13.6 INDEX TABLE INDEXING FUNCTION
By specifying indexing positions (angles) for the indexing axis (one
arbitrary axis), the index table of the machining center can be indexed.
Before and after indexing, the index table is automatically unclamped
or clamped.
Explanation
- Indexing axis name
The name of an indexing axis is A, B, C, X, Y, Z, U, V, or W. For
information about which is used, refer to the manual provided by the
machine tool builder.
- Indexing axis setting
Set a rotation axis as an index table indexing axis. That is, set the
following:
Bit 0 (ROT) of parameter No. 1006 = 1
Bit 1 (ROS) of parameter No. 1006 = 1
Bit 2 (ROP) of parameter No. 1006 = 1
Disable the servo-off signal for an index table indexing axis. That is,
set the following:
Bit 1 (SVF) of parameter No. 1802 = 0
Usually, the servo-off state is set for an index table indexing axis.
- Absolute/incremental programming
One of the following indexing positions is used, depending on bit 3
(G90) of parameter No. 7602:
0: Value according to an absolute/incremental G code (G90/G91)
1: Absolute value at all times
An indexing position assumes a positive value for the counterclockwise
direction, and a negative value for the clockwise direction.
-45°
+60°
Command value from A to B (when parameter
G90 (bit 3 of parameter No. 7602) = 0)
G90 B-45.0; or
G91 B-105.0;
A
B

For information about whether an absolute or incremental value is used,
refer to the manual provided by the machine tool builder.
