3 ATTENZIONE! All the installation, maintenance and disinstallation operations described in this manual must be carried out strictly respecting the current "work safety" laws: in fact, the indications given here are of a general nature, and cannot take into account the specific features of every possible installation. It is therefore essential to fully observe the relevant safety regulations for the specific context. IF THERE IS ANY INCONGRUITY BETWEEN THE POSSIBILITY TO CARRY OUT AN OPERATION DESCRIBED IN THIS MANUAL AND THE WORK SAFETY REGULATIONS (ESTABLISHED BY THE LAW OR BY THE PERSON IN CHARGE OF THE PLACE WHERE THE OPERATIONS ARE CARRIED OUT), RESPECT OF THE SAFETY REGULATIONS MUST ALWAYS TAKE PRIORITY. This manual applies to the following products: Inverter module "NERIDRIVE Small" based on power modules Infineon "CIPOS" (Version Hardware, Firmware 5.00 and following) Programming keyboard "ALS-01", "ALS-10R" (Firmware 5.00 and following)

4 1.1 - SAFETY WARNING: 1 - INTRODUCTION THE FOLLOWING DANGER SYMBOLS (USED IN THIS MANUAL) INDICATE INFORMATION THAT MUST BE READ WITH PARTICULAR ATTENTION TO ENSURE PEOPLE'S SAFETY. Indicates information about the presence of a dangerous voltage level that could cause serious injury or death Indicates warnings about general hazards, or information that is particularly important for good inverter operation Highlights a part that must be read in order to make it easier to use the information given in this manual DESCRIPTION OF THE PRODUCT: The NERIDRIVE Small inverter is designed to allow a speed variation in asynchronous three-phase motors of any polarity, with 230/400 V windings that can work at a frequency of 50 or 60Hz. The NERIDRIVE Small inverter is designed, built and sold as a component to be incorporated in asynchronous three-phase motors. Its framework is of standard dimensions, in the standardised IEC sizes 56, 63, 71, 80, 90, 100 and 112, according to the instructions given in this manual. The inverter must be assembled on the motor by NERI MOTORI. The "motor + inverter" system obtained once the inverter has been correctly electro-mechanically assembled on the motor is defined in this manual with the term "inverter motor". The mechanical and electrical installation of the inverter motor, and its initial start-up, must be carried out by professional assemblers and installers who have the general technical knowledge to install the product correctly. This documentation is a specific guide for: assemblers or manufacturers performing the mechanical assembly of the inverter unit on the motor and making the electrical connection between the two components; assemblers or installers performing the electrical installation of the inverter motor in a system, or incorporating it in equipment or systems; installers or technicians performing the initial start-up and calibration of the inverter motor once it has already been installed in the system. This manual is made available to the assembler so he can fulfil (with regards the installation of the inverter only) the protection requisites envisaged by Directive 89/336/EEC in relation to ELECTROMAGNETIC COMPATIBILITY and produce an installation compliant with the EN regulations. In any case however, the manufacturer of the equipment, system or installation is responsible for the overall electromagnetic compatibility result with reference to the Standardised Regulations applicable to his product, so he has the faculty not to respect (fully or partially) the contents of this manual and to adopt alternative protection solutions instead. The information given here is only valid for NERIDRIVE Small inverters with a three-phase voltage supply, and (unless otherwise indicated) for the sizes available on the market. pag. 4 NERIDRIVE Small (Rev07)

5 1.3 - GENERAL CHARACTERISTICS: Power supply: from the mains, single phase 230 V / 50 Hz (on request from 110 V / 50 Hz with power derating). Operating limits: from 155 V (*) to 264 V - frequency from 42 Hz to 60 Hz Output: three-phase for asynchronous motors with windings up 230 V (on request from 110 V / 50 Hz with power derating) Output frequency: from 0 to 200 Hz. The minimum operating frequency at which the motor reaches the nominal torque depends on the motor characteristics. Type of operation: V/F SVM ( Space Vector Modulation ) Type of adjustment: PWM (Pulse Width Modulation) with maximum frequency 15 khz. Ambient temperature: from 0 C to 40 C while operating (without deratings); from -25 C to 75 C with no voltage (limit: 90 C for max. 24h) Relative ambient humidity: not significant if correctly assembled on the motor. Protection degree: Standard IP54, on request up to IP65, in accordance with IEC 34.1 Ambient altitude: max. 1000m above sea level Deratings: -3% for every C beyond 40 and up to 60 C; -5% for every extra 1000m a.s.l. beyond 1000m (*) = the lower limit voltage ensures that the electronics will not turn off in the event of low supply voltage, however, under conditions of power supply voltage reduced the motoinverter provides a torque less than nominal, then the output power at the nominal speed can be smaller than the motor plate data. In case of high mechanical load and low supply voltage can occur the intervention of overcurrent protection.

