PLC,Multiple preset speeds

It implements up to 16 speeds via the simple PLC function or by input(X) terminal states

Built-in PID

It realizes process-controlled closed loop control system easily.

Auto voltage
regulation (AVR)

It can keep constant output voltage automatically when the mains voltage changes.

Over-voltage/
Over-current stall
control

The current and voltage are limited automatically during the running process so as to avoid frequent tripping due to over-voltage/over-current.

Torque limit and
control

It can limit the torque automatically and prevent frequent over-current tripping during the running process.

High performance

Control of asynchronous motor is implemented through the high-performance current vector control technology

Instantaneous blackout doesn’t stop

The load feedback energy compensates the voltage reduction so that the AC drive can continue to run for a
short time.

Rapid current limit

It helps to avoid frequent over-current faults of the AC drive.

Timing control

Time range: 0.0–6500.0 minutes
