 0: The drive decelerates or stops based on the original deceleration time settings. Use this
setting when brake resistors are used.
 1: During deceleration, the drive controls the motor according to Pr.06-01 (Over-voltage Stall
Prevention) setting and the regenerative DC bus voltage. When the regenerative DC bus voltage
reaches 95% of Pr.06-01, the controller is enabled. If Pr.06-01=0, the drive controls on the basis
of the working voltage and regenerative DC bus voltage instead. When using this method, the
drive decelerates according to the deceleration time setting. However, the actual deceleration
time is equal to or larger than the deceleration setting time.
 2: During deceleration, the drive controls the motor according Pr.06-01 (Over-voltage Stall
Prevention) setting and the regenerative DC bus voltage. When the regenerative DC bus voltage
reaches 95% of Pr.06-01, the drive dynamically adjusts the output frequency and output voltage
to consume the regenerative energy. Use this method when the deceleration time that is set to
fulfill the system requirement for application triggers over-voltage.
 3: During operation (acceleration / steady speed / deceleration), the drive adjusts the output
voltage according to the amount of regenerative energy and consumes the regenerative energy
timely to reduce the risk of over-voltage. Moreover, you can also use Pr.01-50 (Electromagnetic
Traction Energy Consumption Coefficient) to adjust the drive’s output voltage strength.
 If you use the electromagnetic energy traction control (Pr.01-49=3) during linear deceleration (no
triggering of over-voltage stall prevention), you can enhance the output current by increasing the
output voltage (V
out
) to further suppress the regenerative DC bus voltage that is prompt to rise.
Using this function with Pr.06-02=1 (Smart Over-voltage Stall Prevention) can achieve a smoother
and faster deceleration.
