Configuring the SINUMERIK control system for the execution of external measurement programs

An automatically generated NC parts program cannot be executed on the SINUMERIK control system if the size of the program exceeds the size of the reserved program memory. In particular, NC part programs created for measuring groups with inputs for secure positions often exceed the maximum size.

Procedure

The following settings should be made to avoid this error:

  1. Change the value of machine data MD18360 $MN_MM_EXT_PROG_BUFFER_SIZE, to increase the size of the FIPO buffer.

    The value must be greater than the size of the measurement program.

  2. Increase the value of machine data MD18362 $MN_MM_EXT_PROG_NUM to run multi-channel measuring programs.

  3. Use the software option "Execution from external storage (EES)".

  4. Shift the measurement program into the NC memory.

Finding machine data MD18360

  1. In SINUMERIK Operate, press key <MENU SELECT> or <F10>.

  2. Select the "Setup" operating area.

  3. Press softkey "Mach. data".

  4. Press softkey "General MD".

  5. Check MD18360 $MN_MM_EXT_PROG_BUFFER_SIZE in the list of machine data.
