7 Drive Machine Data (SIMODRIVE Drive MD) 12.93
7.1.2 MSD MD (data description - SW 3)
Integral-action time speed controller motor 1
32
Default value Lower input limit Upper input limit Units
20 5 6 000 ms
Active
at once
Input of integral-action time (t
N
) for the speed controller. The speed controller has a PI function
which can be set separately for eight gear stages.
Note:
A speed controller adaptation can be implemented only for gear stage 1 (see MD 203).
Smoothing time torque setpoint motor 1
35
Default value Lower input limit Upper input limit Units
3 3 1 000 ms
Active
at once
Input of smoothing time for the torque setpoint. MD 45 and MD 46 are the corresponding
machine data.
Note:
The smoothing function can be activated in machine data MD 44.
Encoder phase error compensation motor 1
36
Default value Lower input limit Upper input limit Units
0 -400 +400 –
Active
at once
Phase errors in the encoder signals can be compensated by means of a correction function.
The amplitude of this function is specified via machine data MD 36.
Note:
Default value 0 means no correction.
Switchover speed motor encoder evaluation motor 1
37
Default value Lower input limit Upper input limit Units
32 000 0 32 000 rev/min
Active
at once
Input of the switchover speed for evaluation of the motor encoder. In this case, it is possible to
switch between the square-wave and SINE/COSINE evaluation modes. Square-wave
evaluation is applied at speeds above the maximum value entered.