6 1.5 - AVAILABLE RESOURCES: The inverters of the NERIDRIVE Small series, "cipos" version are equipped with the following I/O command and interface resource: 4 inputs with extra-low safety voltage, with programmable functions (type of command contact: potential-free, with 1 common terminal) 1 signalling outputs with programmable functions (output contact: N.O., maximum controllable voltage 110 V AC/DC - 4 A resistive) 1 analogue input for proportional speed reference 0-10 V (with input impedance 1 kohm) 1 serial port RS485 for programming and interface in Modbus/RTU protocol (with a speed of 9600/19200 bits) PRODUCT IDENTIFICATION AND LABELLING: Each NERIDRIVE Small is identified by a label showing the following data: Voltage, frequency and rated current on the inverter input side Serial Number and rated power NERIDRIVE type Markings according to European Directives and any approvals Note that the maximum supplied power (intended as the maximum nominal power) may not coincide with the actual power of the inverter motor unit, which is always determined by the power of the combined motor. Thanks to its advanced algorithm for power adjustment and operating parameter measurement, the inverter module is able to automatically adapt to the motor power. The right current value for the / - 400/230 V motors, is the 230 V related current. Inside the box (on the electronic tab), some plate data - such as the serial number and nominal supplied motor power - are given on other labels too, as indicated in paragraph pag. 6 NERIDRIVE Small (Rev07)

8 2 - ASSEMBLING OF THE MOTOINVERTER MECHANICAL INSTALLATION OF THE INVERTER ON THE MOTOR. If you have purchased an inverter motor that is already assembled, or you only need to carry out the electrical installation, you don't need to read this paragraph. ATTENTION: before starting the assembly, make sure the motor plate data are compatible with the specific characteristics of the inverter used (shown on the label of the inverter itself and on paragraph 1.6 of this manual). If you have any doubts, contact our Technical Service. List of the accessories supplied with the inverter module to be assembled on your motor: 3 wires (length 17 cm, section 1.5 mm 2 ) terminated with 4 mm eyes and a 6.3 mm female faston with faston-cover. This assembly phase involves the mechanical coupling of the inverter motor base box with the motor terminal block cover base, and also the preparation of the connection cables between the motor terminals and the inverter tab. Check that the terminal block cover base on your motor (where the terminal cover is usually fitted) has dimensions and threaded bore centre distances suitable for coupling with the flange on the base of the inverter (see chapter 6). Connect the motor terminals so the motor adapts to the 230 V supply voltage (delta connection on 230/400 V motors) for inverter motors suitable for a 230 V single-phase supply. Connect the eye terminals of the wires (supplied) to the motor terminals, then tighten the bolts with a suitable tightening torque. Respect the appropriate safety distances between the parts which are live during operation and the framework (or other neutral parts) of the motor. Position four M4 screws on the motor terminal cover. Choose the right screw length considering the thickness of the inverter box and the gasket (approx. 4 6 mm) Position the base of the inverter box on the motor, threading the three wires (previously connected to the motor terminals) through the central slots on the gasket. Tighten the four screws that fix the inverter base to the motor terminal block base, making sure the gasket is correctly pressed all along the point of contact between the inverter and the motor. Make the electrical connection of the inverter tab as described in the next paragraph ELECTRIC CONNECTION BETWEEN THE INVERTER AND THE MOTOR If you have purchased an inverter motor that is already assembled, or you only need to carry out the electrical installation, you don't need to read this paragraph. This assembly phase involves the electrical connection between the motor and the inverter tab. The base of the inverter module box is already coupled with the motor framework, and the eyeterminated wires (motor side) and 6.3 mm female faston (inverter side) are already connected to the motor terminals, as described in the previous paragraph. Connect the female fastons from the motor windings to the connection terminals on the inverter tab (refer to paragraph 3.2.1, reference no.3). If several inverter motors are assembled in series, it's a good idea to always respect the same phase sequence so that the motor rotation directions (defined in this manual as "FWD" and "REV") are coherent throughout your entire production. ATTENTION: if separate ventilation with a supply of 24V DC or 220/380V AC is envisaged for the motor, please contact our technical office for the details of the electrical connection. pag. 8 NERIDRIVE Small (Rev07)

9 3 - ELECTRIC INSTALLATION IN THE SYSTEM It's essential to read this chapter before carrying out the electrical installation of the new inverter motor or the spare part, or the reinstallation following system maintenance. The inverter motor must be installed in the system by electric installers, manufacturers or professionals with the technical and professional skills and knowledge laid down in the current legal regulations. The installation operation must not be carried out by private individuals or end users. Apart from the intervention (using suitable tools - a screwdriver with a 3 mm blade) on the connection terminals, carried out while the inverter is de-energised, no other operation is required or allowed on any part of the inverter motor. In particular, the separation of the electronic tab from the upper radiator is not permitted, and any tampering, modification, replacement or removal of any electronic component on the inverter motor is forbidden. At the end of the wiring operations (described in this chapter 3) and before energising, it is essential to close the inverter cover to guarantee the electrical safety of the installation POSSIBLE OPERATING MODES Motor rotation speed The motor speed can be set and modified (within the limits established by the parameters) in the following ways: With a proportional reference: from a potentiometer; from an energised analogue signal (0 10 V); from a current loop signal (0 20 ma or 4 20 ma). Via digital selection: in potentiometer motor mode, with two digital inputs - "increase" / "decrease"; in potentiometer motor mode from the local panel "P2"; in "multi-speed" mode, with up to 4 frequencies stored in the inverter parameters and selected thanks to the combination of two digital inputs; using the RS485 with Modbus/RTU protocol; from the ALS-01 terminal Start and stop commands These can be enabled via the digital inputs on the tab, with the following functions: 1 permanent "start" contact (closed = "start") and 1 permanent "reverse direction" contact (closed = "reverse"); 1 impulsive "forward movement/stop" contact (an impulse to the idle motor starts it, while an impulse to the moving motor stops it), 1 impulsive "backward movement/stop" contact (an impulse to the idle motor starts it, while an impulse to the moving motor stops it); permanent forward movement (FWD) and backward movement (REV) contacts. Of course, the start/stop commands can also be given via the RS485 with Modbus/RTU protocol, and via the ALS-01 terminal. NERIDRIVE Small (Rev07) pag. 9

