Onboard multiple preset speeds

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

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 motor are implemented through the highperformance current vector control technology.

Timing control

Time range: 0.0–6500.0 minutes

Communication methods


Protection mode

Motor short-circuit detection at power-on, input/output phase loss protection, over current protection, overvoltage protection, under voltage protection, overheat protection and overload protection.

Input and output

Input terminal

6 digital input terminals, one of which supports up to 100 kHz high-speed pulse input.

2 analog input terminals, one of which only supports 0–10 V voltage input and the other supports 0–10 V voltage input or 4–20 mA current input.

Frequency source

Digital setting, analog voltage setting, analog current setting, pulse setting and serial communication port setting.

Auxiliary frequency source

There are ten auxiliary frequency sources.It can implement fine tuning of auxiliary frequency and frequency synthesis.

Running command source

You can perform switchover between these sources in various ways.
