7 Drive Machine Data (SIMODRIVE Drive MD) 09.95
7.3.2 Drive MD (data description)
Note:
Before the filter type is configured, the appropriate filter machine data must be input.
Time constant speed setpoint filter 1
1502
Default value Lower input limit Upper input limit Units
0.0 0.0 500.0 ms
Active
at once
Input of time constant for speed setpoint filter 1 (PT1 low-pass). The filter is deactivated when
the data is set to zero.
Time constant speed setpoint filter 2
1503
Default value Lower input limit Upper input limit Units
0.0 0.0 500.0 ms
Active
at once
Input of time constant for speed setpoint filter 2 (PT1 low-pass). The filter is deactivated when
the data is set to zero.
Natural frequency speed setpoint filter 1
1506
Default value Lower input limit Upper input limit Units
2 000.0 10.0 8 000.0 Hz
Active
at once
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.
