Software limit switches (SLS) limit the maximum travel distance of an axis.


The positions of the SLS can be configured for the following axis types:

SLS monitoring is only active if the axis


The positions of the SLS must be configured for each axis with P-AXIS-00177 and P-AXIS-00178.


In the NC program, the positions of the SLS can be further limited by NC commands G98 and/or G99. These changes are active up to program end (M30).

Links to other documents

For the sake of clarity, links to other documents and parameters are abbreviated, e.g. [PROG] for the Programming Manual or P-AXIS-00001 for an axis parameter.

For technical reasons, these links only function in the Online Help (HMTL5, CHM) but not in pdf files since pdfs do not support cross-linking.
