Oscillation damping
Mechanical oscillations are undesirable effects in every process and they may have an
adverse effect on the single system components and/or the production output.
Mechanical oscillations in the form of speed oscillations are suppressed by the oscillation
damping function.
Mechanical oscillations may occur:
In the voltage range (output voltage is lower than max. voltage)
– Here, the oscillations occur in no-load operation.
– Here, speeds of 40 ... 80 % of the rated speed are typical.
– See subchapter "
Oscillation damping voltage range
".

In the field weakening range (output voltage has reached maximum voltage)
– Here, the oscillations occur in no-load operation and with load.
– Here, speeds higher than the rated speed are typical, especially when the output
frequency is close to the mains frequency.
– See subchapter "
Oscillation damping in the field weakening range
".
