Settings
0: Normal deceleration
1: Over voltage energy restriction
2: Traction energy control (TEC)
 0: decelerate or stop in accordance with the original deceleration setting.
 The actual deceleration time of the motor is higher than the deceleration time setting due to the
over-voltage stall prevention.
 1: during deceleration, the drive controls the motor according to the setting of Pr.06-01 and the
voltage recovery rate 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 voltage recovery rate 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 of Pr.06-01 and the
voltage recovery rate of the DC bus. 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 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.
