Self-diagnostic
At this time, the self-diagnostic

not turn ON.
Motion SFC error
It depends on the error whether
detection flag
M2039 is turned ON or not.

• All errors can be cancelled.
• After cancelling errors,
SM50 turns OFF automatically.
All errors are assigned to the
self-diagnostic error codes.
When an error occurs, an error code
is set in SD0, and then SM0 and SM1
turns ON.

Points for migration
The setting of "Output enable/disable
bit" and "Forced output bit" in
Q17nCPUN(-T) are respectively
diverted as "Forced OFF bit" and
"Forced ON bit" in RnMTCPU.
The program can be diverted as it is.
If MULTW /MULTR instructions are
used for writing/reading of data to/from
the shared memory, review the
program. (Refer to section 2.2(6).)
For details of RnMTCPU errors, refer to
section 2.2(5).
Use a compatible I/F to communicate
with peripheral devices.
If PC link communication is used,
replace it with USB communication.
In that case, replace the existing cable
with the A-miniB USB cable as well.

►If M2000, M3072, or D704 is directly
operated in the program to switch the
RUN/STOP status, revise the
program. (Refer to section 2.2(7).)
