V / f curve type: straight line, multipoint, power function, V / f separation;

Torque boost support: Automatic torque boost (factory setting), manual torque boost

Support linear and S curve acceleration and deceleration;

4 groups of acceleration and deceleration time, setting range 0.00s ~ 60000s

Overvoltage stall control: limit the power generation of the motor by adjusting the output frequency to avoid skipping the voltage fault;

Undervoltage stall control: control the power consumption of the motor by adjusting the output frequency to avoid yaw failure

VdcMax Control: Limit the amount of power generated by the motor by adjusting the output frequency to avoid over-voltage trip;

VdcMin control: Control the power consumption of the motor by adjusting the output frequency, to avoid jump undervoltage fault
