Cartesian Manual Traversing (Option) - Siemens SINUMERIK 840DE sl Function Manual

In addition, the following special features should be noted:
● Blending is always done in the machine coordinate system and it thus high-performance in
terms of time. The criteria for G642 is always interpreted in the machine coordinate system
and not as usual in the Cartesian basic coordinate system.
● Smoothing G641 is determined as a function of the fictitious path calculated from the
machine axis coordinates.
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.
