(2) PCPU error cause(D9184) ..............................Data from the PCPU to the SCPU
This register is used to identify the nature of errors occurring in the PCPU part
of the sequence program.
Error Code Error Cause Operation when Error Occurs Action to Take
1 PCPU software fault 1
2 PCPU operation synchronization time over
3 PCPU software fault 2
30 PCPU/SCPU hard ware fault
All axes stop immediately, after
which operation cannot be
started.
Reset with the reset key.

Indicates the slot No.(0 to 7)
where the AC motor drive module
with the fault is loaded.
Indicates the stage No. of the base
on which the AC motor drive module
with the fault is loaded.

The servo error detection flag
(M2408+20n) of the
corresponding axis turns ON,
resulting in a servo-off status.
After that, operation is performed
in accordance with "ADU servo
error-time processing setting" in
system settings.
Perform reset with the key.
If the error occurs after reset,
change the ADU module since it
may be faulty.

Hardware fault of module loaded on motion CPU
base unit or extension base unit.

Indicates the slot No.(0 to 7)
where the module with the fault
is loaded.
Indicates the stage No. of the base
on which the module with the fault
is loaded.

Reset with the reset key.
If the error reoccurs after
resetting, the relevant module or
the relevant slot(base unit) is
probably faulty: replace the
module/base unit.
