characteristic)
Three ways: the first is linear torque characteristic curve, the second is square
torque characteristic curve, and the third is user-set V/F curve
Torque boost
Manual setting: 0.0
~
30.0% of rated output
Automatic lifting: automatically determine the boost torque according to the
output current and motor parameters
Automatic current
and voltage
limiting
Whether in acceleration, deceleration or stable operation, the motor stator
current and voltage can be automatically detected, which can be suppressed
within the allowable range according to the unique algorithm to minimize the
possibility of system fault tripping
Sensorless vector

Current and
voltage
suppression
Full-range current closed-loop control, completely avoiding current impact,
with perfect overcurrent and overvoltage suppression function
Undervoltage
suppression during
operation
Especially for users with low grid voltage and frequent fluctuation of grid voltage, the system can
maintain the longest possible operation time according to the unique algorithm and residual energy
allocation strategy even in the range below the allowable voltage
