Adjust this parameter in these conditions:
• If there is resonance or hunting when you use the overvoltage suppression function, increase the setting value.
• If motor response is low when you use the overvoltage suppression function, decrease the setting value in 0.05-
unit increments.

Note:
• If n8-74 > n8-75 [Medium Load Iq Level (low)], the drive will detect oPE08 [Parameter Selection Error].
• The change is linear between n8-74 and n8-75 and the level of the pull-in current from n8-48 to n8-78 [Medium Load Id Current].

V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the proportional gain for output voltage control. Usually it is not necessary to change this
setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the gain of internal speed feedback detection suppression while the overvoltage suppression
function is operating as a magnification value. Usually it is not necessary to change this
parameter.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Usually it is not necessary to change this setting. Sets the Proportional gain that the drive uses for
speed estimation.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Selects the speed estimation method. Usually it is not necessary to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Set n8-48 [Pull-in/Light Load Id Current] to the percentage of load current (q-axis current) that
you will apply, where E5-03 [Motor Rated Current (FLA)] = a setting value of 100%.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Set n8-78 [Medium Load Id Current] to the percentage of load current (q-axis current) that you
will apply, where E5-03 [Motor Rated Current (FLA)] = a setting value of 100%.
