n8: Permanent Magnet (PM) Motor Control
Use n8 parameters to control the PM motor control.
n8-45
<30>
Speed Feedback
Detection Control
Gain
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.

<30>
Pull-In Current
Compensation Time
Constant
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.
0.0 to
100.0 s
5.0 s −−A 53A —

<30>
Pull-In 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.

Load Current
Sets the amount of d-axis current when using
Energy Saving control.

Heavy Load Current
Level (for PM)
Sets the load level to begin high-efficiency
control of an PM motor.

n8-51
<30>
Acceleration Time
Pull-In Current
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.
0 to
200%
50% −−A 53E —
n8-55
<30>
Load Inertia
This value should be set to correspond to load
inertia.
0: The inertia ratio between the motor and the
load just less than 1:10.
1: The inertia ratio between the motor and the
load is 1:10 to 1:30.
2: The inertia ratio between the motor and the
load is 1:30 to 1:50.
3: The inertia ratio between the motor and the
load is greater than 1:50.
