Name Description
Default
(Range)
n8-74
(05C3)
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].
■ n8-75: Medium Load Iq Level (low)
No.
(Hex.)
Name Description
Default
(Range)
n8-75
(05C4)
Medium Load Iq Level (low)
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].

apply, where E5-03 [Motor Rated Current (FLA)] = a setting value of 100%.
90%
(0 - 255%)
Note:
The change is linear between n8-75 [Medium Load Iq Level (low)] and n8-77 and the level of the pull-in current from n8-78 [Medium Load
