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. (for high-speed axis application)
Status 1: Insufficient power supply due to momentary power-loss/unstable power (due to low
voltage)/sudden heavy-load

When Pr.07-14 is set to 0, the AC motor drive will be stopped and won't re-start
at the power-on again.
Status 2: unexpected power off, such as momentary power loss
