Cartesian PTP travel

3.9.11.1

Activating/deactivating Cartesian PTP travel (PTP, PTPG0, PTPWOC, CP)

The Cartesian point-to-point or PTP travel is activated/deactivated in the NC program using G
group 49 commands.
The commands are modal. The default setting is travel with Cartesian path motion (CP).
Contrary to CP, for active PTP travel, only the Cartesian target point is transformed, and the
machine axes are traversed in synchronism.
In order that the Cartesian target point can be uniquely converted into machine axis values, in
addition to position and angular data, information is also necessary that identifies the axis
positions. This data is retrieved from the adjustable addresses STAT (Page 708) andTU
(Page 712).
Precondition
Transformation TRAORI, TRANSMIT, RCTRA or ROBX is active.

Comment
; The previously active transformation is automatically de-
selected.
; The angle for the inclined axis is 45°.
; Activate second concatenated transformation.
; The angle for the inclined axis is 40°.
; Deactivate second concatenated transformation.
Activating point-to-point motion PTP
The programmed Cartesian position in G0 and G1 blocks is approached with synchro‐
nous axis motion.
Activating point-to-point motion PTPG0
Only in G0 blocks is the programmed Cartesian position approached with synchronous
axis motion. In G1 blocks, a switchover is made to CP path motion.
