M Code Output Function - Mitsubishi Electric MELSEC iQ-R-RD75P4 User Manual

M code output function

M code output function is used to command a subsidiary work (such as clamping, drilling, and tool replacement) related to the
positioning data being executed.
When M code ON signal [X4, X5, X6, X7] turns on during positioning, a number called an M code is stored in [Md.25] Valid M
code.
The value set in [Md.25] Valid M code is read from the CPU module, and used to command a subsidiary work. An M code can
be set for each positioning data. (Set the M code in [Da.10] M code, one of the setting items of positioning data.)
Output timing of M code ON signal
M code output function can set the output (storage) timing of M codes. (The M code is stored in [Md.25] Valid M code when M
code ON signal is turned on.)
The following two types of timing for outputting M codes are provided: WITH mode and AFTER mode.
■WITH mode
M code ON signal [X4, X5, X6, X7] turns on at the positioning start, and an M code is stored in [Md.25] Valid M code.

code.
