● 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

Variants of torque limitation
The following variants are available:
1. No settings entered:
The application does not require any additional restrictions to the torque limits.
2. Fixed limits are required for the torque:
The fixed upper and lower limits or alternatively the fixed motor and regenerative limits
can be specified separately by different sources.
3. Dynamic limits are required for the torque:
– The dynamic upper and lower limit or, alternatively, the dynamic motor and
regenerative limit can be specified separately by different sources.
– Parameters are used to select the source of the current limit.
