M1: Kinematic transformation

7.7 Cartesian manual travel (optional)

Path feedrate
An F value input with G1 refers to the fictitious path calculated from the machine axis
coordinates.
Mode change
Cartesian PTP travel only makes sense in the modes AUTOMATIC and MDI.
When changing the mode to JOG, the current setting is retained:
● If PTP travel is set, the axes will traverse in MCS.
● If CP is set, the axes will traverse in WCS.
After returning to the AUTOMATIC or MDI mode, the status that was active before the switch
to JOG mode is restored.
Block search
If the face end transformation (TRANSMIT) is active, different machine axis positions for the
same Cartesian position can result if a program section is executed with block search.
REPOS
The setting for Cartesian PTP travel is not altered during repositioning. If PTP was set in the
interruption block, then repositioning also takes place with PTP.

Note
The "Handling transformation package" option is necessary for the "Cartesian manual travel"
function.
Function
The "Cartesian manual travel" function, as a reference system for JOG mode, allows axes to
be set independently of each other in the following Cartesian coordinate systems:
● Basic coordinate system (BCS)
● Workpiece coordinate system (WCS)
● Tool coordinate system (TCS)
Adjustment and activation is done using machine data:
