as much surface as possible on the EMC kit shielding bracket (Chapt. 2.4), but at least to the conductive assembly plate of the control cabinet. X2 - PE U V W +B -B -DC Ext. braking resistor M 3~ NOTE: When using particular wiring sleeves, the maximum cable cross section may be reduced. Screwdriver: for connecting the power module use a cross-point screwdriver (Pozidriv/Supadriv size: 1). NOTE: If synchronous machines or several motors are connected parallel to a device, the frequency inverter must be driven by a linear voltage/frequency characteristic curve P211 = 0 and P212 = 0. NOTE: The use of shielded cables is essential in order to maintain the specified noise suppression level. (see also chapt. 8.4 EMC limit value classes) NOTE: This unit can cause RFI interference. In residential areas RFI suppression may be required. (Details in Ch. 8.3/8.4) 20 Subject to technical changes BU 0500 GB

21 2 Assembly and installation Mains connection (X1 - PE, L1, L2/N, L3) Special protection is not required on the frequency inverter mains input. We recommend to use standard mains fuses (see Technical data) and a master power switch or contactor. 230 V devices from 0.25 kw to 2.2 kw may be operated either with one 230 V (L/N = L1/L2) or three 230 V (L1/L2/L3) phases. All 400 V devices and 3 kw must be supplied with three-phase mains voltage (L1/L2/L3) only. For more detailed specifications please refer to the technical data in chapt. 7. NOTE: The use of these frequency inverters on the IT network is possible after an adaptation with the jumper. For more details see chapt Cable cross-section: mm 2 solid cable mm 2 flexible cable AWG Multi-function relays (X3-1, 2, 3, 4) Parameters P434 through P443 let you set the function of these relays as desired. The maximum contact rating is 230 V AC / 24 V DC, 2 A. In the factory setting, the closed contact on terminals 3-4 (output 2, P441) indicates the frequency inverter s operational readiness. The contact is open when an error message is pending or the frequency inverter is de-energised. In the factory setting, terminals 1-2 (output 1, P434) can drive a mechanic motor brake that is thus accordingly released or applied. The appropriate delays ( secs) must be specified in parameters P107/P114 to optimise the timing.

22 NORDAC SK 500E / 520E Handbook Motor cable (X2 - U, V, W, PE) The motor cable may have a total length of 100 m in case a standard cable is used. If a shielded motor cable is used, or the cable is routed in a well earthed metallic cable duct, the maximum length of 30 m should not be exceeded. For longer cable lengths, an additional output choke (accessory) must be used. Note: Please also refer to chapter 8.4 EMC limit value classes. Note: For multiple motor use the total cable length consists of the sum of the individual cable lengths. Cable cross-section: mm 2 solid cable mm 2 flexible cable AWG Braking resistor terminal (X2 - +B, -B) Terminals +B/ -B are provided for connecting a suitable braking resistor. A shielded cable should be selected that is as short as possible. Note: Please note that the braking resistor generates a significant amount of heat. Attention! Terminals +B, -DC can be used for direct coupling of several frequency inverters. Never connect a braking resistor to -DC! Further details on direct coupling can be found in chapt Cable cross-section: mm 2 solid cable mm 2 flexible cable AWG Subject to technical changes BU 0500 GB

23 2 Assembly and installation Direct coupling (X2 - +B, -DC) Direct coupling in drive technology is feasible if several drives in a system operate as motor and generator. In this case the energy from the drive acting as the generator is fed back into the drive motor. There are advantages with regard to energy consumption and the use of braking resistors. However, the following must be considered: (1) Use a cable as short as possible between devices to be connected. (2) Make sure coupling is established only after the ready signal has been received. Otherwise there is a risk that all frequency converters are loaded via one charge circuit. (3) Make sure the coupling is separated as soon as one of the devices is no longer operable. (4) To ensure a high availability, use a (low-power) braking resistor. (5) Frequency inverters may also be operated without mains choke when coupling devices of the same power (identical type) and when identical mains impedances apply (identical cable length to the mains bar). Otherwise, implement a mains choke in each frequency inverter s power cable.

53 4 Commissioning 4 Commissioning Once the mains supply has been connected to the frequency inverter, it will be ready for use after a few moments. In this state, the application requirements can be input into the frequency inverter, i.e. parameterisation. A completely comprehensive description of all the parameters is set out in chapter 5. The connected motor should only be started using the enable signal once successful application-specific input of the parameters by qualified personnel has been achieved. ATTENTION DANGER TO LIFE! The frequency inverter is not equipped with a master power switch and is therefore always live when connected to the mains voltage. For this reason, a connected motor can also be live. 4.1 Factory settings All frequency inverters supplied by Getriebebau NORD are pre-programmed with the factory setting for standard applications with 4-pole DS standard motors (same performance and voltage). For use with motors of differing performance and power, the data from the rating plate of the motor must be input into parameters P201...P207 under the menu group >Motor Data<. NOTE: All motor data can be programmed with parameter P200. This parameter is reset to 0 = no change after this function was used! The data is automatically loaded into parameters P201 P209 once, and from here it can again be compared with the data from the motor rating plate.

55 5 Parameterisation 5 Parameterisation During operation, there are four switchable parameter sets. All parameters are visible in the delivery state but can be partially hidden with parameter P003. All parameters can be edited "online". NOTE: As there are dependencies between the parameters, it is possible for invalid internal data and operating faults to be generated. During operation, only the inactive parameters or uncritical settings should be edited. The individual parameters are combined in various parameter sets. The first digit of the parameter number indicates the Menu Group assignment. Menu group No. Main function Operating parameter display For selecting the display value physical unit. Basic parameters (P1--): Include basic frequency inverter settings, e.g. connection and disconnection modes and are sufficient for standard applications together with the motor data. Motor / characteristic curve parameters (P2--): Setting motor-specific data, important for ISD current control and characteristic curve selection by dynamic and static boost setting. Control parameters (P3--): (for SK 520E with encoder input only) Setting of the control parameters (current controller, rotation speed controller etc.) for rotation speed feedback in SK 520E. Control clams (P4--): Analogue input and output scaling, specification of digital input functions and relay outputs, as well as PID controller parameters. Extra functions (P5--): Functions dealing with e.g. the interface, pulse frequency or fault acknowledgement. Information (P7--): For display of e.g. current modes, old fault messages, device status reports or software version. Array parameter xx Some parameters in these groups can be programmed or exported in multiple levels (arrays). After parameter selection the array level must also be selected here. NOTE: Parameter P523 can be used to load the default settings for all parameters at any time. This can be helpful, for example, when commissioning an inverter, whose parameters no longer conform to the default settings. ATTENTION: All current parameter settings will be lost, if P523= 1 is set and confirmed with "ENTER". To safeguard the current settings, these can be transferred to the ControlBox or ParameterBox stores. BU 0500 GB Subject to technical changes 55

If working with an actual set point <100%, the start-up time reduces linearly according to the set point set. Under certain conditions the run-up time can be extended, e.g. FI overload, delay in desired value, curving or if the current limit is reached. P103 Braking time P s [ 2.00 ] The braking time is the time equalling the linear frequency decrease from the set maximum frequency (P105) to 0 Hz. If working with an actual set point <100%, the braking time reduces accordingly. Under certain conditions the braking time can be extended, e.g. by the selected >Switch off mode< (P108) or >Ramp rounding< (P106). BU 0500 GB Subject to technical changes 59

60 NORDAC SK 500E / 520E Handbook Parameter Setting value / description / note Device Supervisor Parameter set P104 Minimum frequency P Hz [ 0.0 ] The minimum frequency is the frequency supplied by the FI as soon as it is enabled and no additional set point is present. In combination with set points (e.g. analogue set point or fixed frequencies), these are added to the set minimum frequency. This frequency will be undershot if a. the drive accelerates from the standstill. b. the FI is locked. The frequency then reduces to the absolute minimum (P505) before it is blocked. c. the FI reverses. The change in the rotation field takes place at the absolute minimum frequency (P505). This frequency can be continuously undershot if during acceleration or braking the function "Maintain frequency" (Function Digital input = 9) was executed. P105 Maximum frequency P Hz [ 50.0 ] The frequency supplied by the FI after being enabled and once the maximum set point is present, e.g. analogue set point equivalent to P403, an appropriate fixed frequency or maximum via the ControlBox. This frequency can be exceeded by the slip compensation (P212), the "Maintain frequency" function (digital input function = 9) and the change to another parameter set with a lower maximum frequency. P106 Ramp smoothing S P % [ 0 ] This parameter enables a rounding for the run-up and brake ramps to be achieved. This is necessary for applications, where smooth, but dynamic speed changes are required. A rounding is carried out for every set point value change.

This can lead to load sags with lifting mechanism applications because the brake delays before taking the load. This application time can be taken into account with parameter P107 (Brake control). Within the adjustable application time, the frequency inverter supplies the set absolute minimum frequency (P505) and so prevents start-up against the brake and load sag when stopping. See also here the parameter >Ventilation time< P114 NOTE: For the control of electromagnetic braking (especially for lifting operations) an internal relay should be used Function 1, external brakes (P434/441). The minimum absolute frequency (P505) should never be less than 2.0Hz. NOTE: When a time > 0 is set in P107 or P114, the magnetising current (field current) strength is checked at FI power-on. Without a sufficient magnetising current present the FI remains in the magnetising state and the motor brake is not released.

62 NORDAC SK 500E / 520E Handbook Parameter Setting value / description / note Device Supervisor Parameter set P108 Switch off mode S P [ 1 ] This parameter determines the manner in which the output frequency is reduced after "Blocking" (controller enable low): 0 = Block voltage: The output signal is switched off immediately. The FI no longer supplies an output frequency. In this case, the motor is braked only by mechanical friction. Immediately switching the FI on again can lead to an error message. 1 = Ramp: The current output frequency is reduced proportionally to the remaining braking time from P103/P = Ramp with delay: As with ramp, but the brake ramp is prolonged in generator operation or the output frequency is increased with static operation. Under certain circumstances, this function can hinder overvoltage disconnection or reduce the braking resistor's power loss. NOTE: This function must not be programmed if defined deceleration is required, e.g. with lifting mechanisms. 3 = Instant DC braking: The FI immediately switches to the pre-selected direct current (P109). This DC current is supplied for the remaining proportion of the >DC brake time< (P110). Depending on the relationship of actual output frequency to max. frequency (P105) the >DC brake time< is reduced in proportion. The time taken for the motor to stop depends on the application. The time taken to stop depends on the mass inertia of the load, the friction and the DC current set (P109). With this type of braking, no energy is returned to the FI; there is substantial heat loss in the rotor. 4 = Constant brake distance: The brake ramp acts with a delay, if not moved with the maximum output frequency (P105). This leads to a similar braking distance from various current frequencies. NOTE: This function cannot be used as a positioning function. This function should not be combined with a ramp round-off (P106). 5 = Combi braking Dependent on the current DC link (UZW), a high frequency voltage is applied to the fundamental mode (linear characteristic curve only, P211 = 0 and P212 = 0). If possible, the braking time (P103) is adhered to. additional heating in the motor! 6 = Quadratic ramp: The braking ramp does not have a linear course, but is quadratically descending. 7 = Quadratic ramp with delay: Combination of functions 2 and 6 8 = Quadratic combined braking: Combination of functions 5 and 6 9 = Constant acceleration power: Only applies in field weakening range! The drive is accelerated and braked with constant electric power. The braking ramp course is dependent on the load. 10 = Distance travelled calculator: Constant distance between current frequency / speed and the set minimum output frequency (P104). 11 = Constant acceleration power with delay: Combination of functions 2 and = Constant acceleration power with delay (as 11) with additional chopper unload P109 DC brake current S P % [ 100 ] Current setting for the functions of DC current braking (P108 = 3) and combined braking (P108 = 5). The correct set value is dependent on the mechanical load and the stopping time required. A higher set value can bring large loads to a standstill more quickly.

63 5.2 Basic parameters Parameter Setting value / description / note Device Supervisor Parameter set P110 Time DC brake on S P s [ 2.00 ] The time that the motor is applied, during the direct current braking (P108= 3) function, with the current selected in the >DC brake current< parameter. Depending on the relationship of actual output frequency to max. frequency (P105) the >DC brake time< is reduced in proportion. Time starts when the enable is removed and can be cancelled with a new enable. P111 P factor torque limit S P % [ 100 ] Directly affects the behaviour of the drive at torque limit. The basic setting of 100% is sufficient for most drive tasks. If values are too high the drive tends to vibrate as it reaches the torque limit. If values are too low, the programmed torque limit can be exceeded. P112 Instantaneous current limit S P % / 401 [ 401 ] With this parameter, a limit value can be set for the torque generating current. This can prevent a mechanical overload of the drive. It cannot provide any protection against a mechanical blockade (start-up against a blockade). A safety clutch as protection cannot be dispensed with. The torque current limit can also be set over an infinite range of settings using an analogue input. The maximum desired value (comp. equivalent to 100%, P403 / P408) thus corresponds to the value set in P112. The limit value 20% of torque current can also not be under-shot by a smaller analogue desired value (P400/405 = 2) (in the servo mode with P300 = 1, not below 10%)! 401 = OFF is for the switching torque current limit off! This is also the basic setting for the frequency inverter. P113 Jog frequency S P Hz [ 0.0 ] When using the ControlBox or ParameterBox for FI control, the jog frequency is the starting value following successful enabling. As an alternative, when control is via the control terminals, the jog frequency can be activated via one of the digital inputs. The setting of the jog frequency can be done directly via this parameter or, if the FI is enabled via the keyboard, by pressing the ENTER key. In this case the current output frequency is adopted into parameter P113, and is available for a later start-up. NOTE: Specified desired values via the control terminals, e.g. jog frequency, fixed frequencies or desired analogue value are added using the correct sign. The set maximum frequency (P105) cannot be exceeded in this case, and the minimum frequency (P104) cannot be undershot. P114 Brake ventilation time S P s [ 0.00 ] Electromagnetic brakes have a physically dependent delayed reaction time during ventilation. This can lead to the motor running when the brake is still applied, which will cause the FI to trip out and display an overcurrent report. This ventilation time can be taken into account under parameter P114 (Braking control). During the adjustable ventilation time the frequency inverter supplies the set absolute minimum frequency (P505) thus preventing movement against the brake. See also here >Brake application time< P107 (setting example). NOTE: If the brake ventilation time is set to "0", then P107 is the brake ventilation and application.

P201 Nominal frequency S P Hz [ ] The nominal motor frequency determines the U/f break point, at which the FI supplies the nominal current (P204) to the output. P202 Nominal rotation speed S P rpm [ *** ] The nominal motor speed is important for correct calculation and control of the motor slippage and the speed display (P001= 1). *** The setting values are dependent upon the rated frequency inverter power or the selection in parameter P Subject to technical changes BU 0500 GB

65 5.3 Motor data/characteristic curve parameters Parameter Setting value / description / note Device Supervisor Parameter set P203 Nominal current S P A [ *** ] The nominal motor current is a significant parameter for current vector control. P204 Nominal voltage S P V [ ] The >Nominal voltage< matches the mains voltage to the motor voltage. In conjunction with the nominal frequency, this produces the current/frequency characteristic curve. P205 Nominal power P kw [ *** ] The nominal motor output is used to check the motor set via P200. P206 cos ϕ S P [ *** ] The motor cos ϕ is a significant parameter for current vector control. P207 Motor circuit S P = Star 1 = Delta [ *** ] The motor connection is decisive for stator resistance and measurement (P220) and hence for current vector control. P208 Stator resistance S P Ω [ *** ] Motor stator resistance line resistance with a DS motor. Has a direct influence on FI current control. Too high a value may lead to a possible overcurrent, too low to a low motor torque. Parameter P220 can be used for simple measurement. Parameter P208 can be used for manual adjustment or as information on the result of the automatic measurement. NOTE: The stator resistance must be measured automatically by the FI for optimum function of current vector control. P209 Idling current S P A [ *** ] This value is always calculated automatically from the motor data, if the >cosϕ< P206 and >Nominal current< P203 parameters are changed. NOTE: If the value is to be entered directly, then it must be set as the last motor data. This is the only way to guarantee that the value is not overwritten. P210 Static boost increase S P % [ 100 ] The static boost influences the current, which forms the magnetic field. This is equivalent to the idling current of the respective motor and is therefore load-independent. The idling current is calculated via the motor data. The default 100% setting is sufficient for typical applications. The setting values are dependent upon the rated frequency inverter power or the selection in parameter P200.

