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

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.
