The G code PTP/CP currently active in the program does not affect Cartesian manual travel.
The VDI interface signals are interpreted in the channel DB for geometry and orientation axes.
Activation
The reference system for Cartesian manual travel is set as follows:
● The Cartesian manual travel function is activated with the following machine data:
● JOG traverse motion via SD42650 SC_CART_JOG_MODE
The meaning of the bits is explained in the table below.

MD21106 $MC_CART_JOG_SYSTEM > 0
The BCS, WCS or TCS reference systems are enabled by setting the bits in MD21106
$MC_CART_JOG_SYSTEM.
Standard behavior as before: Bits 0 to 2 = 0, bits 8 to 10 = 0.
Reference system for translation via bits 0-2 and the reference system for orientation via
bits 8-10.
If not all of the bits are set to 0, the process uses the new function. The reference
systems for translation and orientation may be set independently.
