This parameter shall set Max allowable time for power loss in case of momentary power loss and if function of
Restart after momentary power failure is started. If power supply breaking time exceeds Max allowable time, output
of AC inverter shall stop after power resupplied.

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 inverter
starting.When setting external B.B and restart after alarm, this parameter shall be time for speed tracking.

Parameters above define inhibited frequency setting, and this range shall be avoided from frequency setting for
inverter, 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.
