Example of ambiguity in rotary axis position

The rotary axis position shown in the following diagram can be approached in the negative or
positive direction. The direction is programmed under address A1.

PTP/CP switchover in JOG mode

In JOG mode, the transformation can be switched on and off via a channel-specific NC/PLC
interface signal. This control signal is only effective in JOG mode when the transformation is
active.
After returning to AUTO mode, the state which was last active before switchover is restored.

● Request to switch the traversing type:
● Feedback from the active traversing type:
Operating mode change
The "Cartesian PTP travel" function is only useful in the AUTO and MDI modes of operation.
The
mode is then switched back to AUTO or MDI, the mode that was last active in either mode is
made active again.
REPOS
The setting for "Cartesian PTP travel" is not altered during re-positioning. If
the interruption block, then repositioning also takes place with
"TRAANG", only CP travel is active in