The external section of the cable must be circular and its diameter must be suitable for the cable gland, as indicated in paragraph 1.4 (to guarantee the correct grip of the cable gland). No shielding is needed for the supply cable. A correct earth connection, on the other hand, is fundamental for purposes of electrical safety and EMC protection. For this reason, the PE terminal must be connected to the protection wire located in the control panel. The inverter is equipped with a spring terminal board (1) of high quality that ensures the maximum mechanical connection and good electrical continuity. The recommended section for the power supply wires is 1.5 mm 2 and do not need crimped pins. Press perpendicular to the surface of the circuit board on the appropriate orange terminals with a screwdriver having a mm blade and insert the stripped wire for about 5 mm until you meet resistance, then release the terminal and check, with a slight pull on the wire, the connection sealing. The type of the fuse (2) protection is 5x20 mm / 250 V - T10 A (0.75 kw). pag. 10 NERIDRIVE Small (Rev07)

12 Connection of digital inputs 1 4 in the "basic" operating modes The motoinverter can be controlled by programming the input functions via parameter S011 (see paragraph 4.3). Refer also to paragraph 4.4 for other operating modes and for a detailed description of the basic ones indicated below. Command type: Connection on connector 8 Note: the commands must be maintained Start + Reversal of the rotation direction n.c. n.c. Start Reversal S011 = 4 (ref. paragraph 4.3) Attention: if P001=4, inputs 8.3 e 8.4 assume a particular function (see paragraph 4.4) Forward movement + Backward movement Start/Stop (with self-hold of the START command) n.c. n.c. FWD REV jog STOP REV movement START Note: the commands must be maintained With the motor idle, the activation of one of the inputs starts up the motor in the corresponding movement direction. S011 = 3 (ref. paragraph 4.3) To reverse the movement direction, the REV contact (8.1) must be maintained. The STOP contact (8.3) is normally closed. An impulse on START (8.2) will start up the motor. The opening of the STOP command will stop the motor. The activation of "jog movement" (8.4 - the contact must be maintained) causes the motor to stop (if it was moving). When the motor is idle, the START contact becomes impulsive (the motor starts up when START is pressed and stops when START is released). S011 = 12 (ref. paragraph 4.3) Potentiometer motor (backward movement, forward movement, increase speed, decrease speed) REV FWD +SP -SP Multispeed 1 Start/Stop, Fwd/Rev and 4 random speeds (self-powered inputs) bit 2 1 bit 2 0 START REV Note: the commands for forward and backward movement must be maintained. Keeping IN2 (8.2) closed, the speed increases. Keeping IN1 (8.1) closed, the speed decreases. At switch-on (or start), the motor will assume the last speed set. S011 = 8 (ref. paragraph 4.3) Note: the commands for forward and backward movement must be maintained. For the combination of inputs IN3 (8.3) and IN4 (8.4), see the description of the "F" parameter group on paragraph 4.3 S011 = 5 (ref. paragraph 4.3) Multispeed 2 two forward speeds + two backward speeds Multispeed 3 4 integrable frequencies matched with the inputs F4 F3 F2 F1 BACKWARD FORWARD V4 V3 V2 V1 Note: the commands for forward and backward movement must be maintained. For the programming of the speeds (F1...F4), see the description of the "F" parameter group. S011 = 10 (ref. paragraph 4.3) Each input is matched with a frequency, programmed in the "F" parameters. The simultaneous activation of several inputs allows you to obtain a motor speed determined by the sum of the matched frequencies.

Use a 2-pole, braided, shielded-conductor cable compliant with Standard IEEE RS485. Do not interrupt the electrical continuity of the shield. Reduce the unshielded cable parts as far as possible. Connect the shield to an effective earth point from the "MASTER" side only. Make a multi-point network by linking together all the RA terminals and then all the RB terminals, respecting the typical layout (avoid backbones as the starting point for Slave connections, and avoid star connections). TYPICAL MASTER OUTPUT LAYOUT (line polarisation): Check the Master is able to polarise the line with an output layout compatible (as far as possible) with the one shown here. If you have any doubts, don't hesitate to contact our Technical Service for further information. If the Master doesn't have an output circuit that can polarise the line, transmission via the serial line can still work but performance levels may be reduced.

