Detailed Description
2.5 Block search
Auxiliary spindle functions after block search
Control system response and output
Machine data:
MD11450 MN_SEARCH_RUN_MODE
determines the control system response after the end of the block search via the following
bits:
Bit 0 = 0:
Bit 0 = 1:
Bit 1 = 0:
Bit 1 = 1:
Bit 2 = 0:
Bit 2 = 1:
Bit 3 = 0:
Bit 3 = 1:
The programmed spindle values are collected in the block search system variables during
block searches irrespective of the configuration.
Spindle programming in ASUBs
The collective spindle programming can be output in an ASUB after
• Block search
• Output of action blocks:
In this way it can be ensured that the maximum permissible speed of the active tool is not
exceeded, regardless of the block search target.
For further information about the spindle auxiliary functions and a description of the new
block search system variables, refer to:

NC Stop following output of the last action block (default).
NC Stop following output of the last action block only if the PLC requests this with:
DB21... DB32.6 (last action block active).
No automatic ASUB start after block search.
Automatic start of user program
/_N_CMA_DIR/_N_PROG_EVENT_SPF as an ASUB.
Output of spindle auxiliary functions (M3, M4, M5, M19, M70) in action blocks.
Output of the spindle auxiliary functions and spindle setpoints after block search is
suppressed (e.g., output in ASUB).
Cascaded block search is enabled (i.e., several search targets can be specified).
Cascaded block search is disabled.
