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 for measurements in radius/diameter according
to G code group 29 can be manipulated using the following options:
● G code DIAMCYCOF (expansion of channel-specific diameter programming)
This G code deactivates the channel-specific diameter programming during the cycle
execution. In this way, computations in the cycle can always be done in the radius. The
position display and the basic block display are continued according to the state of the
diameter programming before DIAMCYCOF.
In the basic block display, the last displayed value is retained.
● G code DIACYCOFA[AX] (axis-specific diameter programming)
This G code deactivates the axis-specific diameter programming during the cycle execution.
In this way, computations in the cycle can always be done in the radius. In the position
display and in the basic block display, this continues according to the state of the diameter
programming before DIACYCOFA[AX].
In the basic block display, the last displayed value is retained.
● MD27100 $MC_ABSBLOCK_FUNCTION_MASK
Bit0 = 1
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
COMPCAD
...
To avoid bottlenecks in the NCK performance, the basic block display is deactivated
automatically. As a sign that the display blocks are missing, a display block with the string "..."
is generated.
All display blocks are always generated in the single block.

Transverse axis setpoints are always shown as diameter values in the basic
block display.
