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.
(has applied on high-speed spindle)
Status 1: Insufficient power supply due to momentary power-loss/unstable power (due to low
voltage)/sudden heavy-load

Status 2: unexpected power off, such as momentary power loss
The level for soft start relay to be ON
(Lv+30)
DE B function is activated
NOTE
For example, in textile machinery, you will hope that all the machines can be decelerated to stop to prevent broken stitching
when power loss. In this case, the host controller will send a message to the AC motor drive to use dEb function with
deceleration time via EF.
