H1: Manual traversing
17.10 Position travel in JOG
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 =
Initial situation
Axis 4 [AX4] is referred and is at Position 0 degree.
Approaching the position
The control is switched to JOG mode and machine axis 4 is selected.
The function "Position travel in JOG" is activated:
DB34 DBX13.3 = 1
The NC confirms the activation as soon as the function is effective:
DB34 DBX75.6 = 1
Approaching the position is started via continuous traversing and the JOG traverse key Plus of
the machine control panel.
The axis traverses until it comes to an automatic standstill at the position 100 degrees.
When the position is reached with "Exact stop fine", the following NC/PLC interface signal is set:
DB34 DB75.7 = 1
