Resonance frequency in the system
Resonance points with an overshoot of less than 5 dB and/or with a frequen‐
cy less than 300 Hz cannot be filtered. Such resonance points are compen‐
sated by an optimal setting of the velocity loop.
The resonance point at 899 Hz can be eliminated by a band-stop filter.

Setting filters
The maximum number of independent filters that can be set for each axis is
4. Typical filter types are "band pass" for filtering a frequency range and "low
pass" for filtering all frequencies below a blocking frequency.
Proceed as follows to set a filter:
1. Select "band rejection" or "low pass"
2. Enter the resonance frequency determined in the measurement in the
"Center frequency" box (here: 900 Hz). The value entered in the "Band‐
