Acceleration/ deceleration time Acceleration/deceleration pattern: Linear acceleration/deceleration, S-curve acceleration/deceleration (weak, arbitrary (with function code)), curvilinear acceleration/deceleration Deceleration mode (coast-to-stop): Shutoff of the run command lets the motor coast to a stop. Acceleration/deceleration time exclusive to jogging (0.00 to 6000 s) Forcible stop deceleration time: Deceleration stop by the forcible stop STOP. During forced stop operation, S-curve acceleration/deceleration is disabled. Frequency limiter(Upper limit and lower limit frequencies) • Specifies the upper and lower limits in Hz. • “Continue to run” or “Decelerate to a stop” selectable when the reference frequency drops below the lower limit. Frequency/PID command bias • Bias of reference frequency and PID command can be independently set (setting range: 0 to ±100%). Analog input • Gain: Setting range from 0 to 200% • Offset: Setting range from -5.0 to +5.0% • Filter: Setting range from 0.00 s to 5.00 s • Polarity selection (±/+) Jump frequency • Three operation points and their common jump width (0 to 30.0 Hz) can be set. Timed operation The inverter drives the motor for the run time specified from the keypad and stops its output. (Single-cycle operation) Jogging operation • Operation with key (standard keypad), or key (multi-function keypad), or digital input signal FWD or REV (Exclusive acceleration/deceleration time setting, exclusive frequency setting) Auto-restart after momentary power failure • Trip immediately: Trip immediately at the time of power failure. •Trip after a recovery from power failure: Coast to a stop at the time of power failure and trip when the power is recovered. •Trip after decelerate-to-stop: Deceleration stop at power failure, and trip after stoppage • Continue to run: Operation is continued using the load inertia energy. •S tart at the frequency selected before momentary power failure: Coast-to-stop at power failure and start after power recovery at the frequency selected before momentary stop. • Start at starting frequency: Coast-to-stop at power failure and start at the starting frequency after power recovery. •S tart at the frequency searched at the time of power recovery: Coast-to-stop at power failure, search for the idling motor speed, and restart the motor. Hardware current limiter Limits the current by hardware to prevent an overcurrent trip from being caused by fast load variation or momentary power failure, which cannot be covered by the software current limiter. This limiter can be canceled. Operation by commercial power supply With commercial power selection commands (SW50, SW60), the inverter outputs 50/60 Hz. Slip compensation • Compensates for decrease in speed according to the load • Possible to set constants for the response of slip compensation. Droop control •Decreases the speed according to the load torque. Control Torque limiter Torque current limiter Control output torque so that output torque is preset limiting value or less. • Switchable between 1st and 2nd torque limit values • Torque limit and Torque current limit are selectable. IMPG-VC • Torque limit by analog input. PM-SVC Software current limiter Automatically reduces the frequency so that the output current becomes lower than the preset operation level. This limiter can be canceled. Overload stop If the detected torque or current exceeds the preset value, the inverter decelerates the motor to a stop or causes the motor to coast to a stop. PID control • PID processor for process control/dancer control • Normal operation/inverse operation •PID command: Keypad, analog input (from terminals [12], [C1] (C1 function) and [C1] (V2 function)), multistep frequency (3 steps), RS-485 communication • PID feedback value: Analog input (from terminals [12], [C1] (C1 function) and [C1] (V2 function)) • Alarm output (absolute value alarm, deviation alarm) • Low liquid level stop function (pressurized operation possible before low liquid level stop) • Anti-reset wind-up function • PID output limiter • Integration reset/hold Auto search for idling motor speed The inverter automatically searches for the idling motor speed and starts to drive it without stopping it. Motor parameters require tuning. (Offline tuning) Automatic deceleration • If the DC link bus voltage or calculated torque exceeds the automatic deceleration level during deceleration, the inverter automatically prolongs the deceleration time to avoid overvoltage trip. (It is possible to select forcible deceleration actuated when the deceleration time becomes three times longer.) •If the calculated torque exceeds automatic deceleration level during constant speed operation, the inverter avoids overvoltage trip by increasing the frequency. 5 COMMON SPECIFICATIONS Item Control Display Explanation Remarks Deceleration characteristic (improved braking capacity) The motor loss is increased during deceleration to reduce the regenerative energy in the inverter to avoid overvoltage trip. Auto energy saving operation Controls the output voltage to minimize the total sum of the motor loss and inverter loss. Overload prevention control If the surrounding temperature or IGBT junction temperature increases due to overload, the inverter lowers the output frequency to avoid overload. Battery/UPS operation Cancels the undervoltage protection so that the inverter under an undervoltage condition runs the motor with battery/UPS power. Offline tuning Tunes the motor while the motor is stopped or running, for setting up motor parameters. Online tuning Controls the motor speed variation caused by the motor temperature rise during running. Cooling fan ON/OFF control • Detects inverter internal temperature and stops cooling fan when the temperature is low. • Possible to output a fan control signal to an external device. 1st to 2nd motor settings • Switchable between two motors It is possible to set the base frequency, rated current, torque boost, and electronic thermal slip compensation as the data for 1st and 2nd motors. Universal DI Transfers the status of an external digital signal connected with the general-purpose digital input terminal to the host controller. Universal DO Outputs a digital command signal sent from the host controller to the general-purpose digital output terminal. Universal AO Outputs an analog command signal sent from the host controller to the analog output terminal. Speed control • Notch filter for vibration control • Selectable among the four set of the auto speed regulator (ASR) parameters. (a PG option card is required.) IMPG-VC PM-SVC Line speed control In a machine such as winder/unwinder, regulates the motor speed to keep the peripheral speed of the spool constant. (a PG option card is required.) IMPG-VF Positioning control with pulse counter The positioning control starts from the preset start point and counts the feedback pulses by means of PG card installed in the inverter. The motor can be automatically started decelerating to the creep speed at which the target position can be detected, so that the motor can stop near the position (a PG option card is required). Excluded IMPG-VC PM-SVC Master-follower operation Enables synchronous operation of two motors equipped with a pulse generator (PG). (a PG option card is required.)
