Properties
The connector inputs of the function are initialized with fixed torque limits. If requi-
red, the torque limits can also be defined dynamically (during operation).
S A control bit can be used to select the torque limitation mode. The following
alternatives are available:
– Upper and lower torque limit
– Motor and regenerative torque limit
S Additional power limitation configurable
– Motor mode power limit
– Regenerative mode power limit
S The following factors are monitored by the current controller and thus always
apply in addition to torque limitation:
– Stall power
– Maximum torque-generating current
S Offset of the setting values also possible (see Fig. 3-10)
S 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
