Signal flow

Update
Cyclic
Signal state 1
The signal is set to "1" in the following cases:
• The indexing axis has reached the indexing position with "Exact stop fine".
• The indexing axis is located at the indexing position, which was approached in the AUTO-
MATIC mode with CAC, CACP, CACN, CDC or CIC.
Signal state 0
The signal is "0" in the following cases:
• The axis is not defined as an indexing axis.
• A traversing command is active, and the indexing axis is traversed.
• The indexing axis is located at a position which is not an indexing position.
• In the AUTOMATIC mode, the indexing axis was not positioned using CAC, CACP, CACN,
CDC or CIC but instead is traversed to any position, for example with AC or DC.
• The "Controller enable" of the indexing axis is withdrawn.
Additional information
Signal is irrelevant for axes that have not been defined as indexing axes.
Application example
Tool magazine: Activation of the gripper to remove the tool from the magazine is initiated as
soon as the indexing axis is in position. The PLC user program must ensure this happens.
Special cases or errors
The axis positions entered in the indexing position table for the individual divisions can be
changed using work offsets (including DRF).
The interface signal "Indexing axis in position" is set if the actual position of the indexing axis
assumes the position value entered into the indexing table plus the offset.
If a DRF offset is applied to an indexing axis in AUTOMATIC mode, then the "Indexing axis in
position" interface signal remains active even though the axis is no longer at an indexing
position.

In addition to the limit value MD36931 $MA_SAFE_VELO_LIMIT, depending on the active safe-
