Oscillation Damping - Lenze 8400 StateLine C Reference Manual

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
 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
