7 Drive Machine Data (SIMODRIVE Drive MD)
7.3.2 Drive MD (data description)
Note:
Before the filter type is configured, the appropriate filter machine data must be input.
1502
Default value
0.0
Input of time constant for speed setpoint filter 1 (PT1 low-pass). The filter is deactivated when
the data is set to zero.
1503
Default value
0.0
Input of time constant for speed setpoint filter 2 (PT1 low-pass). The filter is deactivated when
the data is set to zero.
1506
Natural frequency speed setpoint filter 1
Default value
2 000.0
Input of natural frequency for speed setpoint filter 1 (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
1500 (No. speed setpoint filters) and MD 1501 (Type speed setpoint filter).
Note:
With interpolating axes, the speed setpoint filter must always be parameterized immediately.
