MELSEC-Q
5 DATA USED FOR POSITIONING CONTROL
An M code (
Da.10
) is a number between 0 and 65535 that can be assigned to each
positioning data.
The sequence 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 [X4, X5,
X6, X7] turns ON so that a command for the sub work (e.g. clamping, drilling, tool
change) associated with the M code can be issued.
