Situation 4: Unexpected power shut down or power loss
Pr.07-13 = 2 and power does not recover
The drive decelerates to 0 Hz. The DC bus voltage continues to decrease until the voltage is lower than the Lv
level, and then the drive disconnects the soft start relay. The keypad displays “dEb” warning until the drive
completely runs out of power.
Situation 5: Pr.07-13 = 2 and power recovers after the DC bus voltage is lower than the Lv level.
