Forward mapping of drive position (P-AXIS-00436)

P-AXIS-00436

Forward mapping of drive position

Description

Corresponding to the coupling instructions at drive level, an active gear coupling leads to an offset of the axis positions compared to the programmed command positions in NC channel.

The gear coupling can be activated either by configuration in the axis parameters (see multi_link[i]) or via the HLI interface of the axis (see [FCT-A9]).

In the event of a program restart or an explicitly programmed request of axis positions (#CHANNEL INIT [CMDPOS]), the axis positions and the channel program coordinates are re-initialised. The parameter must be set to 1 if the input coordinates of the gear coupling (e.g. absolute program coordinates) are to be recalculated by forward mapping. See also P-AXIS-00460.
