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.

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
