Output Frequency  Range


Control Mode

V/F Control, Sensor less Vector Control

Starting Torque

0.5Hz/150%(SVC), 1Hz/150%(V/F);

Communication Port

RS-485, which support MODBUS protocol (optional)


Less than 5.9m/s

Fault Protection

protect from over current, over voltage, under voltage, over temperature, phase failure, over load etc.


















Basic Function


Over load capability

G type:150% rated current 60s;180% rated current 3s

Torque boost

Auto torque boost function; Manual torque boost 0.1%~30.0%

V/F curve

Linear V/F, multi-point V/F and square V/F curve(power of 1.2,1.4,1.6,1.8,2)

V/F separation

2 ways: separation and semi-separation



Acc./dec curve

Straight line or S curve acceleration and deceleration mode,

Four kinds of acceleration and deceleration time. Acceleration and deceleration time range from 0.0s to 6500.0s


DC braking

DC braking frequency:0.00Hz to maximum frequency. Braking time:0.0s to 36.0s

Brake current value:0%-100%


Jog control

Jog frequency range:0.00Hz~50.00Hz;

Jog acceleration/deceleration:0.0s~6500.0s.

Simple PLC

It can realize at maximum of 16 segments speed










    Basic Function

Multiple segment speed running

Running via the built-in PLC or control terminal.

Built-in PID

It is easy to realize process-controlled closed loop control system.

Auto voltage regulation (AVR)

It can keep constant output voltage automatically in the case of change of network voltage.

Over-voltage/current stall control

It can limit the running voltage/current automatically and prevent frequent over-voltage/current tripping during the running

Quick current limit

Minimize the over-current fault, protect normal operation of the AC Drive.

Torque limit & control

"Excavators" characteristics, automatically limit torque during operation, prevent frequent over-current tripping. Closed loop
vector mode can realize the torque control.



Personalized Function

Instantaneous stop non-stop

When instantaneous power off, voltage reduction is compensated through load feedback energy, which could make AC Drive keep
running in a short period of time.

Rapid current limit

To avoid AC Drive frequent over-current fault.

Timing control

Timing control function :set time range 0Min~6500.0Min.

Keyboard Operation

Keyboard potentiometer

Equipped with keyboard potentiometer or coding potentiometer.


Keyboard Operation


Protection function

It can implement power-on motor short-circuit detection, input /output phase loss protection, over current protection, over
voltage protection, under voltage protection, overheating protection and overload protection.
