Built-in PID: Simplify the establishment of a closed-loop control system
Automatic voltage regulation (AVR): Keep the output voltage in stable when the grid voltage fluctuates.
Stall prevention from overvoltage and overcurrent: The current and voltage are limited automatically during operation to prevent frequent tripping due to over-current and over-voltage.
Rapid current limit: Reduce the risk of over-current faults to keep VFD operated normally.
Torque limit and control: Limit the torque automatically during operation to prevent frequent tripping due to over-current.
Braking unit: Built-in braking unit for 18.5KW and below models

SPECIAL FEATURES
Deceleration to stop: In case of power loss, the energy from load feedback is used to compensate and decelerate the motor until standstill, to prevent mechanical damage.
