With modulo axes, the programmed value, which may be outside the modulo range, is 
displayed in the basic block display. 
 
 
 
Note 
As a basic rule the positions are represented in the WCS or the SZS. 
The basic block display can be activated or deactivated with setting data 
SD42750 $SC_ABSBLOCK_ENABLE. 
 
Configure basic block display 
The basic block display can be configured via the following machine data: 
 
NCK machine data for basic block display  Meaning: 
MD28400 $MC_MM_ABSBLOCK  Activate basic block display 
MD28402 
$MC_MM_ABSBLOCK_BUFFER_CONF[2] 
Size of display buffer 
Display of machine data  Position values to be set: 
MD9004 $MM_DISPLAY_RESOLUTION  For metric measurements 
MD9011 $MM_DISPLAY_RESOLUTION_INCH  For inch measurements 
MD9010 $MM_SPIND_DISPLAY_RESOLUTION 
 
Settable coordinate system for spindle display 
resolution 
MD9424 $MM_MA_COORDINATE_SYSTEM  For actual value display in WCS or SZS 
These display machine data are copied to NCK machine data 
MD17200 $MN_GMMC_INFO_UNIT[0] to MD17200 $MN_GMMC_INFO_UNIT[3] allowing 
them to be accessed from the NCK. 
Activation 
The basic block display is activated by MD 28400 $MC_MM_ABSBLOCK by means of 
Power On. If MD28400 $MC_MM_ABSBLOCK is set to 1, a channelspecific display buffer 
(FIFO) is created during power-up. 
Size of display buffer (FIFO) = (MD28060 $MC_MM_IPO_BUFFER_SIZE + MD28070 
$MC_MM_NUM_BLOCKS_IN_PREP) multiplied by 128 bytes. This corresponds to a size of 
6KB in the machine data default setting. 
Optimizing the size of the display buffer 
The memory requirement can be optimized by entering a value between 128 and 512. The 
display blocks preprocessed in the display buffer are transferred to the HMI via a 
configurable upload buffer. 
Maximum size of upload buffer is obtained by multiplying 
(MD28402 $MC_MM_ABSBLOCK_BUFFER_CONF[0] + 
MD28402 $MC_MM_ABSBLOCK_BUFFER_CONF[1] + 1) by the block length configured in 
MD28400 $MC_MM_ABSBLOCK.
