FX Series Positioning Controllers Communication with Programmable Controller 7
7-16
m code information
When a positioning instruction is driven, an m code is output.
At this time, the m code ON signal, the m code No. and the m code wait signal are written to
special auxiliary relays and special data registers (assigned to the X axis).
The m code OFF command is also given through a special auxiliary relay.
m code ON signal: M9051 m code No. (binary): D9003
m code wait signal: M9052 m code OFF command: M9003
In the m code information, the AFTER mode (in which an m code is output after positioning is
completed) or the WITH mode (in which an m code is output while positioning is performed)
can be set for m code output.
Set value "0": No m code
Set value "1", "3" to "99": m code output in the AFTER mode
Set value "100" to "199": m code output in the WITH mode
Positioning data list
The table below shows the list of information set for each command code. The items marked
with “
9
” are required to be set. When a value is entered for an item indicated as “Undefined”, it
is ignored.
The command code “72” indicates interrupt jog feed at two-step speed, and uses two entries
because two speeds are required to be set (Refer to the next page.).
*1: When the speed data is set to “0”, the command code (0) is ignored and the next entry is executed.

• When "2" is set, the actual operation does not correspond to the END instruction.
(In the monitor display by a peripheral unit, however, "END" is displayed.)
When using the END instruction, add "2" at the top of the positioning information
as described above.
