stopping.
N/A Saves energy by always operating the motor at its maximum efficiency.
Increases motor loss to allow for faster deceleration than normal without the
N/A use of dynamic braking options. The effectiveness may vary based on motor
characteristics.
Decelerates the drive to allow it to ride through a momentary power loss and

continue operation.
N/A Provides fast deceleration without using dynamic braking options.
Prevents overvoltage by increasing speed during regeneration. Never use
YES
this function with hoist or crane applications.
