The DEB (Deceleration Energy Backup) function is the AC motor drive decelerates to stop after momentary power loss. When the momentary power loss occurs, this function can be used for the motor to decelerate to 0 speed with deceleration stop method. When the power is on again, motor will run again after DEB return time.

Status 1: Insufficient power supply due to momentary power-loss/unstable power (due to low voltage)/sudden heavy-load
