During the dEb deceleration (includes 0 Hz run), if the power recovers to a voltage higher than dEb return level, the
drive maintains the frequency for three seconds and then accelerates again. The “dEb” warning on the keypad is
automatically cleared.

Situation 3: Unexpected power shut down or power loss
Pr.07-13 = 1 and power does not recover
The keypad displays the “dEb” warning and the drive stops after decelerating to the lowest operating frequency.
When the DC bus voltage is lower than the Lv level, the drive disconnects the soft start relay until the power
completely runs out.
