● 0: decelerate or stop in accordance with the original deceleration setting.
● The actual deceleration time of the motor is longer than the deceleration time setting because of the over-
voltage stall prevention.
● 1: during deceleration, the drive controls the motor according to the setting for Pr.06-01 and the recovery
voltage of the DC bus. The controller starts when the DC bus voltage reaches 95% of Pr.06-01. When Pr.06-01
is set to 0, the drive controls the motor according to the operating voltage and the recovery voltage of the DC
bus. This method decelerates according to the setting for the deceleration time. The fastest actual deceleration
time is not less than the deceleration time setting.
● 2: during deceleration, the drive controls the motor according to the setting for Pr.06-01 and the DC bus
voltage. The controller starts when the DC bus voltage reaches 95% of Pr.06-01, auto-tunes the output
frequency and the output voltage to accelerate the consumption of the regenerative energy according to the
drive’s capability, and the deceleration time is the result of the drive’s auto-tuning. Use this setting when over-
voltage occurs due to unexpected deceleration time.
