In order to protect the mechanism against excessive torques, the torque can be
limited with dr11.
Maximum permissible torque in% of rated torque
If a motor is energized with multiple of the maximum permissible value, it can not
be protected against destruction either by the motor protection function nor by the
temperature sensors. Therefore the maximum current can be limited.
Maximum permissible motor current in% of the rated motor current
The application point of the field weakening operation and the limiting characteristic
of the motor is defined with dr13 and dr25 (=> Chapter 6.2.10 Field weakening).
The default values are generally sufficient for an initial start-up.
