Indexing axis in position
Signal state 0 or
edge change 1 → 0
• The axis is not defined as an indexing axis.
• The indexing axis is traversing:
DB31, ... DBX64.7/64.6 (Travel command+/-) is active.
• The indexing axis is located at a position which is not an indexing position.
Examples:
– In JOG mode after abortion of travel movement, e.g. with RESET
– in Automatic mode: indexing axis has, for example, approached a selected position
controlled by an
AC or DC instruction
• The indexing axis has not been positioned with instructions for coded positions (
CAC, CACP,
CACN, CDC, CIC) in automatic mode.
• The "Servo enable" signal for the indexing axis has been canceled:
DB31, ... DBX2.1 (Servo enable)

... Axes that are not defined as indexing axes:

Application
example(s)
Tool magazine: Activation of a gripper for removing a tool from a magazine is triggered when the
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.
