DBX76.6 Indexing axis in position
Edge evaluation: No
Signal state 1 or The signal is influenced according to the "Exact stop fine":
edge change 0 → 1 When "Exact stop fine" is achieved, the signal is set.
When exiting "Exact stop fine", the signal is reset.
•
Note:
If the "Exact stop fine" window is reached and the indexing axis is positioned on an indexing
position, the signal is enabled regardless of how the indexing position was reached.

FS (following spindle) active
Signal(s) updated: Cyclic
The machine axis is currently operating as the following spindle.
The following spindle thus follows the movements of the leading spindle in synchronous
operation in accordance with the transmission ratio.
Note:
The signal is relevant only in synchronous operation.
The machine axis is not currently operating as the following spindle.
In the case of faults/disturbances on the following spindle which result in cancellation of the
FS "servo enable", the coupling relationship between the FS and LS is reversed and switched
over to an actual-value coupling internally in the control under certain circumstances.
DB31, ... DBX84.4 (Synchronous mode)
DB31, ... DBX99.0 (LS active)
Signal(s) updated: Cyclic
The indexing axis is located on an indexing position.
The indexing axis has been positioned with instructions for "Coded Position".