66 NORDAC SK 500E / 520E Handbook Parameter Setting value / description / note Device Supervisor Parameter set P211 Dynamic boost increase S P % [ 100 ] The dynamic boost influences the torque-generating current and is therefore the load-dependent parameter. The default 100% setting is also sufficient for typical applications. Too high a value may lead to an FI overcurrent. Under load therefore, the output voltage will be raised too sharply. Too low a value will lead to insufficient torque. P212 Slip compensation S P % [ 100 ] Slip compensation increases the output frequency, dependent on load, to keep the DS asynchronous motor speed approximately constant. The default 100% setting is optimal when used with DS asynchronous motors and correct motor data settings. If several motors (different load and/or power) are being driven by one FI, then the slip compensation P212 = 0% should be set. This prevents any adverse influences. This is equally valid for induction motors, that are constructed without slip. P213 ISD control boost S P % [ 100 ] This parameter influences the control dynamic of the frequency inverter's current vector control (ISD control). High settings make the controller fast, low settings slow. This parameter can be adjusted to suit the type of application, e.g. to avoid unstable operation. P214 Derivative torque S P % [ 0 ] This function enables a value for the expected torque requirement to be stored into the current controller. This function can be used in lifting applications for a better load transfer during start-up. NOTE: Motor torque is entered with a positive symbol, generator torque is identified by a negative symbol. The exact opposite applies to anticlockwise rotating field direction. P215 Lead boost S P % [ 0 ] Only with linear characteristic curves (P211 = 0% and P212 = 0%). For drives, which require a high starting torque, this parameter provides the option of switching on an additional current in the start phase. The application time is restricted and can be selected at parameter >Lead boost time< P216. All current and torque current limits (P112, P536, P537 up to 22kW ) that may have been set are disabled during the lead boost time.

In most cases, this results in a significantly improved drive behaviour because DS asynchronous motors are subject to manufacturing tolerances not documented on the rating plate.

Select a suitable motor in P200 or set parameters P201...P208 manually if the drive behaviour is unsatisfactory. 0 = No identification 1 = Identification R S : The stator resistance only (indicated in P208) is determined by repeated measurements. 2 = Motor identification: all motor parameters (P202, P203, P206, P208, P209) are determined. Procedure: a) Perform motor data identification with cold motor. Motor temperature increase is taken into account during operation. b) The maximum motor power must not be higher by more than one or lower by more than 3 power levels than the rated FI power. c) You should set the motor data as per the rating plate or P200; however, the rated frequency (P201), the rated speed (P202), the voltage (P204), the power (P205) and the Motor connection (P207) should be known at least. d) Error message E019 is generated if identification could not be successfully completed.

The higher the current control parameters are set, the more precisely the desired value of the current is maintained. Excessively high values in P312 generally lead to high-frequency vibrations at low speeds. On the other hand, excessively high values in P313 generally produce low frequency vibrations across the whole rotation speed range. If the value "Zero" is entered into P312 and P313, then the torque current control is switched off. In this case only the motor model lead is used. 68 Subject to technical changes BU 0500 GB

P318 Weak field control P SK 520E S P % [ 150 ] The weak field control reduces the desired field value when the synchronic rotation speed is exceeded. Generally, the weak field control has no function; for this reason, the weak field control need only be set, if the rotation speeds are to exceed the nominal motor rotation speeds. Excessive values for P318 / P319 will lead to control vibration. If the values are too low, the field is not weakened sufficiently during dynamic acceleration or delay times. Setting back the current control prevents it from inputting the desired current value.

At a set value of 100% the control will begin to weaken the field at approximately the synchronic speed. If values much larger than the standard values have been set at P314 and/or P317, then the weak field limit should be correspondingly reduced, so that the current control is in fact available throughout the control range.

