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 CL-V/f OLV CLV AOLV
Sets the output voltage limit to prevent saturation of the output voltage.
Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
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 CL-V/f OLV CLV AOLV
Sets the gain that the drive uses for speed estimation. Usually it is not
necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Selects the speed estimation method. Usually it is not necessary to change
this setting.
V/f CL-V/f OLV CLV AOLV
Set n8-48 [Pull-in/Light Load Id Current] to the level of the load current (q-
axis current) to be applied.
