09.95 7 Drive Machine Data (SIMODRIVE Drive MD)
7.3.2 Drive MD (data description)
Damping speed setpoint filter 1 1507
Default value Lower input limit Upper input limit Units
0.7 0.2 5.0 –
Active
at once
Input of damping for current setpoint filter 1 (PT2 low-pass). The filter is activated via machine
data MD 1200 (No. current setpoint filters) and MD 1201 (Type current setpoint filter).
Note:
• With interpolating axes, the speed setpoint filter must always be parameterized
immediately.
Natural frequency speed setpoint filter 2 1508
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 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 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.
Damping speed setpoint filter 2 1509
Default value Lower input limit Upper input limit Units
0.7 0.2 5.0 –
Active
at once
Input of damping for speed setpoint filter 2 (PT2 low-pass). The filter is activated via machine
data MD 1500 (No. speed setpoint filters) and MD 1501 (Type speed setpoint filter).