15 3.3 EMC PROTECTION The inverter is equipped as standard with a passive filtering stage, which means its installation complies with Standards EN50081 (Class A, industrial environment). The emission characteristics are available upon request once the combination of the inverter unit with the customer's motor has been defined. If the installation needs to respect the limits envisaged for Class B (Standard EN50081), the filtering stage closure jumper must be assembled on the PE (reference no. 19, par of this manual). This jumper IS NOT USUALLY ASSEMBLED on NERIDRIVE Small inverters. If it is assembled, the runaway current may cause the system's 30 ma differential protection devices to be triggered, especially if those devices also cover other electric loads with similar filtering characteristics. In this case, the people in charge of electrical maintenance and safety in the place where the inverter motor is installed must identify and adopt the most suitable protection measures. ATTENTION: in any case, the presence of the EMC filter on the inverter tab may, at the moment of energisation, trigger the differential protection devices if they aren't correctly sized. You are advised to use residual current circuit breakers suitable for the supply of loads with EMC filters. The installer can contact our Technical Service if any further information is required. Under no circumstances must you remove the earth wire connected to the PE terminal of the inverter tab in order to handle any differential protection device intervention problems; this would make the installation non-compliant from an electrical safety and EMC protection viewpoint DISINSTALLATION AND OPERATIONS WITH CASING OPEN ATTENTION - RISK OF ELECTRIC SHOCK: do not carry out any type of direct operation on the internal parts of the inverter motor, or open its cover, if it is powered. If you are in any doubt, disconnect the supply voltage to the inverter motor (using the specific instruments on the control panel) then wait at least 60 seconds before opening the cover. When the inverter has been disconnected from the power supply, you can open the upper cover of the inverter by loosening the four screws. Any necessary maintenance or disinstallation work can then be carried out. All installation, maintenance and disinstallation operations must be carried out strictly respecting the current "work safety" laws: in fact, the indications given here are of a general nature, and cannot take into account the specific features of every possible installation. It is therefore essential to fully observe the relevant safety regulations for the specific context. If there is any incongruity between the possibility to carry out an operation described in this manual and the work safety regulations (established by the law or by the person in charge of the place where the operations are carried out), respect of the safety regulations must always take priority. 4 - INITIAL START-UP, PROGRAMMING AND CALIBRATION FIRST ENERGISATION AND QUICK START-UP. NERIDRIVE Small (Rev07) pag. 15

16 Energisation is only permitted once the inverter cover has been replaced and the four fixing screws have been tightened. Pay special attention to the correct positioning of the gasket between the cover and the base of the box before tightening the screws. The initial start-up operations must only be carried out by personnel who have been suitably trained, or who possess the skills and/or professional qualifications needed to work on live systems and moving mechanical parts. The instructions given in this paragraph lead to the rotation of the motor shaft. It is therefore essential to make sure the inverter motor has already been mechanically fixed to a solid anchor point (if not connected to the mechanical transmission) or can turn without damaging the transmission parts or creating hazards for people/ animals (if already connected to the mechanical transmission). After making at least the power connection (as explained in paragraph 3.2.2) and powering the inverter motor, follow the instructions below to start up the inverter motor from the ALS-01 terminal (only for "/S" and "/F" models with an RS485 connector). Ref. Operation Visualisation on the display Connect the terminal to the 4-pole connector of 1 the inverter motor, as explained above.

17 4.2 - DESCRIPTION OF THE ALS-1 PROGRAMMING TERMINAL The programming terminal must be connected to the inverter via the right-hand 4-pole female connector on the back of the inverter box. The terminal can be connected and removed even while the inverter is powered. To connect the terminal: Loosen the remove the connector protection cap; Insert the mobile connector of the terminal (making sure the phase tooth inside the connector is aligned); Tighten the mobile connector. As soon as it is connected, the terminal shows the software revision code for 2 seconds then goes to the "D" visualisation mode set via the parameters (see the description of parameter S010 in the next paragraph). If the parameter S011 is already set at a value of "7", the keyboard can command the inverter motor; this means you can start up the motor and adjust its speed as explained in the next point. Functions of the keys: 1) Inverter motor command mode: FWD/STOP: in terminal/modbus control mode (S011 =7) this allows you to start the motor in forward movement if it's idle, or stop it if it's moving. REV/STOP: in terminal/modbus control mode (s011 =7) this allows you to start the motor in backward movement if it's idle, or stop it if it's moving. : increases the speed : reduces the speed 2) Parameter selection mode: M: changes the group of the parameters ( S P F A O D S ecc ) : moves on to the next parameter : moves back to the last parameter E: enters the visualised parameter 3) Altering the visualised parameter: : increases the value : reduces the value E: memorises the value M: quits the parameter NERIDRIVE Small (Rev07) pag. 17

18 Connecting the programming terminal ALS-01 by ALS-01 adapter: To program the parameters using the programming terminal ALS-01 if you do not have the motoinverter version "/ S" or "/ F" is essential to use the ALS-b-adapter. It can be ordered separately from motoinverter and terminal. Follow all the requirement for electrical safety related to the personnel performing the operations of commissioning, programming and maintenance as shown in this manual, it is essential to properly connect the adapter to the inverter in order to prevent damage to the equipment. Refer to the following figure: pag. 18 NERIDRIVE Small (Rev07)

