<1> Default setting value is dependent on parameter o2-04, Drive Model Selection.
<2> Parameter can be changed during Run.
<3> Setting range varies depending on drive software version. Software versions PRG: 1018 and later disable pull-in current when n8-48 = 0 and
allow this parameter to be changed during run.

Description
Tunes the line-to-line motor resistance continuously during
operation.
0: Disabled
1: Enabled
n8: Permanent Magnet (PM) Motor Control
Use n8 parameters to control the PM motor control.
Sets the gain for internal speed feedback detection control.
This parameter does not typically require adjustment.
Increase this setting if hunting occurs.
Decrease to lower the response.
Sets the time constant to make the pull-in current and actual
current value agree.
Decrease the value if the motor begins to oscillate.
Increase the value if it takes too long for the current reference
to equal the output current.
Defines the amount of current provided to the motor during
no-load operation at a constant speed.
Set as a percentage of the motor rated current. Increase this
setting when hunting occurs while running at a constant
speed.
Sets the amount of d-Axis current when using Energy Saving
control.
Sets the pull-in current during acceleration as a percentage
of the motor rated current (E5-03). Set to a high value when
more starting torque is needed.
Sets the time constant for voltage error compensation. Adjust
the value when hunting occurs at low speed.
Increase in steps of 0.1 or disable the compensation by setting
n8-45 to 0 when hunting occurs with sudden load changes or
when oscillations occur at start.
Sets the ratio between motor and machine inertia.
0: less than 1:10.
1: between 1:10 to 1:30.
2: between 1:30 to 1:50.
3: higher than 1:50.
Sets the limit for the output voltage. Adjustment is normally
needed only if the input voltage is below the n8-62 set value.
In this case set n8-62 to the input voltage.
Sets the gain used for internal speed feedback detection
during ov Suppression
Determines the method of the output voltage limit.
0: Feedback method
1: Feed forward method Use the feed forward method if
oscillation occurs in the constant output range.
Sets the current level to switch the output voltage limit
sequence. Set as a percentage of the motor rated current
(E5-03).
Determines the hysteresis of the current level to switch the
output voltage limit sequence. Set as a percentage of the
motor rated current (E5-03).
Sets the speed level to switch the output voltage limit
sequence. Set as a percentage of the maximum output
frequency (E1-04).
Sets the amount of pull-in current that flows through the
motor while operating at constant speed. Set as a percentage
of the motor rated current (E5-03). Increase this setting if
hunting occurs at constant speed.
