12.33.5 Speed setpoint filter

12.33.5
Speed setpoint filters are used to dampen mechanical resonant frequencies in the position
control loop. Bandstops and low passes (PT2/PT1) can both be used as speed setpoint filters.
The tasks of the filter are as follows:
• Adapt the position controller to machinery to be controlled (e.g. table resonance)
• Symmetrize different axis dynamic responses in the case of interpolating axes.
Note
The frequency response analysis of the speed controller includes the filters.
The structure of the position control loop must be taken into account when the speed setpoint
filter is dimensioned.
• Position control to direct measuring system, i.e. load resonance directly in control loop.
• Position control to motor measuring system, i.e. load resonance only indirectly via motor to
control loop.
