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 5 programming modes:

• Backlash compensation
• Temperature compensation
• Leadscrew error compensation
• Cross compensation
• Plane compensation

Properties

In general, each axis compensation can be activated for all:

• axis types
• drive types

The conditions required for their effectiveness are described in the related sections on compensation types.

Parametrisation

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…].

The friction compensation functionality is described in FCT-C25.
