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.

equipment operation.
• This is an m code drive command in WITH mode. The m code
m01
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.

The programmable controller confirms the operation
of the auxiliary equipment, then drives M303 (m

·
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.
