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
Deceleration stop (can be superimposed DC braking); free to stop
