Automatic voltage regulation (AVR function)

Keep output voltage constant automatically when input voltage fluctuating

Over-voltage & over-current stall control

Limit current & voltage automatically during the running process, prevent frequent over-current &    over-voltage tripping

Fast current limit function

Fast current limit, to make frequency    inverter works normally.

Torque limit and control

“Rooter” characteristics, limit the torque automatically and prevent frequent over-current tripping during the running process.

Under FVC control model, it can realize torque control.

Featured functions

Excellent control performance

Control the synchronous and asynchronous motor based on the high performance current vector control technology.
