2)
Meaning of the bits of $NT_CNTRL[n]
You can make the following settings for the machine adaptation:
Bit 0 = 1
Bit 1 = 1
Bit 2 = 0
Bit 3 = 0
Bit 4 = 0
Bit 5 = 0
Bit 6 = 0
It is not permissible that either the 2nd or the 3rd rotary axis has a Hirth joint.

21.8.3 Behavior at reset and power on
Behavior at reset
Make the following settings so that the kinematics transformation is retained after reset and
the turning tool can be used in JOG mode:
MD20110 $MC_RESET_MODE_MASK
Bit 7 = 1
Bit 16 = 1
MD20112 $MC_START_MODE_MASK
Bit 7 = 0
MD20152 $MC_GCODE_RESET_MODE[ ]
[5] = 1

Meaning
Enable data set
4 = Kinematics active (fixed value)
Fixed sequence of axes
For easier handling of the data, the sequence of the axes is fixed:
1. Rotary table
2. Swivel axis
3. Tool spindle
Rotary table is spindle
Swivel axis is not a spindle
Tool spindle is not a spindle (during turning)
1st rotary axis has no Hirth joint (rotary table)
2nd rotary axis has no Hirth joint (swivel axis)
3rd rotary axis has no Hirth joint (tool spindle)
The current setting for active transformation is retained after reset / part program end.
The current setting of the master spindle is retained.
Start behavior, "active kinematics transformation"
The current setting of the 6th G group is also retained after reset / part program end
(G17, ...).
