High Frequency
Injection Level
PM Harm Inj Freq
Sets the frequency in Hz for the superimposed signal used for
superimposed harmonics. Enabled when n8-57 = 1.

High Frequency
Injection Amplitude
PM Harm Inj Amp
Sets the amplitude for superimposed harmonics according to the
voltage class of the motor. Adjust this value when there is too
much or too little current as a result of the settings assigned to
motor parameters.
Enabled when n8-57 = 1.
There is normally no need to change this parameter from the
default value.

Speed Feedback
Detection Control Gain
(for PM Motors)
PM Spd Fdbk Gain
Increase this setting if hunting occurs. Decrease to lower the
response.

Pull-In Current
Compensation Time
Constant (for PM
Motors)
PM Pull-in I Tc
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
Max.: 100.0

(053B)
Pull-In Current (for PM
Motors)
PM No-load Curr
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
