2.9 Program control
Basic logic functions: Mode group, channel, program operation, reset response (K1)

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