<1> Default setting is dependent on parameter o2-04, Drive Model Selection.
<2> Values shown are specific to 200 V class drives. Double the value for 400 V class drives.

OL /PM OL /PM
Increase this setting if hunting occurs. Decrease to lower the
response.
OL /PM OL /PM
Sets the time constant to make the pull-in current reference and
PM Pull-in I Tc
actual current value agree. Decrease the value if the motor
begins to oscillate, and increase the value if it takes too long for
the current reference to equal the output current.
OL /PM OL /PM
Defines the d-Axis current reference during no-load operation
PM No-load Curr
at a constant speed. Set as a percentage of the motor rated
current. Increase this setting if hunting occurs while running at
constant speed.
OL /PM OL /PM
EnergySav ID Lvl
Sets the d-Axis current reference when running a high load at
constant speed. Set as a percentage of the motor rated current.
OL /PM OL /PM
Sets the d-Axis current reference during acceleration/
PM Pull-in I@Acc
deceleration as a percentage of the motor rated current. Set to a
high value when more starting torque is needed.
OL /PM OL /PM
Adjusts the value when hunting occurs at low speed. If hunting
PM V Error CompT
occurs with sudden load changes, increase n8-54 in increments
of 0.1. Reduce this setting if oscillation occurs at start.
OL /PM OL /PM
PMLoad wk2 Ratio
Sets the ratio between motor and machine inertia.
0: Less than 1:10
0: Lower than 1:10
1: 1:10 to 1:30
1: Between 1:10 to 1:30
2: 1:30 to 1:50
2: Between 1:30 to 1:50
3: More than 1:50
3: Higher than 1:50
OL /PM OL /PM
Prevents output voltage saturation. Should be set just below the
PM Vout Limit
voltage provided by the input power supply.
OL /PM OL /PM
SFdbk G @OV Supp
Sets the gain used for internal speed feedback detection during
ov suppression.
