Overview
Task
Axis compensations rectify inaccuracies in tool guidance caused by mechanical errors such as backlash, errors in spindle pitch or temperature fluctuations.
A distinction is made between 7 programming modes:
- Backlash compensation
- Temperature compensation
- Cross compensation
- Plane compensation
- Leadscrew error compensation
- Friction compensation
- Crosstalk compensation
Characteristics
In general, each axis compensation can be:
- activated for all axis types, and
- used with all drive types
The conditions required for their effectiveness are described in the related sections on compensation types.
Parameterisation
Specific parameters must be configured for each axis compensation in order to activate them. They are described for each compensation type in the section “Parameterisation”.
Programming
Axis compensations can be activated and deactivated in the NC program with the command X[COMP…].
Mandatory note on references 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 (HTML5, CHM) but not in pdf files since pdfs do not support cross-linking.
The friction compensation functionality is described in FCT-C25.