Therefore does not lead to any rotation direction reversal. 1 = 0 10V: A set point smaller than the programmed adjustment 0% (P402) does not lead to undershooting of the programmed minimum frequency (P104). This allows a change in rotation direction with a simple voltage source and potentiometer to be carried out. e.g. internal set point with rotation direction change: P402 = 5V, P104 = 0Hz, potentiometer 0 10V rotation direction reversal at 5V when potentiometer is in the central position. When reversing (hysteresis = ± P505), the drive is at a standstill if the minimum frequency (P104) is lower than the absolute minimum frequency (P505). A brake controlled by the FI engages during the hysteresis time. The drive reverses when the minimum frequency is reached if the minimum frequency (P104) exceeds the absolute minimum frequency (P505). In the hysteresis range ± P104 the FI provides the minimum frequency (P104); a brake controlled by the FI does not engage. 2 = 0 10V monitored: If the minimum set point (P402) is undershot by 10% of the differential value from P403 and P402, the FI output switches off. Once the set point is greater than [P402 (10%*(P403-P402))], it will again deliver an output signal. E.g. set point 4-20 ma: P402: Adjustment 0% = 1V; P403: Adjustment 100% = 5V; -10% equals -0.4V; i.e. 1-5V (4-20mA) normal working range, 0.6-1V = minimum frequency set point, output switch off occurs below 0.6V (1.2mA). f / Hz P105 (fmax) P104 (fmin) OFF = 2.0V - 10% * 8.0V = 1.2V P402 = 2.0V = 8.0V P403 = 10,0V U/V 3 = - 10V 10V: An analogue set point smaller than the programmed adjustment 0% (P402) could lead to a rotation direction reversal. This allows a change in rotation direction with a simple voltage source and potentiometer to be carried out. e.g. internal set point with rotation direction change: P402 = 5V, P104 = 0Hz, potentiometer 0 10V rotation direction reversal at 5 V when potentiometer is in the central position. When reversing (hysteresis = ± P505), the drive is at a standstill if the minimum frequency (P104) is lower than the absolute minimum frequency (P505).

For rotation to the right, values between 5V and 10V are output, and for rotation to the left values between 5V and 0V. 13 = Actual rotation speed ±, is the synchronous rotation speed calculated by the FI, based on the current set point, where the null point has been shifted to 5V. For rotation to the right, values between 5V and 10V are output, and for rotation to the left values between 5V and 0V.

With On 1 the inverter reacts at a High level. This function is only possible if control of the FI is being carried out using the digital inputs. (see P509=0/1) In certain cases, the FI has to run up directly following mains switch on. P428 = 1 On can be set for this purpose. If the enable signal is permanently switched on, or provided with a cable jumper, the FI runs up immediately. P429 Fixed frequency 1 P Hz [ 0 ] Following its issue via a digital input and in enabling of the FI (right or left), the fixed frequency is used as a set point value. A negative setting value will cause a rotation and direction change (dependent upon the enable rotation direction P420 P425, P470). If several fixed frequencies are issued at the same time, the individual values are added up according to their sign. This applies also for combination with the jogger frequency (P113), with the analogue set point value (if P400 = 1) all the minimum frequency (P104). The frequency limits (P104 = f min, P105 = f max ) cannot be exceeded or undershot.

A high set value leads to less noise from the motor, but also to higher EMC radiation and a possibly reduced motor torque. NOTE: The radio interference level limit curve A 1 as per EN is adhered to when 6.0 khz is set if the wiring guidelines are complied with. Further details can be found in chapt. 8.4 EMC Limit Value Classes. NOTE: Raising the pulse frequency leads to a reduction of the output current against time (I 2 t characteristic curve). Further details can be found in chapt. 8.5 Power derating. P505 Absolute minimum frequency S P Hz [ 2.0 ] Specifies the frequency value that the FI may not undershoot. The FI switches off or goes to 0.0 Hz if the set point is lower than the absolute minimum frequency. At the absolute minimum frequency, braking control (P434 or P441) and the set point value delay (P107) are carried out. If a setting value of "Null" is selected, the brake relay does not switch during reversing. When controlling hoists, this value should be set at a minimum of 2Hz. The FI current control is operable from 2 Hz onwards, and a connected motor can supply sufficient torque. NOTE: Output frequencies < 2 Hz cause a current limitation.

At the same time this is the basic setting for this parameter. P537 Pulse switch-off S % / 201 [ 150 ] This function prevents immediate switch off of the inverter if there is an appropriate overload. The output current is limited to the set value with pulse switch-off enabled. This limitation is achieved by briefly switching off the final stage transistors; the current output frequency remains unchanged % = limit value related to the rated FI current 201 = Function is switched off NOTE: The value set here can be undershot by a smaller value in P536. The pulse switch-off can be undershot by the power derating (cf. chapt. 8.5) for low output frequencies (< 4.5 Hz) or high pulse frequencies (> 6 khz or 8 khz, P504). NOTE: When pulse switch-off is disabled (P537=201) and a high pulse frequency is selected in parameter P504, the frequency inverter will automatically reduce the pulse frequency in case of performance limits.

In case of asymmetry the FI switches off and issues error message E = Magnetization monitoring only: The magnetization current (field current) is checked upon FI power-on.

