
3 (auto-acceleration and deceleration-decelerate by actual load): the drive auto-detects the load
torque and accelerates from the fastest acceleration time and smoothest start current to the
setting frequency. When decelerating, the drive auto-detects the load re-generation and stops the
motor smoothly with the fastest deceleration time.

4 (stall prevention by auto-acceleration and deceleration –refer to acceleration and deceleration
time): if the acceleration and deceleration is within a reasonable range, the drive accelerates and
decelerates according to Pr.01-12–01-19. If the acceleration and deceleration time is too short,
the actual acceleration and deceleration time are greater than the acceleration and deceleration
time settings.

Use this to set the time to decelerate from the maximum operation frequency (Pr.01-00) to 0.00
Hz by CANopen control.
Regenerative Energy Restriction Control Method
Default: 0
Settings 0: Disable
1: Over voltage energy restriction
2: Traction energy control (TEC)

0: decelerate or stop in accordance with the original deceleration setting.

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.
