In some systems it may be
necessary to avoid certain
frequencies because of
mechanical resonance problems.
With these parameters it is
possible to set limits for three "skip
frequency" regions.

frequency area setting.

0 = Frequency control: The I/O terminal and panel references are frequency references and
the frequency converter controls the output frequency (output frequency resolution = 0.01 Hz)
1 = Speed control: The I/O terminal and panel references are speed references and the
frequency converter controls the motor speed (regulation accuracity ± 0,5%).
2 = Torque control: The I/O terminal and panel references are torque references and the frequency
converter controls the motor torque (regulation accuracity ± 3 % ; proper tuning required: motor
nameplate values, U/f -setting).
