Main control function

Control mode

Space voltage vector PWM control ;

Sensorless vector control (SVC)

Frequency accuracy

Digital setting: Max frequency ×±0. 01%

Analog setting: Max frequency ×±0. 2%

Frequency resolution

Digital setting: 0.01Hz

Analog setting: Max frequency ×0.1%

Torque rise

Auto torque rise, manual torque rise 1%30.0%

V/F curve

Three ways Linear V/F curve, square V/F curve, user self-defining V/F curve

Acceleration/deceleration curve

Optional time unit (Min/s), the longest: 6000s (settable in the range of 0.13600s).

DC braking

Be optional during both starting and stopping, the operating frequency: 020Hz,operating voltage level: 020%,operating time: settable within 020s


Jogging frequency range: 0.1Hz50.00Hz,jogging acceleration and deceleration time: 0.13600s.

Built-in PID

It is convenient for forming closed loop control system, applicable for course control like pressure and flow, etc.

Multi-speed operating

Realize multi-speed running by built-in PLC or control terminal.

Weaving wobble frequency

Can get wobble frequency of adjustable central frequency

Auto voltage adjustment

When main voltage changes, the output voltage may be kept constant by adjusting PWM output (AVR function).

Auto energy-saving running

According to load condition, V/F curve can be optimized automatically to get the aim of energy-saving running.

Auto current limiting

Limit in-service current automatically, so as to avoid tripping for fault caused by frequent over current.

Sensorless vector control

Torsion characteristic

150% output of torque at 1Hz, rev accuracy: 0.1%

Motor parameters automatic read

Reading the parameters from motor when completely stop in order to achieve optimal controlling effect.

Running function

Running command passage

Setting of operating manual; setting of control terminal; setting of serial port; switching by three ways

Industrial and civilian use of the boiler blower,induced draft fan speed control air flow and heart transfer station urban heating circulation pump speed control temperature, central air-condition Circulating chilled water pumps, cooling water pump speed control temperature, ventilation underground coal mines,cement ceramic furnace Fan speed control and energy-saving equipment, dust,water plant pump to control pressure on the pipeline,a sewage traitment plant oxidation pond oxygen supply fan speed control,dyeing and finishing equipment ,recycled  water control, subway,complexes and large-scale workshops exhaust air control,Pressure water supply heating,air compressor,and so on Energy Saving.
