DBX76.6 Indexing axis in position
Application Tool magazine: Activation of a gripper for removing a tool from a magazine is triggered when the
example(s) indexing axis is in position:
DB31, ... DBX76.6 (indexing axis in position) = 1.
This must ensured by the PLC user program.
Special cases, errors, Notes:
... The axis positions entered in the indexing position table for the individual divisions can be changed
through zero offsets (including DRF).
The interface signal:
DB31, ... DBX76.6 (indexing axis in position)
is then set to 1 when the actual position of the indexing axis matches the value entered in the index
table plus the offset.
If a DRF is applied to an indexing axis in AUTOMATIC mode, then interface signal "Indexing axis in
position" remains active even though the axis is no longer at an indexing position.
