2 methods: full separation, semi-separation

Torque boost

Manual setting: 0.0～30.0% of rated output

Automatic boost: Automatically determine the boost torque based on the output current and motor parameters

Automatic current and voltage limiting

Whether in acceleration, deceleration or stable operation, it can automatically detect the motor stator current and voltage, and suppress them within the allowable range based on a unique algorithm, minimizing the possibility of system fault tripping.

Control characteristics

Sensorless vector control

Voltage frequency characteristics

Automatically adjust the output voltage-frequency ratio according to motor parameters and unique algorithm

Torque characteristics

Starting torque:

150% rated torque at 3.0Hz (V/F control)

150% rated torque at 0.5Hz (speed sensorless vector control)

Operating speed steady-state accuracy: ≤±0.2% rated synchronous speed

Speed fluctuation: ≤±0.5% rated synchronous speed

Torque response: ≤20ms (speed sensorless vector control)

Motor parameter self-determination

Without any restrictions, the automatic detection of parameters can be completed in both static and dynamic conditions of the motor to obtain the best control effect

Current and voltage suppression

Full current closed-loop control, completely avoiding current shock, with perfect over-current and over-voltage suppression function

Undervoltage suppression during operation

Especially for users with low grid voltage or frequent grid voltage fluctuations, the system can maintain the longest possible operating time based on unique algorithms and residual energy allocation strategies even when the voltage is below the allowable range.

Analog Output

2 analog signal output, the output range is flexibly set between 0~20mA or 0~10V, which can realize the output of physical quantities such as set frequency and output frequency

Automatic voltage stabilization operation

According to the needs, you can choose dynamic voltage stabilization, static voltage stabilization, and non-stabilization to obtain the most stable operation effect.

Low noise operation

The carrier frequency is continuously adjustable from 0.5KHz to 16.0KHz to minimize motor noise

Speed tracking speed

Restart function

It can realize the smooth restart and instantaneous stop restart function of the running motor

Counter

One internal counter for easy system integration

Run function

Upper and lower frequency limit setting, frequency jump operation, reverse operation limit, slip frequency compensation, RS485 communication, frequency increase and decrease control, fault self-recovery operation, etc.

Alarm content
