M Code Output Function - Mitsubishi Electric RD77MS2 User Manual

M code output function

The "M code output function" is used to command sub work (clamping, drill rotation, tool replacement, etc.) related to the
positioning data being executed.
When the M code ON signal ([Md.31] Status: b12) is turned ON during positioning execution, a No. called the M code is stored
in "[Md.25] Valid M code".
These "[Md.25] Valid M code" are read from the CPU module, and used to command auxiliary work. M codes can be set for
each positioning data. (Set in setting item "[Da.10] M code/Condition data No./Number of LOOP to LEND repetitions/Number
of pitches" of the positioning data.)
The timing for outputting (storing) the M codes can also be set in the "M code output function".
M code ON signal output timing
The timing for outputting (storing) the M codes can be set in the "M code output function". (The M code is stored in "[Md.25]
Valid M code" when the M code ON signal is turned ON.)
The following shows the two types of timing for outputting M codes: the "WITH mode" and the "AFTER mode".
■WITH mode
The M code ON signal is turned ON at the positioning start, and the M code is stored in "[Md.25] Valid M code".