BUS VOLTAGE V Default value Unit of measure S006 NOMINAL SPEED - - Rpm S007 REDUCTION RATIO from -10 to S008 NUMBER OF MOTOR POLES S009 SWITCHOVER FREQUENCY 7, khz S010 "D" MENU PARAMETER VISUALISED AT SWITCH-ON from 1 to S011 SPEED REFERENCE CONFIGURATION from 1 to S001 - MAXIMUM FREQUENCY - This is the frequency reached with the speed reference at maximum (10 V in the case of a voltage reference, 20 ma in the case of a current reference - see par for the settings). All the models have a factory setting of 50 Hz. There is no limit to the increase of this value (up to 200 Hz), so it is necessary to pay attention when evaluating the maximum speed that the drive and mechanics connected to the motor can actually tolerate (on a 2-pole 200 Hz motor, they correspond to over rpm). S002 - MINIMUM FREQUENCY - This is the frequency reached with the speed reference at 0 V. It has a factory setting of 3 Hz, but this value can be reduced. There is no limit to the increase of this value, until a value of 0.1 Hz is reached at less than the maximum frequency set in S001. With the reference at 0 V, the motor can be stopped regardless of the value set for this parameter, by setting parameter P006 at "1". S003 - ACCELERATION RAMP - This is the time taken to accelerate from 0 to 50 Hz. The total motor acceleration time will depend on the speed jump made (e.g. if the set maximum frequency is 100 Hz, a value of "5" in this parameter will produce an acceleration time of 10 seconds in the phase from 0 to 100 Hz). Attention: excessively short ramps can cause the protection device to intervene due to overcurrent in acceleration and overvoltage in deceleration. Below 1.00 s, it varies in steps of 0.05 s. The maximum settable value is 30 s. S004 - DECELERATION RAMP - This is the time taken to decelerate from 50 to 0 Hz. The same principle applies as for acceleration. S005 - D.C. BUS VOLTAGE - This parameter should usually be kept at the factory setting, although it can be modified for particular applications. S006 - NOMINAL MOTOR SPEED - This parameter cannot be modified. It depends on the value set in S008. S007 - REDUCTION RATIO - Used to set the mechanical ratio between the motor shaft and the load. Starting from parameter S006, it allows you to visualize the power drive output speed in parameter D002. A value of 1 is neutral (no ratio between the motor and the output); values from -10 to -1 are multiplication ratios; values from 2 to 9999 are reduction ratios. A value of 0 is permitted, but has no meaning. S008 - NUMBER OF MOTOR POLES - This parameter is used to set the number of poles, which must - of NERIDRIVE Small (Rev07) pag. 19

20 course - be that of the motor combined with the inverter in order to obtain correct speed visualizations (in the "D" group parameters). S009 - SWITCHOVER FREQUENCY - This is the switchover frequency of the IGBTs. High values allows the inverter motor to operate without audible frequencies being generated. The inverter motor can be enabled (parameter P009) to autonomously reduce the switchover frequency up to 7.5 khz during operation in the event of a prolonged overload. S010 - "D" MENU PARAMETERS VISUALISED AT SWITCH-ON - At switch-on, the programming terminal goes directly to the visualisation indicated in this parameter. Refer to the list of "D" parameters for the possible visualisations. S011 - SPEED REFERENCE CONFIGURATION - Selects the main speed reference.

22 operating mode in which the speed reference is the one set in parameter S011, and the START/REVERSE commands are the ones selected in this parameter. P004 - ROTATION DIRECTION AT SWITCH-ON - Used to reverse the motor rotation direction (the same result is obtained - not altering the programming - by inverting the two motor phases). P005 - MOVEMENT SAFETY - This operating mode can be obtained with all the reference configurations set via parameter S011. It's a particularly important mode in all applications where any possible voltage failure (e.g. a blackout) and the subsequent power supply reset could present a risk for people or objects when the mechanical parts of the system/machine resume their movement. If parameter P005 has a value of 1, when the power supply is restored the START command (which may have remained enabled) returns to "disabled" status and is then enabled again so that the motor can resume its rotation. If parameter P005 has a value of 0 (the default value), when the power supply is restored the motor (which was moving when the voltage failure occurred) automatically begins rotating again. This operating mode is usually required for various types of application (cooling pumps, ventilation systems, etc.). It's very important to note that this mode is handy for ensuring a high level of safety, but it has no redundancy control and is not available in inverter motors with "inherent safety" components. Setting parameter P005 on "restart not permitted" does not therefore mean the inverter motor installer can ignore the need to adopt the most suitable solutions (outside the inverter motor) for ensuring user safety, as indicated in the "Machinery Directive" and the standardised regulations applicable for this product. P006 - FREQUENCY AT ZERO REFERENCE - This parameter indicates whether the motor must move at the minimum frequency (set in parameter S002) or remain idle when the analogue speed reference is zero. P007 - BRAKE AT ZERO FREQUENCY - Indicates whether the motor shaft must be free or in torque below the minimum frequency (set in parameter S002). At zero speed, the torque value is about 1/5 of the nominal torque. Pay great attention when using the operating mode with the motor in torque when the shaft is idle, as the motor may overheat; for this reason, you are strongly advised not to use it if there isn't at least an auxiliary servo ventilation device on the motor. P008 - POTENTIOMETER MOTOR RESET - In modes where a potentiometer motor is envisaged (S011= 6 or 8), this allows you to memorise the last speed set or to restart from the minimum speed at the first start-up after every new energisation of the inverter motor. Attention: the motor speed changes straight away, but is memorised by the inverter roughly every 5 seconds, so a de-energisation immediately after a speed change may not allow a restart at the last speed set. P010 - P011 - PROTECTION cos - INTEGRATION TIME - During operation, the inverter measures the motor power factor (which, when it rises above certain limits, indicates that the motor is overheating). The value set in P010 determines the threshold, while the value of P011 represents the integration time (in seconds) for the average of 5 values. When the average value exceeds the threshold value, the "PF" protection is triggered. P012 - MINIMUM INVERTER FREQUENCY - This parameter establishes the minimum frequency at which the inverter begins to generate a voltage; the "MINIMUM FREQUENCY" value set in parameter S002 determines the minimum speed to which the motor can be taken from the speed reference, but if this value is also set at 10 Hz for example, the supply to the motor at "START" will be generated starting from the "minimum inverter frequency". P013 - P014 - NUMBER OF RESTART ATTEMPTS IN THE EVENT OF AN ERROR - TIME BETWEEN ONE RESTART ATTEMPT AND THE NEXT - Allows the inverter to attempt an automatic restart in the event of an error (due to the triggering of an internal protection device). You can establish the number of pag. 22 NERIDRIVE Small (Rev07)

