Fig. 10-17 Mechanical system measurement
Amplitude:
Entered in % of maximum current of power section.
Bandwidth:
The bandwidth should only be changed if the previous optimization runs do not
produce satisfactory results (can only be changed in mechanical system part 1).
Averaging:
Should only be reduced if the traversing range of the machine is inadequate.
Offset:
Constant velocity during measurement (changing positive/negative sign for
optimum utilization of traversing range).
