SM5 6 3. TECHNICAL DATA 3.1 General Figure 3-1 show a block diagram of the SM5 inverter. Diode Bridge produces the DC voltage for the IGBT inverter Bridge block. The IGBT bridge produces a symmetrical three-phase PWM modulated AC voltage to the motor. The power drawn from the supply is almost entirely active power. The Motor Control block is based on microprocessor software. The microprocessor controls the motor according to measured signals, parameter value settings and commands from the Control I/O block and the Keypad. And it calculates the IGBT switching positions. Gate Drivers amplify these signals to drive the IGBT inverter bridge. The Keypad is a link between the user and the inverter. With the Keypad the user can set parameter values, read status data and give control commands. The Keypad is removable and can be mounted externally and connected via a cable to the inverter. The Control I/O block is isolated from the mains potential and is connected to earth via a 1MΩ resistor and 4.7nF capacitor.

27 SM5 7.3.4 Description of parameters 1.1 Minimum frequency Defines frequency minimum limits of the inverter. See figure 7-2. 1.2 Maximum frequency Defines frequency maximum limits of the inverter. See figure 7-2. 1.3 Acceleration time These limits correspond to the time required for the output frequency to accelerate from the set minimum frequency(par.1.1) to the set maximum frequency(par.1.2). See figure 7-2. 1.4 Deceleration time These limits correspond to the time required for the output frequency to decelerate from the set maximum frequency(par.1.2) to the set minimum frequency(par1.1). See figure 7-2. Hz Par.1.2 Par.1.1 Accel. time Par.1.3 Decel. time Par.1.4 t Figure 7-2 Parameters 1.1, 1.2, 1.3, 1.4 1.5 Jogging frequency This parameter value defines the jogging frequency selected with the JOG digital input which can be programmed for Jogging frequency. 1.6 Supply voltage Set the parameter value according to the nominal voltage of the supply. 1.7 Nominal voltage of the Motor Find this value from the rating plate of the motor. 1.8 Base Frequency Find this value from the rating plate of the motor. This parameter sets the field weakening point. See figure 7-3. 1.9 Slip Frequency This parameter sets the slip frequency of the motor.

SM5 28 1.10 Slip Compensation Delay time If the motor inertia is big, the stable operation can be done by increasing the filtering time of slip compensation at the starting moment. Increase this parameter value in accordance with the motor capacity, but too big value comparing motor capacity can be a reason of delayed response. 1.11 Slip Frequency Gain It is to restrain the motor hunting and the abnormal rising of output current that are created by an over slip-compensation. 1.12 Forward Torque Boost 1.13 Reverse Torque Boost It is a function to compensate the torque that is decreased by stator resistance of the motor in low speed at forward or reverse operation. And it compensates the constant value based on rated voltage. See figure 7-3. V (100% = Par.1. 22 ) Motor voltage Motor Torque Motor crrent Torque Boost Par.1.12 or Par.1.13 Par.1. 8 Figure 7-3 Voltage - frequency Hz 1.14 Power of the Inverter 1.15 Nominal current of the Motor Find the value from the rating plate of the motor. 1.16 Current limit This parameter determines the maximum motor current that the inverter can give momentarily. If the motor current is higher than Current limit(par.1.16) at the acceleration, then the acceleration stop until the motor current is down. 1.17 Stall current limit The motor stall protection protects the motor from short time overload situation like a stalled shaft. In the stall state, the current has to be above this limit. 1.18 Stall time This is the maximum allowed time for the stall state. 1.19 Stall frequency In the stall state, the output frequency has to be lower than this limit. 1.20 Overcurrent protection It protects inverter from the overcurrent.

29 SM5 1.21 Undervoltage protection It stops inverter when a DC link voltage is smaller than this parameter. (100% = Par.1.6 2 ) 1.22 Output Voltage scale This parameter adjusts the output voltage of the inverter at the base frequency(par.1.8).

Increasing the switching frequency reduce the capacity of the inverter. 1.24 No Load Current This parameter sets the no load current for using the function of slip control and auto torque boost.

When the slip control mode is applied, the related parameters are as follows. Par.1.9 Slip Frequency Par.1.10 Slip Compensation Delay time Par.1.11 Slip Frequency Gain Par.1.24 No Load Current 3.3 Auto Torque Boost The voltage of the motor is changed automatically to make the needed torque over the full range of the speed. The overheat of the motor could be occurred by a big torque at low speed. If auto torque boost is selected, Par.1.12(FWD Torque), Par.1.13(REV Torque) are changed automatically. If starting torque is insufficient, Par.1.12 and Par.1.13 should be increased by 0.1[%] unit, but too big value of this parameter could be the reasons of overcurrent and the hunting of the motor. 3.4 U/f Curve selection 0 Linear Curve (A) The voltage of the motor changes linearly with the frequency in the constant flux area from 0Hz to the base frequency(par.1.8). 1 Programmable Curve (B) The Programmable Curve can be used if the Linear Curve and Squared Curve do not satisfy the needs of the application. 2 Squared Curve (C) The voltage of the motor changes following a squared curve form with the frequency in the area from 0Hz to the base frequency(par.1.8).

F7 External fault Fault is detected from external fault digital input. Check the external fault circuit or device. F8 Undervoltage DC-link voltage has gone below set value(par1.21) of the nominal voltage. - Most common reason is failure of the mains supply. In case of temporary supply voltage break, reset the fault and start again. Check mains input. If mains supply is correct, an internal failure has occurred. F9 Stall Motor stall protection has tripped. - Check the motor. Table 7-6 Fault codes

39 SM5 7.4.2 Fault Scan When a fault occurs, the fault history mode becomes active. SM5 inverter stores maximum 9 faults in the order of occurrence. The latest fault is always designated 0 and the fault occurred right before the latest is designated 1. When 9 undeleted faults are stored in the memory, the newly occurred fault removes the oldest fault out of the memory. 7.4.3 Monitoring Number Data name Unit Description 1 F out Hz Frequency to the motor. 2 Current A Measured motor current. 3 DC vtg V Measured DC_link voltage. 4 V MOTOR V Calculated motor voltage. 5 DI status 6 DO status 7 V ref V Status of digital inputs as follow ; (0 = open input, 1= closed input ) status MS1 MS2 MS3 DI2 DI1 OFF 0 0 0 0 0 ON 1 1 1 1 1 Status of digital output and Relay 2 as follow ; status BR DO OFF 0 0 ON 1 1 Voltage of terminals V in and GND ref.

SM5 40 8. Vector Control Mode(Closed Loop) SM5 inverter can provide far more precise speed and torque control characteristics with the vector control mode than the inverter with the VVVF control mode since the magnetizing current and the torque current of the induction motor can be controlled independently to each other by the vector control mode. SM5 inverter has to be, for the application of the vector control mode, equipped with ; a ROM loaded with the vector control software and, an encoder of 5V DC line drive type for feed back of the motor speed to the inverter control. An encoder of 12V DC or 24V DC can also be applied with a separate power supply.
