Speed Fdbk Gain @ oV
Suppression
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.
1.50
(0.00 - 10.00)
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.

Light Load Iq Level
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% .
30%
(0 - 255%)
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] .

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% .
50%
(0 - 255%)
Note:
•
If n8-74 [Light Load Iq Level] > n8-75 , 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] .
