■ n8-74: Light Load Iq Level
No.
(Hex.)

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].

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].
■ n8-76: Id Switching Filter Time

Heavy Load Iq Level
Set n8-49 [Heavy 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%.
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
Id Current] to n8-49 [Heavy Load Id Current].
■ n8-78: Medium Load Id Current

Expert
Medium Load Id Current
Sets the level of the pull-in current as a percentage, where E5-03 [PM Motor Rated Current (FLA)] =
100%.

■ n8-79: Pull-in Current @ Deceleration
No.
(Hex.)
Name Description
Default
(Range)
n8-79
(05FE)
Pull-in Current @
Deceleration
Sets the pull-in current that can flow during deceleration as a percentage of the E5-03 [PM Motor
Rated Current (FLA)].
50%
(0 - 200%)
If overcurrent occurs during deceleration, slowly decrease the setting in 5% increments.
Note:
When n8-79 = 0, the drive will use the value set in n8-51 [Pull-in Current @ Acceleration].
