Servo control
3.5 Torque setpoint limitation
Figure 3-8
Note
This function is effective immediately without any settings. The user can also define further
settings for limiting the torque.
Properties
The connector inputs of the function are initialized with fixed torque limits. If required, the
torque limits can also be defined dynamically (during operation).
● A control bit can be used to select the torque limitation mode. The following alternatives
● Additional power limitation configurable
● The following factors are monitored by the current controller and thus always apply in
● Offset of the setting values also possible (see "Example: Torque limits with or without
offset").
● The following torque limits are displayed via parameters:
– Lowest of all upper torque limits with and without offset
– Highest of all lower torque limits with and without offset

Current/torque setpoint limiting
are available:
– Upper and lower torque limit
– Motor and regenerative torque limit
– Motor mode power limit
– Regenerative mode power limit
addition to torque limitation:
– Stall power
– Maximum torque-generating current
