Sets the time constant used to reduce the
output frequency during speed search. Related
to a change from max. output frequency to 0.
Delays the speed search operation after a
momentary power loss to allow time for an
external output contactor to close.
Sets the current injected to the motor at the
beginning of Esitmation type Speed Search.
Set as a factor to the motor rated current.
Sets the gain which is applied to the speed
detected by Speed Estimation Speed Search
before the motor is reaccelerated.Increase this
setting if OV occurs when performing speed
search.
Selects if Speed Search detects the motor
rotation direction during speed search.
0: Disabled–Frequency reference direction
used
1: Enabled–Detected direction used
Sets the speed search restart current level in
percentag of the drive rated current.
