Activation of system frames via system variable $P_CHSFRMASK
The system frames of the data management can be activated using system variable
$P_CHSFRMASK. The value of the variables is specified as bit coded according to the
machine data:
MD28082 $MC_MM_SYSTEM_FRAME_MASK (system frames of the data management)
The corresponding system frame of the data management in the channel is activated by setting
a bit of system variable $P_CHSFRMASK to 1. For a value of 0, the currently active system
frame in the channel remains active.
Activating system frames after RESET
After RESET, the system frames in the channel are activated whose bits are set in the following
machine data:
MD24006 $MC_CHSFRAME_RESET_MASK (active system frames after Reset)
Activating system frames for TCARR, PAROT and TOROT, TOFRAME
The system frames for TCARR, PAROT and TOROT, TOFRAME are activated according to the
setting in the following machine data:
MD20150 $MC_GCODE_RESET_VALUES (initial setting of the G groups)
When changing over geometry axes using transformation selection/deselection or the GEOAX
command, the actual total frame $P_ACTFRAME is either deleted or is re-calculated using the
new geometry axis constellation and activated. The system frames and all other frames are
conditioned again in relation to the geometry axes.

NCU-global and channel-specific frames

● Settable frames and grinding frames can only be configured as NCU-global or channel-
specific frames.
● Basic frames can be configured as NCU-global and channel-specific frames.
● An NCU-global frame has the same effect in all channels of the NCU.

● Data management frames are only activated by programming the system variables
$P_CHBFRMASK, $P_NCBFRMASK and $P_CHSFRMASK.
● G500...G599 activates the appropriate settable frame.
0 Data management frames are implicitly described by functions, such as TOROT, PAROT,
external work offset and transformations.
1 Data management frames are not implicitly described by functions, such as TOROT,
