SD41100 Meaning
= 0 (not active) The response of the axis / spindle depends on the setting data:
SD43300 $SA_ASSIGN_FEED_PER_REV_SOURCE(revolutional feed feed rate
for position axes / spindles)
The response of a geometry axis on which a frame acts is to rotate, depending
on the setting data:
SD42600 $SC_JOG_FEED_PER_REV_SOURCE
15.2.2 Traversing of indexing axes in the AUTOMATIC mode
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 Manuals.
Traversal to "Coded positions"
Special instructions can also be used in the part program to traverse indexing axes to the
"coded positions":
Statement 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).
Reaching the indexing position
If the "Exact stop fine" window is reached and the indexing axis is positioned on an indexing
position, the following NC/PLC interface signal is enabled regardless of how the indexing
position was reached.
