NOTE

DC BUS voltage

it doesn't need

multi-function terminals

The level for DEB return time

(Lv=+30V+58V)

Lv level

Soft start relay at

power side

Output frequency

DEB return time

Pr.07-13 Decel. time selection for

momentary power loss

DEB function is activated

The level for soft start relay to be ON

(Lv+30)

When Pr.07-14 is set to 0, the AC motor drive will be stopped and wo n't re-start

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.
