Supplementary Conditions

Axis is indexing axis
The axis is not traversed and an alarm is output if the axis to be traversed is an indexing axis
and the position to be approached does not match an indexing position.
Frames active
All active frames are ignored. Traversing is performed in the machine coordinate system.
Correction values active
Active correction values (DRF, external zero offset, synchronized action offset $AA_OFF,
online tool offset) are also traversed.
An alarm is issued if an offset movement (DRF, external zero offset, synchronized action offset
$AA_OFF, online tool offset) is made during the approach of a variable position in JOG. The
position to be approached in the machine coordinate system is not reached; instead a position
that would have been reached without active offset movement is reached. The NC/PLC
interface signal DB31, ... DBX75.7 is not reported.
Working area limits
Working-area limitations (in BCS and WCS) are considered and the axis motion is stopped on
reaching the limits.

Application example

Objective
A rotary axis (machine axis 4 [AX4]) is to be moved to Position 100 degrees with the "Position
travel in JOG" function.
Parameter assignment
The position to be approached is specified via the user interface as follows:
SD43320 $SA_JOG_POSITION[AX4] = 100; position to be approached for machine axis 4 =
196
100
