21.2.3
Traversing indexing axes in AUTOMATIC modes
Traversal to selected positions
An axis defined as an indexing axis can be made to approach any selected position from the
NC part program in AUTOMATIC mode. This includes positions between the defined
indexing positions. These positions are programmed, in the usual way, in the unit of
measurement (mm/inches or degrees) for the axis. The general programming instructions
used for this purpose (
G90
,
G91
,
AC
,
IC
, etc.) are described in the Programming Guide.
Traversal to "Coded positions"
Special instructions can also be used in the part program to traverse indexing axes in the
following way:
Instruction
Effect
CAC
Approach absolute coded position
CACP
Approach absolute coded position in positive direction
CACN
Approach absolute coded position in negative direction
CIC
Approach incremental coded position
CDC
Approach coded position along direct (shortest) path
With absolute positioning, the indexing position to be approached is programmed, and with
incremental positioning, the number of indexes to be traversed in the "+" or "-" direction is
programmed.
On rotary axes, the indexing position can be approached directly across the shortest path
(
CDC
) or with a defined direction of rotation (
CACP
,
CACN
).
V390x 1002.6
If the "Exact stop fine" window is reached and the indexing axis is positioned on an indexing
position, IS "Indexing axis in position" (V390x 1002.6) is set, irrespective of how the indexing
position was reached.
21.2.4
Traversing of indexing axes by PLC
Indexing axes can also be traversed from the PLC user program.
There are various methods:
Concurrent positioning axes: The indexing position to be approached can be specified by the
PLC. See Chapter "Positioning Axes (P2)"
