Sine wave PWM (V/f control, sensorless current vector control)
Heavy duty use: 150% rated output current for one minute
Normal duty use: 120% rated output current for one minute
Short-term average deceleration torque: 150% (up 1.5 kW), 100% (for 1.5 kW), 50% (for 2.2 kW), 20% (fof bigger size)
Continous regenerative torque: Aprox 20% (125% with optional braking resistor, 10%ED, 10 s, braking transistor built itn)
Seven of the following input signals are selectable: Forward/reverse run (3-wire sequence), fault reset, external fault (NO/NC
contact input), multi-step speed operation, Jog command, accel/decel time select, external baseblock, speed search com-
mand, UP/DOWN command, accel/decel hold command, LOCAL/REMOTE selection, communication/control circuit terminal
selection, mergency stop fault, emergency stop alarm, self test
Following output signals are selectable (NO/NC contact output, 2 photo-coupler outputs): Fault, running, zero speed, speed
agree, frequency detection (output frequency <= or => set value), during overtorque detection, minor error, during baseblock,
operation mode, inverter run ready, during fault retry, during undervoltage detection, reverse running, during speed search,
Open-loop vector control, full-range automatic torque boost, slip compensation, 17-step speed operation (max.), restart after
momentary power loss, DC injection braking current at stop/start (50% of inverter rated current, 0.5 sec, or less), frequency
reference bias/gain, MEMOBUS communications (RS-485/422, max. 115K bps), fault retry, speed search, frequency upper/
lower limit setting, overtorque detection, frequency jump, accel/decel time switch, accel/decel prohibited, S-curve accel/decel,
Motor coasts to a stop at approx. 250% of inverter rated current
Heavy Duty: Motor coasts to a stop after 1 minute at 150% of inverter rated output current
Normal Duty: Motor coasts to a stop after 1 minute at 120% of inverter rated output current
Motor coasts to a stop if DC bus voltage exceed 410 V (double for 400 V class)
Stops when DC bus voltage is approx. 190 V or less (double for 400 V class)
Following items are selectable: not provided (stop if power loss is 15 ms or longer), continuous operation if power loss is
Stall prevention during acceleration/deceleration and constant speed operation
Protected by electronic circuit (operation level is approx. 250% of rated output current)
