Speed controller optimization for drives with oscillating mechanical system

On drives with oscillating mechanical components, it can be useful to optimize the speed controller using optimization run P051=29. The
frequency response of the controlled system for frequencies from 1 Hz to 100 Hz is recorded during optimization.
The drive is first accelerated up to a base speed (P565, FS=20%). A sinusoidal speed setpoint with low amplitude (P566, FS=1%) is then
injected. The frequency of this supplementary setpoint is incremented in 1 Hz steps from 1 Hz up to 100 Hz. An average per frequency is
calculated over a parameterizable number of current peaks (P567, FS=300).
P565 Base speed for frequency response recording
P566 Amplitude for frequency response recording
P567 Number of current peaks for frequency response recording
While the frequency response is being recorded, an average over the
number of current peaks set here is calculated for each measuring
frequency. High values improve the result, but extend the measuring time.
When P567 = 1000, the frequency response recording takes about 9
minutes.
