[Pr.18] M code ON signal output timing
This parameter sets the M code ON signal output timing.
Choose either WITH mode or AFTER mode as the M code ON signal output timing.
■4-axis module operation example
An M code is output and the M code ON signal is
WITH mode:
turned ON when positioning operation starts.
Positioning start signal
[Y10, Y11, Y12, Y13]
BUSY signal
[X10, X11, X12, X13]
M code ON signal
([Md.31] Status: b12)
[Cd.7] M code OFF request
[Md.25] Valid M code
Positioning
[Da.1] Operation pattern
*1 m1 and m2 indicate set M codes.
*2 If AFTER mode is used with speed control, an M code will not be output and the M code ON signal will not be turned ON.
An M code is a number between 0 and 65535 that can be assigned to each positioning data ([Da.10] M code/Condition data
No./Number of LOOP to LEND repetitions).
The program can be coded to read an M code from the buffer memory address specified by "[Md.25] Valid M code" whenever
the M code ON signal turns ON so that a command for the sub work (e.g. clamping, drilling, or tool change) associated with
the M code can be issued.
• The M code ON signal output timing can be set to each positioning data using the positioning option of the positioning data
([Da.27]).
■Buffer memory address
Refer to the following for the buffer memory address in this area.