23 attempts, and the standby time between one attempt and the next. This function should be used with due caution, but it's very handy - for example - if the system is not monitored or for controlling hydraulic pumps or ventilation systems where manual protection device reset may not be easy or prompt enough for continuous system operation. If parameter P013 is set at "0" (factory setting), the automatic restart function is disabled. If the error is due to reversible malfunctioning (e.g. overtemperature), only a de-energisation or a new start signal can restart the motor. When programming the automatic reset function, bear in mind system usage safety and adopt all the necessary measures (outside the inverter) for preventing an automatic motor restart if there could be any hazardous situation for maintenance workers. P018 - ALARM MEMORY RESET - The inverter is equipped with a function for memorising the number and type of alarms that occur (only the last 5). These alarms can be visualised in parameters D100 - D105 (see paragraph 5.2). Using the ALS-01 (or ALS-10R) keyboard to set a value of 1 for parameter P018 and then pressing ENTER, the alarm memory is reset. P019 - CURRENT LIMIT - In this parameter you can set the current threshold beyond which the inverter goes into protection mode due to motor overload. By calibrating this parameter at a reasonable motor overload current, you can obtain excellent performance on surge, movement direction reversal, and resistant torque peaks, with the best possible motor protection level. The correct combination of this protection with the protection relating to motor power factor control (parameters P010 and P011) ensures the perfect control of every type of motor overload (both instantaneous and prolonged). The threshold to be set will depend on the motor overload percentage considered reasonable - this can range from the nominal rating of the motor itself (no overload allowed) to the value of the maximum current that can be supplied by the inverter. You are advised to take due care when setting this parameter, as an excessively high value could stall the inverter motor in the event of prolonged mechanical overload on the motor axis. Stalling is a condition whereby the motor shaft is blocked but the inverter continues to power the motor and the electric windings absorb a current which, although excessive for the motor, is not detected as anomalous by the inverter as it is lower than the value set in P019. The criterion for setting this parameter correctly is to read the motor rated current (in motors with 230/400 V windings, two current values are indicated for the star and triangle connections; the one for the 400 V connection is always the lower of the two) and not to exceed 120% (multiplying the IRating value of the rated current by 1.2 to obtain the value to be set in P019). If possible, check the maximum mechanical load conditions envisaged and permitted on the motor during normal operation, and check the protection device is not triggered. If error OL appears (see paragraph 5.2 of this manual), gradually increase the set value and repeat the test up to 150% (1.5 x IRating ). In particular conditions, the value set in P019 may also be equal to double the rated motor current, without reducing the protection and reliability of the inverter motor. If the protection device is triggered during operating tests even at 150% of the rated current however, it's necessary to make a detailed examination of the sizing of the inverter motor in the application. In this case, please contact our Technical Service. If the inverter module is combined with motors smaller than the nominal size, the original factory setting of parameter P019 should be recalibrated. The following table provides a guideline for recalibration in the case of a 230 V single-phase power supply and an inverter combined with 230/400 V motors with a triangle connection.

In applications where there is a not negligible pumping effect (e.g. fans and / or pumps with high inertia and fast dynamics) you should disable the PID to stabilize the system. p099 - RESTORE DEFAULT - The inverter can be returned to the original factory configuration with this parameter. Richiamo dei parametri di default: press key M on the ALS-01 keyboard until P001 is visualized; press key (the display will visualize P099 ); press key "E" (the display will visualize 00 ); press key to bring the visualization to 01 then press "E" to memorize.

28 4.4 - CONFIGURATION EXAMPLES "Multispeed" mode S011 = 5 In this mode, the combination of inputs IN3 and IN4 allows you to select up to 4 different speeds (as shown in the "F" parameters table on par. 4.3). The speeds can be fixed, in which case the pairs of parameters (F001-F002; F003- F004; F005-F006 and F007-F008) must be set at the same value, i.e. at the required frequency for that speed selection. Alternatively, you can obtain speeds that comply with the analogue reference as well (within the limits set by parameters F017 F020); in this case, the above parameter pairs respectively define the maximum and minimum frequency limits for each speed selection. The frequency limits that can be set are in any case determined by parameters S001 and S002. The acceleration and deceleration ramps for each speed can also be individually set with parameters F009 - F016. Configuration example: Let's suppose we want to operate the motor with the following four speed pre-selections: Speed 1 = variable between 10 and 50Hz Speed 2 = 100 Hz Speed 3 = 40 Hz Speed 4 = 5 Hz The parameters to be set, starting from the default parameters (called up if necessary by setting P099 =1), are the following: Example of a speed profile and input status: S001 = 100 S011 = 5 F001 = 50 F002 = 10 F003 = 100 F004 = 100 F005 = 40 F006 = 40 F007 = 5 F008 = 5 I3=0; I4=0 Vel.1 I3=1; I4=0 Vel.2 I3=0; I4=1 Vel.3 I3=1; I4=1 Vel.4 All the speeds have a mirror-like equivalent in relation to the horizontal axis (negative frequency); this can be obtained by activating input 1 ("REV" function). S011 = 8 In this mode, inputs IN1 and IN2 can be combined with two speeds in one rotation direction, and inputs IN3 and IN4 can be combined with two speeds in the opposite direction. In this case too, the speeds can be fixed (by setting the same value for each "maximum frequency-minimum frequency" pair) or may vary on the basis of the reference source set in parameters F017 - F020.

