7 Drive Machine Data (SIMODRIVE Drive MD)
7.1.2 MSD MD (data description - SW 3)
265
Default value
32.0
Input of P gain (K ) for the speed controller. The speed controller has a PI function which can
p
be set separately for eight gear stages.
Note:
A speed controller adaptation can be implemented only for gear stage 1 (see MD 293).
266
Integral-action time speed controller motor 2
Default value
20
Input of integral-action time (t
which can be set separately for eight gear stages.
Note:
A speed controller adaptation can be implemented only for gear stage 1 (see MD 293).
267
Switchover speed motor encoder evaluation motor 2
Default value
32 000
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.
268
Default value
50
Input of hysteresis for machine data MD 267 (switchover speed for motor encoder evaluation).
269
Default value
100
Input of the maximum permissible torque referred to the rated torque of the motor. The setting
of the limit values is referred to the rated motor torque in the constant torque range. At speeds
above the rated value, i.e. in the constant power range, the torque limitation is referred to the
appropriate working point.
