If power supply interruption is detected, AC motor drive shall stop output and shall not be re-started
until after set time by this parameter. It’s preferred to provide output side residual voltage to be
approximately 0V prior to AC motor drive starting.
When setting external B.B and restart after fault, this parameter shall be time for speed tracking.

Parameters above define inhibited frequency setting, and this range shall be avoided from
frequency setting for AC motor drive, reason is that frequency output shall not be stable at these
ranges but shall stay beyond these ranges of frequency. However, since frequency output shall be
continuous, when frequency is not set within these ranges, frequency output shall be continuous
and jumping shall not occur at locations of inhibition frequency.

Fault restarting times
Factory setting
d 0
Setting range
d 0<->d 10
Times of auto restarting of AC motor drive shall be set to 10 times after fault (for fault allowable
situations: OC (over current) and OV (over voltage)). If it is set to 0, auto-reset/restarting function
shall not be performed. In restarting after fault, AC motor drive shall be started in speed tracking
mode up to down.