29 In this mode, each input is associated with a frequency that the motor will reach once the relevant input has been activated. If several inputs are activated simultaneously however, the associated frequencies are added together until the maximum frequency set in parameter S001 is reached.

The diagram above shows a typical command input connection. The end stop sensors are of the PNP normally open type. They must be appropriately activated by a cam when the axis reaches its maximum stroke point. The inverter feeds the sensors (15 Vdc voltage between 8.C and 9.1, with positive on 8.C). The motor speed is adjusted by analogue input 1 (potentiometer or reference on terminal block No 9, as described on par 3.2.1). By activating the "START" input, the motor will start up in the "FWD" direction. Movement will continue until input 8.3 is activated. On the front of that input, the movement direction will be changed to "REV" (with deceleration and acceleration ramps programmed via parameters S003 and S004). When input 8.4 is activated, its front will bring the movement direction back to "FWD". And so on... The motor can be stopped at any time by deactivating the "START" input (obtaining a deceleration due to inertia or in the ramp, as per parameter P003 on par. 4.3). By activating the "STOP IN PHASE" input, the motor will stop moving with the next activation of either input IN3 (terminal 8.3) or input IN4 (terminal 8.4). In this situation, you can deactivate the "START" input and end the positioning cycle or deactivate the "STOP IN PHASE" input again in order to restart in the opposite direction. The activation of the START input while one of the two end stop inputs is already active causes the motor to move in the "opposite" direction. The delay on the sensor signal acquisition is usually about 150 ms. If the inversion signal comes from two potential-free contacts (buttons or relays rather than PNP sensors), just connect the two end stop contacts like the START command contact. NERIDRIVE Small (Rev07) pag. 29

30 "START/STOP with self-hold" operating mode S011 = 12 ) Operating principle: The REV input must be maintained in order to invert the motor direction. The START input is acquired on the impulse front (filtering 100 ms). The inverter only starts up if the STOP input is active. It is therefore an impulse with a self-hold circuit inside the inverter. 8.1 = REV 8.2 = START (n.a.) 8.3 = STOP (n.c.) 8.4 = "jog movement" When the STOP contact opens (on the opening front, filtering 100 ms), the motor stops on the ramp. If "jog movement" is closed: and the inverter is operating, there is a stop on the ramp; and the inverter is idle, the activation of START does not cause the self-hold of the movement command ("jog movement" mode, in which the motor only turns if the START key is kept pressed). Attention: in any case, if STOP is open, it prevails over any possible START command so the motor will not start up (either in self-hold or jog). pag. 30 NERIDRIVE Small (Rev07)

31 5 - DIAGNOSTICS AND TROUBLESHOOTING PROTECTION DEVICE INTERVENTION The intervention of any inverter protection device causes the motor to stop. If the ALS-01 terminal is connected, the following information can be visualised: the number of errors occurring on each protection device; the codes of the last five errors. The "error in progress" condition and the error codes can also be acquired via Modbus (see the related Manual for all the details). The inverter output suitably programmed, allows any current errors (or the ABSENCE of errors) to be signalled to external devices. The output function can only be programmed in relation to the error condition itself; no information about the type (code) of error can be obtained via the digital outputs. The protection devices in the inverter are: Overtemperature: triggered when the temperature of the power module exceeds 80 C. If it is triggered, make sure the inverter motor is installed in a place with enough air flow to cool the outer container of the inverter. Attention: this protection device is not linked to the motor temperature (that can be controlled by means of an optional thermoswitch fitted on at least one motor winding). Excellent thermal motor protection is already guaranteed by the cos control however (see the explanation of the relative protection device below). Overcurrent: triggered in the event of an instantaneous output overcurrent (on the motor). It can be triggered also during particular conditions having low supply voltage and heavy mechanical loads. Overvoltage: triggered when the voltage to the capacitor heads rises above the maximum permitted value. This condition may arise when sharp decelerations are applied with highly inertial loads. In this case, you must increase the deceleration time (via parameter S004). It may also occur if the supply voltage is above the 264 V limit so, if it is continually triggered, you should check whether the error intervenes during a motor deceleration or when the motor is idle or at a constant speed. By evaluating these conditions, you can accurately identify the reason for the intervention of the device. Cos protection: linked to the true power factor measurement that the inverter makes on the motor moment by moment. The standard parameters that the inverter uses to make the calculation (cos 0.8 and integration time 8 minutes = 480 seconds) guarantee extremely effective protection against motor overheating in any working conditions. Any modification of parameters P010 and P011 is not generally recommended for resolving problems linked to the repeated intervention of this protection device; such problems must be resolved by ensuring auxiliary ventilation on the motor, as otherwise the motor itself could burn.

