2.2.2 Machine Data for Actual Value Setting, Scratching, and PRESET

Introduction
The behavior of the Scratching, Set actual value, and 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, two variants are available for the functions.
The variants are differentiated by a channel-specific machine data (MD):
MD 28082: $MC_SYSTEM_FRAME_MASK
Bit: 0
1
2
3
4
5
6
Variant 1 without system frame:
The MD does not exist or Bit 0 for the system frame for scratching or actual
value setting is not set.
Variant 2 with system frame:
Bit 0 for the system frame for scratching and actual value setting is set in the
MD.
Display machine data MD 9422: $MM_MA_PRESET_MODE defines the
PRESET/basic offset function in JOG mode.
0:
1:
2:
3:
Note
To hide the PRESET, Set actual value, and Scratching softkeys, MD 9220:
$MM_USER_CLASS_PRESET can also be set.

Actual value setting
Actual value setting with system frame:
- G500 active: The values are written to the system frame.
- G500 not active: An error message is output.
Actual value setting without system frame:
- G500 active (adjustable frames reset): Values are written to the first basic
frame according to the entry in display MD 9245:
$MM_MA_PRESET_FRAMEIDX = Index of basic frame
- G500 not active: An error message is output.