With this variant, no data is lost. They are continuously exchangeable. NOTE: If parameterisation from old frequency inverters is to be loaded into frequency inverters with new software (P707), then that ControlBox must previously have been formatted (=1) by the new frequency inverter (P550=1). Then, the data set to be copied from the old FI can be read and copied to the new one. P551 Drive profile S On / Off [ 0 = Off ] This parameter is used, depending on the option, to activate the DS401 CANopen profile or the Interbus Drivecom profile. P554 Min. chopper trigger point S % [ 65 ] With this parameter, the motor braking chopper trigger threshold can be changed. The factory setting is an optimised value for a great number of applications. This parameter value can be increased for applications where energy is intermittently fed back (crank operation) in order to minimise the power loss on the braking resistor. Increasing this setting will cause the FI to switch off faster in case of an overload. P555 Chopper power limit S % [ 100 ] With this parameter it is possible to program a manual (peak) power limit for the brake resistor. The switch-on delay (modulation level) for the braking chopper can only rise to a certain maximum specified limit. Once this value has been reached, irrespective of the level of the DClink, the FI switches the resistance to without current. The result would be an overvoltage switch-off of the FI.

This magnetisation time can be adjusted or deactivated for time-critical applications. 0 = Switched off 1 = Automatic calculation = Accordingly set time in [ms] NOTE: Settings that are too low can reduce the dynamics and start-up torque. P559 DC lag period S P s [ 0.50 ] Following a stop signal and the braking ramp, a direct current is briefly applied to the motor to fully bring the drive to a stop. The current application time can be set via this parameter, dependent on the mass inertia.

124 NORDAC SK 500E / 520E Handbook 8.3 Electromagnetic compatibility (EMC) All electrical equipment that have an intrinsic, independent function and are placed on the market as individual units for users must comply from January 1996 with the EEC directive EEC/89/336. There are three different ways for manufacturers to display compliance with this directive: 1. EC declaration of conformity This is a declaration from the manufacturer stating that the requirements in the applicable European standards for the electrical environment of the equipment have been met. Only those standards which are published in the Official Journal of the European Community can be cited in the manufacturer declaration. 2. Technical documentation Technical documentation can be produced which describes the EMC characteristics of the device. This documentation must be authorised by one of the Responsible bodies named by the responsible European government. This makes it possible to use standards that are still being prepared. 3. EC type test certificate This method only applies to radio transmitter equipment. SK 500E / 520E frequency inverters, therefore, have a single function, if they are linked to other equipment (e.g. a motor). The base units cannot therefore carry the CE mark that would confirm compliance with the EMC directive. Precise details are therefore given below about the EMC behaviour of this product, based on the proviso that it is installed according to the guidelines and instructions described in this documentation. Class A, group 2: General, for industrial environments Complies with the EMC standard for power drives EN , for use in secondary environments (industrial) and when not generally available. Class A, group 1: Interference suppressed, for industrial environments In this operating class, the manufacturer can certify that his equipment meets the requirements of the EMC directive for industrial environments with respect to their EMC behaviour in power drives. The limit values correspond to the basic standards EN and EN for interference resistance and interference emission in industrial environments. Class B, group 1: Interference suppressed for domestic, commercial and light industry environments In this operating class, the manufacturer can certify that his equipment meets the requirements of the EMC directive for domestic, commercial and light industry environments with respect to their EMC behaviour in power drives. The limit values correspond to the basic standards EN and EN for interference resistance and interference emission. NOTE The NORDAC SK 500E / 520E frequency inverters are designed solely for commercial applications. They do not therefore meet the requirements of the standard EN for radiation of harmonics. This unit can cause RFI interference. In residential areas RFI suppression may be required. (Details in chapt. 8.3/8.4) 8.4 EMC limit value classes Please ensure, that these limit value classes are only reached if the standard pulse frequency (6 khz) is being used, and the length of the shielded motor cable does not exceed the limits. In addition, it is essential to use wiring suitable for EMC. (Switch box / Cable clamping) The motor cable shielding is to be applied on both sides (inverter shield angle and the metal motor terminal box). 124 Subject to technical changes BU 0500 GB

