The number of blocks before the current block is configured in
MD28402 $MC_MM_ABSBLOCK_BUFFER_CONF[0] and the number of blocks after the
current block is configured in MD28402 $MC_MM_ABSBLOCK_BUFFER_CONF[1].
Boundary conditions
If the length of a display block configured in MD28400 $MC_MM_ABSBLOCK is exceeded,
this display block is truncated accordingly. This is represented by string "..." at the end of the
block.
For preprocessed cycles (MD10700 $MN_PREPROCESSING_LEVEL > 1), the display block
contains only axis positions.
Additional supplementary conditions for the basic block display:
• Modal synchronized action blocks with absolute values are
not taken into account.
• The basic block display is deactivated during block search with or without computation.
• Polar coordinate programming is not shown in Cartesian system.
Radius / diameter values
Diameter values shown in the basic block display and position display may be needed as a
radius for internal calculation. These values can be controlled by the following methods:
• G code DIAMCYCOF (expansion of G code group 26)
Like DIAMOF, this G code deactivates the diameter programming function. The
previously active G code setting remains valid for the position and basic block displays
and enables the cycle to calculate with radius, while a diameter value remains displayed
in the basic block display.
• MD27100 $MC_ABSBLOCK_FUNCTION_MASK
Bit0 = 1 Transverse axis setpoints are always shown as diameter values in the basic
block display.
Behavior while the compressor is active
With active compressor and G/Code group 30 not equal to COMPOF, two display blocks are
generated. The
• First contains the G/Code of the active compressor.
• The second contains the string "..." as character for missing display blocks.
Example:
G0 X10 Y10 Z10 ; Block to be preprocessed for the basic block display
COMPCAD ; Compressor for optimized surface quality (CAD prog.) A
... ; string as character for missing display blocks
