NO
DCBUS voltage

Soft start relay
at power side

activated
dEb return time
Pr07-13 Decel. time at momentary
power loss (dEb function)
Level for soft start relay to be ON
0Hz
07-14
Output frequency
Note (1)When Pr.07-14 is set to 0, the motor drive will stop and will not accelerate to the frequency before dEb even
the power is on again. But when Pr07-14 is NOT set to 0, then a command of zero speed will be sent to wait for
power on.
Note (2) dEb activation level is when DCBUS voltage level lower than (230V series : Lv level +20Vdc)
(460V series: Lv level +40Vdc)
Status 2: unexpected power off, such as momentary power loss
DCBUS voltage
Lv level
Soft start relay

Output frequency
dEb return time
Pr.07-13 Decel. time selection at
momentary power loss
dEb function activated
Level for soft start relay to be ON
07-14
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.
