Initial Rotor Position Estimation
Current
Sets the current used for initial rotor position estimation as a percentage of the motor rated
current (E5-03). If the motor nameplate lists an “Si” value, that value should be entered here.
Default: 50%
Min: 0%
Max: 100%

n8-02
(541H)
Pole Attraction Current
Sets the current during initial polar attraction as a percentage of the motor rated current. Enter a
high value when attempting to increase starting torque.
Default: 80%
Min: 0%
Max: 150%

n8-47
(53AH)
Pull-In Current Compensation
Time Constant
Sets the time constant to make the pull-in current reference and 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.
Default: 5.0 s
Min: 0.0 s
Max: 100.0 s

n8-48
(53BH)
Pull-In Current
Defines the d-axis current reference during no-load operation at a constant speed. Set as a
percentage of the motor rated current. Increase this setting if hunting occurs while running at
constant speed.
Default: 30%
Min: 20%
Max: 200%

n8-49
(53CH)
d-Axis Current for High Efficiency
Control
Sets the d-axis current reference when running a high load at constant speed. Set as a percentage
of the motor rated current.
Default:
<14>
Min: -200.0%
Max: 0.0%
