Set n8-57 = 1 [HFI Overlap Selection = Enabled] to enable this parameter. Increases the stability when the speed
or load suddenly change, for example with rapid acceleration/deceleration or impact loads.

V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the current level at which output voltage limit sequence selection occurs as a percentage
where the motor rated current is 100%. Normally there is no need to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the hysteresis width of the current level at which output voltage limit sequence selection
occurs as a percentage where the motor rated current is 100%. Normally there is no need to
change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the speed level at which output voltage limit sequence selection occurs as a percentage where
the maximum output frequency is 100%. Usually it is not necessary to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the limit value of feedback output voltage limit Id operation. Enabled when n8-87 = 0
[Output Voltage Control Selection = Speed Feedback Form]. Usually it is not necessary to change
this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the criteria that the drive uses to find changes in speed or load. Usually it is not necessary to
change this setting.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the time constant of the filter used for the recognition criteria value for speed and load
changes. Usually it is not necessary to change this setting.
