M Code Output Function - Mitsubishi Electric MELSEC iQ-F Series FX5 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 ([Md.31] Status: b12) 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 ([Md.31] Status: b12) turns on at the positioning start, and an M code is stored in [Md.25] Valid M code.
[Cd.184] Positioning start signal
[Md.141] BUSY signal
M code ON signal
([Md.31] Status: b12)
[Cd.7] M code ON signal OFF request
[Md.25] Valid M code
Positioning
[Da.1] Operation pattern
*1 m1 and m2 represent the configured M codes.
■AFTER mode
M code ON signal ([Md.31] Status: b12) turns on at the completion of positioning, and an M code is stored in [Md.25] Valid M
code.
[Cd.184] Positioning
start signal
[Md.141] BUSY signal
M code ON signal
([Md.31] Status: b12)
[Cd.7] M code ON signal
OFF request
[Md.25] Valid M code
Positioning
[Da.1] Operation pattern
*1 m1 and m2 represent the configured M codes.
