P-gain speed controller motor 2
265
Default value Lower input limit Upper input limit Units
32.0 1.0 120.0 –
Active
at once
Input of P gain (Kp) 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 293).
Integral-action time speed controller motor 2
266
Default value Lower input limit Upper input limit Units
20 5 6 000 ms
Active
at once
Input of integral-action time (tN) 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 293).
Switchover speed motor encoder evaluation motor 2
267
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.
Hysteresis MD 267 motor 2
268
Default value Lower input limit Upper input limit Units
50 0 500 rev/min
Active
at once
Input of hysteresis for machine data MD 267 (switchover speed for motor encoder evaluation).
1st torque limiting value motor 2
269
Default value Lower input limit Upper input limit Units
100 5 180 %
Active
at once
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.
