Set the general machine data
MD 18600: MM_FRAME_FINE_TRANS = 0, the fine offset cannot be entered or
programmed.

4.11.3 Preset actual value memory, preset, scratching
Introduction
The behavior of the scratching and preset actual value memory, PRESET
functions is influenced by a number of machine data. The selected settings also
affect operation. (Display of softkeys and values, saving of input values.)

With the introduction of system frames in software version 6, two variants are
available for the functions. The variants are differentiated using a channel-specific
machine data MD 28082: MM_SYSTEM_FRAME_MASK:
Bit: 0 Preset, scratching
1 External work offset
2 TCARR, PAROT
3 TOROT, TOFRAME
4 Workpiece reference points
5 Cycles
6 Frame transformation
Variant 1 without system frame:
The MD does not exist (older NCK software versions) or bit 0 for system frame for
scratching and preset is not set.
Variant 2 with system frame:
Bit 0 for system frame for scratching and preset is not set in the MD.
Display machine data MD 9422: MA_PRESET_MODE defines the PRESET/base
offset in the JOG mode.
0: No softkey
1: The old PRESET in the Machine operating area (default).
2: Preset actual value memory:
NCK without system frame: Setting only possible with active G500 in the
base offset, otherwise error message.
NCK with system frame: Setting in the system frame possible.
The basic frame is not used with G500 in the system frame.
3: Preset actual value memory: NCK with/without system frame: Setting
possible in the currently active frame.
