Onboard multiple preset speeds

It impements up to 16 speeds via the simple plc function or combination of rerminal states

Onboard 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.

Overvoltage/overcurrent stall control

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

Torque limit and control

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

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.

High performance

Control of asynchronous motoris implemented through the high-performance current vector control technology.

Timing control

Time range: 0.0-6500.0 minutes

Communication methods

RS485 (MODBUS-RTU)

Protection mode
