Notes regarding effects of machine data
If the function is used workpiece related, the machine data are altered during workpiece
machining and in setup mode. This is possible by:
• altering the MD from the PLC
• altering the MD during configuring (user memory submodule UMS)
• altering the MD via CL 800
If the machine data are altered during configuring, this can be carried out without using the
installation mode. They become active immediately after they have been altered without a
warm restart or RESET being necessary.
If the indexing machine data are altered during machining with the indexing function, they
become active after approximately 100 ms!