32 5.2 - VISUALIZING THE ERRORS AND PROTECTION DEVICES By connecting the ALS-1 terminal (see paragraph 4.2) to the inverter motor in lockout, you can check the error code and, thanks to the information in the paragraph above, identify the type of protection device that has been triggered. If the inverter motor has already been cut off from the power supply, you can still access the memory of the last five errors once the ALS-1 terminal is connected. If the "auto restart" function is enabled after an error (parameter P013 not at 0), every intervention of a protection device is memorised. In parameter P014 you can programme the gap (in seconds) between the triggering of the protection device and the subsequent restart attempt. If the "auto restart" function is disabled (parameter P013 = 0), the motor can be restarted (after removing the cause of the protection intervention) with a new START command from the appropriate command input. Error codes (memorized in parameters from D101 to D105) Error code Display Description 1 ERR OT Power module overtemperature 2 ERR OL Overcurrent 3 ERR EF "External Fault" (emergency input activation) 4 ERR OV Overvoltage 5 ERR pf Motor thermal protection due to cos greater than P010 value for a period longer than 5 times P ERR cl Internal error "Communication Line" 11 ERR cb Time-out for communication on RS ERR EP "External Protection" (redundant control on the EMERGENCY input activation, if present) RESETTING THE ERRORS AND PROTECTION DEVICES pag. 32 NERIDRIVE Small (Rev07)

33 Motor restart is always subject to removal of whatever caused the error. In addition, if parameter P013 = 0 the restart is only possible following a new "START" command; if you are in an operating mode that requires a constantly active start input (e.g. S011 = 4), you must deactivate and reactivate the start input in order to restart. If parameter P013 is set at a value between 1 and 200, the automatic restart function will be enabled. In this case, the programmed value is the number of auto-reset attempts before a definitive lockout. Parameter P014 is the gap (in seconds) between one auto-reset attempt and the next. See paragraph 4.3. The parameters from D100 to D105 contain a memory of the errors occurring. This memory can be reset via parameter P018 (par. 4.3). NERIDRIVE Small (Rev07) pag. 33

34 5.4 - TROUBLESHOOTING If the motoinverter does not run in the correct way while not manifesting any alarm condition, the following table will provide useful diagnostics. BEFORE ANY MAINTENANCE OR VERIFICATION OF DIAGNOSTICS ON THE INTERNAL PARTS OF MOTOINVERTER, MAKE SURE THE POWER IS INTERRUPTED! Simptom - Motoinverter does not switch on; - ALS-01 communication interrupted. - the motor does not run; - Motoinverter does not switch on; - ALS-01 communication OK. - motor runs by pulls - the motor tries to start but as soon as the speed tends to increase, stops - the motor vibrates - the motor speed present oscillation - low motor torque - low motor power - the motor runs correctly but the auxiliary cooling does not work - motor overheating - inverter overheating Fuse interrupted (rif. par ); Wrong supply voltage. Electronic board falut. Possible causes and possible remedies Protection intervention related to a cause that it has not been removed (check parameter d100 and following). Programming parameters incorrect (if you have a written the list of parameters, verify if they match with the parameters currently stored in the inverter, making a transaction "restore default" and re-set the parameters). Irregular mechanical load. Motor phase interrupted. Connection between inverter and motor incorrect. Motor windings damaged. Irregular mechanical load. Motor phase interrupted. Connection between inverter and motor incorrect. If the vibration occurs at low to medium speeds and when no load is connected to the motor shaft is not in the presence of any anomaly and the fault disappears as soon as a minimum load is applied to the motor shaft. If vibration occurs with mechanical load is connected, check that this is not unbalanced. The mechanical load is unbalanced or the load alternates braking / draggings. Contact our technical support to evaluate the application. If the fault is under 3 Hz or above 50 Hz, the conditions may be normal (outside of this range of values the torque can be lower than the nominal). Check the connection of the motor (which must be strictly 230 V, so delta connection in 230/400 V motors). Contact our technical support to have assistance about the assessment of the working conditions. If the fault is under 50 Hz everything may be normal (if the speed is lower than the rated speed, the power is proportionally decreasing with the speed decreasing). If the fault occurs at the rated speed and is available the terminal ALS-01, check the electrical parameters: d001, d004, d005, d007, D008. Auxiliary fan failure, check the windings of the fan, verify that the auxiliary fan is designed for a power supply suitable to the voltage supplied by the inverter. Check that the motor is not overloaded (including whether it would match with the inverter, which could be oversized). A possible excessive heating of the ventilated motor in "IC01" may be due to a too low speed (below 1000 rpm self-ventilation may not be sufficient to adequately cool the engine). Consider to use a power cooling solution. If no temperature faults on the power inverter module occours (code 01 in the alarm memory from "d101" to "d105"), the temperature of the heat sink motoinverter should not worry as non-hazardous for motoinverter same. If the heat sink can be dangerous for any direct contacts by the User and it is essential that appropriate shielding insulation, take care not to prevent the regular heat dissipation necessary for the proper operation of the inverter. pag. 34 NERIDRIVE Small (Rev07)
