Simple PLC and

multi-speed operation

It implements up to 16 speeds via the simple PLC function or combination of DI terminal states.

Onboard PID

It realizes process-controlled closed loop control system easily.

Automatic 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.

Quick current limiting

Maximize overcurrent failure and protect the frequency converter in normal operation

Torque limit and

control

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

Torque control can be implemented in the CLVC mode.

Individualized functions

High performance

Control of asynchronous motor and synchronous motor are implemented through the high-performance current vector control technology.

Power dip ride

through

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
