7.6 Vibration suppression (hysteresis)
Low rotation speeds and higher relative vibrations between the rotor and the
stator can cause disturbance signals that reverse the direction of rotation.
Electronic suppression (hysteresis) to eliminate these disturbances is
connected at the factory. Disturbances caused by the radial stator vibration
amplitude and by the torsional vibration of the rotor are suppressed.
