Control character

V/F Curve (Voltage-Frequency character)

Base frequency can be set from 5~500Hz arbitrarily, and there are three kinds of curve: constant torque, Dec torque 1 and Dec torque 2.

Torque Boost

Manual Setting: 0~20% of rated output, Auto-boost: Automatically boost

torque according to output current.

Auto Energy-saving running

Adjust output voltage and slip

compensation properly according to output current, which will make the motor working in highest efficiency.

Acc./Dec time setting

0.1~6000 seconds can be set continuously, and S type and line type can be selected

Dynamic braking

Over 75% (External the braking resistor)

DC braking

It is selected respectively at start and stop, and its frequency is 0~15Hz, the action voltage is 0~15%, and the action time is 0~20.0 second or act continuously

Auto current-limiting function

Fast auto current-limiting function ensures not to occur the over-current during the accelerate process or under the impact load.

Voltage stall prevention

Ensure not over-voltage in Dec process.

Low noise running

Carrier freq. can be adjusted continuously form 1.5KHz to 15.0KHz, which can reduce the motor’s noise furthest.

Speed tracking restart

It can realize the smoothness restart and instantaneous stop then restart function.

Freq setting signal

Analog input

DC voltage 0~10V,-10V~10V, DC current 0~20mA ( Upper limit and Lower limit can be selected )

Digital setting

Pulse input

0~10kHz (Upper limit and Lower limit can be selected)

Startup signal

FWD, REV, Startup signal can be selected and self-keep (Three line control)

Timer and Counter

Embedded one timer and one counter, which will help the system’s integration

Multi-speed control function / Wobble frequency

Seven stages programmable multi-speed control at most, every stage’s running direction, running time can be set respectively. In external terminal control, It reaches 15 stages, and there are 6 kind of running modes. Including wobble frequency

Embedded PID control

Ordinal PID

Expediently compose the simple control system without accessional PID controller.

Special for water supply (Need accessories)

Be able to construct the constant-pressure water-supply system of 4 pumps switch at