126 NORDAC SK 500E / 520E Handbook 8.5 Reduced output power The SK 500E / 520E frequency inverter series has been designed for specific overload situations. Example: a 1.5-fold over-current is possible for 60 secs. A 2-fold over-current is possible for ca. 3.5 secs. The overload resistance is reduced in the following cases: o Output frequencies < 2 Hz and direct voltages (stationary needle) o Pulse frequencies exceeding the rated pulse frequency (P504) o Raised mains voltages > 400V o High temperature of the heat sink The following characteristic curves allow the respective power reduction to be read Reduced output current due to pulse frequency This illustration shows the allowed current for 230V and 400V devices caused by the pulse frequency. For 400V devices the reduction starts with a pulse frequency of 6kHz. For 230V devices with a pulse frequency of 8kHz. These curves reflect the power loss in the frequency inverter s final stage. The current must be lowered with increasing pulse frequency in order to keep the power loss near to constant.

127 8 Additional information Reduced over current due to time The possible overload resistance depends on the overload duration. The following tables list some appropriate values. Once such a limit value was reached the frequency inverter must have sufficient time to regenerate at a low load. The limit values given in the table are reduced if the device is operated in the overload area at brief intervals. 230 V devices: Reduced overload resistance (ca.) due to pulse frequency (P504) and time Pulse frequency [khz] Time [s] > % 150% 170% 180% 180% 200% % 140% 155% 165% 165% 180% 12 96% 130% 145% 155% 155% 160% 14 90% 120% 135% 145% 145% 150% 16 82% 110% 125% 135% 135% 140% 400 V devices: Reduced overload resistance (ca.) due to pulse frequency (P504) and time Pulse frequency [khz] Time [s] > % 150% 170% 180% 180% 200% 8 100% 135% 150% 160% 160% 165% 10 90% 120% 135% 145% 145% 150% 12 78% 105% 120% 125% 125% 130% 14 67% 92% 104% 110% 110% 115% 16 57% 77% 87% 92% 92% 100% BU 0500 GB Subject to technical changes 127

128 NORDAC SK 500E / 520E Handbook Reduced over current due to output frequency A monitoring circuit determining the IGBTs (integrated gate bipolar transistor) temperature caused by the high current is provided in order to protect the final stage in case of low output frequencies. A pulse cut-out (P537) with variable limit is assumed in order to prevent currents above the limit indicated in the diagram. For this reason, currents exceeding the rated current by factor 1.1 cannot be assumed at standstill and 6 khz pulse frequency. I / I N impermissible range x ( f) In_60sec ( f) In_1sec ( f) f Output frequency [Hz] Please refer to the following tables for the upper pulse cut-out limit values resulting from various pulse frequencies. Depending on the pulse frequency, the value ( ) you can set in parameter P537 is always limited to the value given in the tables. Values below this limit can be set as desired. 230 V devices: Reduced overload resistance (ca.) due to pulse frequency (P504) and output frequency Pulse frequency [khz] Output frequency [Hz] % 170% 150% 140% 130% 120% 110% % 153% 135% 126% 117% 108% 100% % 136% 120% 112% 104% 96% 95% % 127% 112% 105% 97% 90% 90% % 119% 105% 98% 91% 84% 85% 400 V devices: Reduced overload resistance (ca.) due to pulse frequency (P504) and output frequency Pulse frequency [khz] Output frequency [Hz] % 170% 150% 140% 130% 120% 110% 8 165% 140% 123% 115% 107% 99% 90% % 127% 112% 105% 97% 90% 82% % 110% 97% 91% 84% 78% 71% % 97% 86% 80% 74% 69% 63% % 85% 75% 70% 65% 60% 55% 128 Subject to technical changes BU 0500 GB

129 8 Additional information Reduced output current due to mains voltage The thermal device configuration is based on the rated currents. Consequently, it is not possible to draw higher currents to keep the output power constant in case of lower mains voltages. In case of mains voltages above 400 V the permissible permanent output currents are reduced inversely proportional in order to compensate for the increased switching losses. I / I N k Unetz ( Unetz) Unetz 480 Mains voltage [V] Reduced output current due to heat sink temperature The output current reduction also considers the heat sink temperature in order to allow for a higher load, in particular with higher clock pulses and low heat sink temperatures. The reduction is correspondingly increased with high heat sink temperatures. Ambient temperature and device ventilation conditions can thus be optimised. 8.6 FI circuit breaker operation The frequency inverters are designed for operation on a 30 ma AC/DC sensitive FI circuit breaker. The leakage currents towards PE must be reduced if several frequency inverters are operated on one FI circuit breaker.
