Adjust this parameter in the following circumstances.
• Increase the setting value if resonance or hunting occurs during use of the overvoltage suppression function.
• Reduce the setting value in increments of 0.05 if motor responsiveness is low during use of the overvoltage
suppression function.

Note:
• If the condition n8-74 ≤ n8-75 [LghtLoadCurLvl 2] is not met, oPE08 [Parameter Selection Error] is displayed.
• Between n8-74 and n8-75 and the level of the pull-in current from n8-48 to n8-78 [MedLoad Id Level], the change is linear.

V/f CL-V/f OLV CLV AOLV
To prevent saturation of the output voltage, set the output voltage limit.
Normally there is no need to configure 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 working, as a magnification value.
Normally there is no need to configure this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain used for speed estimation. Normally there is no need to change
this setting.
V/f CL-V/f OLV CLV AOLV
Selects the speed estimation method. Normally there is no need to change
this setting.
V/f CL-V/f OLV CLV AOLV
Set n8-48 [Pull-In Current (for PM Motors)] to the level of the load current
(q-axis current) to be applied.
V/f CL-V/f OLV CLV AOLV
Set n8-78 [MedLoad Id Level] to the level of the load current (q-axis
current) to be applied.
