Note:
•
Current setpoint filter 1 is preset to the current controller sampling time MD 1000 =
125
µ
s for damping of the encoder torsional natural frequency.

Input of natural frequency for current setpoint filter 2 (PT2 low-pass). An entry of < 10 Hz as
the natural frequency of the low-pass filter initializes the filter as a proportional element with a
gain of 1 independently of the associated damping. The filter is activated via machine data MD
1200 and MD 1201.
