Points To Note - Siemens SINUMERIK 802D sl Function Manual

Note
The following interface signal blocks automatic synchronization in all modes except
referencing mode:
V380x 5005.5 (automatic synchronization locking)
If automatic synchronization is to be activated, V380x 5005.5 must be set to "0".
Following this, one of the axes in the gantry grouping must be switched from follow-up mode
to position-controlled mode. This is achieved with the interface signals:
V380x 0001.4 = 1 (follow-up mode)
V380x 0002.1 = 1 (servo enable)

Channelspecific referencing
Gantry axes can also be referenced on a channel-specific basis:
V3200 0001.0 (activate referencing)
The value of the leading axis machine data is used for the axis sequence during channel-
specific referencing:
MD34110 REFP_CYCLE_NR (axis sequence for channel-specific referencing)
After the reference point of the leading axis has been reached, the synchronized axis is
referenced first as described above.
Referencing from part program with G74
The referencing and synchronization process for gantry axes can also be initiated from the
part program by means of command G74. In this case, only the axis name of the leading
axis may be programmed. The operational sequence is analogous to that described for axis-
specific referencing.
Position measuring system with distancecoded reference marks
In order to ensure that large distances do not need to be traversed while approaching the
reference point, it is possible to use a position measuring system with distance-coded
reference markers as the only measuring system for gantry axes. In this way the measuring
system is referenced after traversal of a short path (e.g. 20 mm). The procedure for
referencing the gantry axes is the same as that described for the normal incremental
measuring system.
