Changes effective after POWER ON
Data type: BOOLEAN
Meaning:
22930

Changes effective after POWER ON
Data type: DWORD

AXES_SCALE_ENABLE
Activation for axial scaling factor (G51)
min. input limit: 0
Axial scaling is disconnected with this MD.
Meaning:
0: Axial scaling is not possible
1: Axial scaling is possible, i.e. MD DEFAULT_SCALE_FACTOR_AXIS is effective
EXTERN_FIXED_FEEDRATE_F1_ON
Activation of fixed feedrate F1 - F9
min. input limit:
This MD is used to disconnect the fixed feedrates from the setting data
$SC_EXTERN_FIXED_FEEDRATE_F1_F9 [ ].
0: no fixed feedrates with F1 - F9
1: The feedrates from the setting data $SC_EXTERN_FIXED_FEEDRATE_F1_F9 become
effective with the programming of F1 - F9
EXTERN_PARALLEL_GEOAX
Assignment of parallel channel geometry axis
min. input limit: 0
Assignment tables of the axes that are parallel to the geometry axes. This table can be used
to assign parallel channel axes to the geometry axes. The parallel axes can then be
activated with the G functions of the plane selection (G17 - G19) and the axis name of the
parallel axis as geometry axis. An axis interchange can then be executed with the axis
defined via $MC_AXCONF_GEOAX_ASSIGN_TAB[ ].
Precondition: The used channel axes must be active (assigned list place in in
AXCONF_MACHAX_USED).
Entry of a zero deactivated the corresponding parallel geometry axis.
CHBFRAME_POWERON_MASK
Reset channel-specific basic frame after Power On
