    V/F separation 2 ways: full separation, semi-separation
Torque boost Manual setting: 0.0~30.0% of rated output Automatic lifting: automatically determine the lifting torque according to the output current and combined with the motor parameters
Automatic current limiting and pressure limiting Whether during acceleration, deceleration or stable operation, it can automatically detect the motor stator current and voltage, and suppress it within the allowable range based on a unique algorithm to minimize the possibility of system fault tripping.
Control characteristics Inductive vector control Voltage frequency
characteristics		 Automatically adjust the output voltage-to-frequency ratio based on motor parameters and unique algorithm
Torque characteristics Starting torque:
150% rated torque at 3.0Hz (V/F control) 150% rated torque at 0.5Hz (vector control

Self-determination of motor parameters Without any restrictions, automatic parameter detection can be completed under both static and dynamic conditions of the motor to obtain the best control effect.
Current and voltage Full current closed-loop control, completely
    suppression avoiding current impact, with complete overcurrent and overvoltage suppression functions
Under voltage suppression
during
operation		 Especially for users with low grid voltage and frequent fluctuations in grid voltage, even if the voltage is lower than the allowed voltage range, the system can maintain the longest possible operating time based on a unique algorithm and residual energy allocation strategy.

Analog output 2 analog signal outputs, the output range can beflexiblysetbetween0~20mAor0~10V,which can realize the output of physical quantities such as set frequency and output frequency.
Automatic voltage stabilization operation You can choose dynamic voltage stabilization, static voltage stabilization, or unstabilized voltage according to your needs to obtain the most stable operating effect.
Acceleration and deceleration time setting 0.0s~6500.0s can be set continuously, S-shaped and linear modes are
optional
