Abnormal condition: DC bus > Pr.06-01 Over-voltage stall prevention
1. Pr.06-02 = 0:
During deceleration, the drive maintains the DC bus voltage and slowly decrease the output
frequency (which takes a long time to decelerate to 0 Hz).
2. Pr.06-02 = 1:
If you set Pr.06-01 to a small value that lower than the DC bus voltage, the drive maintains
the DC bus voltage and the output frequency during deceleration. To prevent this situation,
modify the Pr.06-01 setting to a value larger than the DC bus voltage (Pr.06-01 is able to be
set during operation).
