Positioning program example
Data reading timing
The data can be read without regard to the mode (AUTO or MANU) or the status (BUSY or
READY) of the positioning unit.
However, it is recommended to drive the auxiliary equipment when the m code ON signal is
turned ON as shown in the sequence program example above because the m code No. is only
read when an m code drive instruction is executed in the positioning program.

When an m code is executed in the positioning unit,
D9003 (m code No., 0 to 99) and M9051 (m code
ON signal) are set and transmitted to D0 and M203
in the programmable controller.
The programmable controller decodes them, and
turns ON the specified auxiliary drive output.
In this example, when the m code m** (** = 00 to 99)
is executed, the auxiliary relay M** is turned ON in
the programmable controller.
The programmable controller confirms the operation
of the auxiliary equipment, then drives M303 (m
code OFF command).
When receiving the m code OFF command (M303 in
the programmable controller
→
M9003 in the
positioning unit), the positioning unit turns OFF
M9051 (m code ON signal) and proceeds to the next
instruction.
In the programmable controller, M203 is turned OFF.

• This is an m code drive command in WITH mode. The m code
01 is saved in BFM. In the example above, Y11 is driven.
• This is an m code drive command in AFTER mode. The m code
03 is saved in BFM. In the example above, Y13 is driven.
• When the WAIT instruction is executed, m code 00 is saved in
BFM. In the example above, Y10 is driven.
