1000
Run mode suspended or failure of main CPU
(1) Malfunctioning due to noise or other reason
(2) Hardware fault
(1) Take noise reduction measures.
(2) Reset the CPU module and RUN it again. If the same
error is displayed again, this suggests a CPU hardware
fault. Contact your local Mitsubishi representative.

1010
1011
1012
Entire program was executed without the execution of an END
instruction.
(1) When the END instruction is executed, it is read as another
instruction code, e.g. due to noise.
(2) The END instruction has been changed to another instruction
code somehow.
(1) Take noise reduction measures.
(2) Reset the CPU module and RUN it again. If the same
error is displayed again, this suggests a CPU hardware
fault. Contact your local Mitsubishi representative.
1101
The sequence program storing built-in RAM/program memory in the
CPU module is faulty.
1102 The work area RAM in the CPU module is faulty.
1103 The device memory in the CPU module is faulty.
1104 The address RAM in the CPU module is faulty.
This suggests a CPU module hardware fault. Contact your
nearest Mitsubishi representative.
1105 The CPU shared memory in the CPU module is faulty.
(1) Take noise reduction measures.
(2) Reset the CPU module and RUN it again. If the same
error is displayed again, this suggests a CPU hardware
fault. Contact your local Mitsubishi representative.

1200
The operation circuit for indexing in the CPU module does not
operate normally.
1201 The hardware (logic) in the CPU module does not operate normally.
1202
The operation circuit for sequence processing in the CPU module
does not operate normally.
This suggests a CPU module hardware fault. Contact your
nearest Mitsubishi representative.
1203
The operation circuit for indexing in the CPU module does not
operate normally.
1204 The hardware (logic) in the CPU module does not operate normally.
1205
The operation circuit for sequence processing in the CPU module
does not operate normally.
1206
The DSP operation circuit in the CPU module does not operate
normally.
This suggests a CPU module hardware fault. Contact your
nearest Mitsubishi representative.
Q4AR
There is an output module with a fuse blown.
(1) Check ERR. LED of the output modules and replace the
module of which LED is lit.
(2) The module with a fuse blown can also be identified
using peripheral device. As the special registers SD1300
to SD1331 is corresponding to the module with a fuse
blown and set to bit of "1", the module can be checked
with monitoring.

There is an output module with a fuse blown.
(1) Check LED of the output modules and replace the fuse
of the module of which LED is lit.
(2) Read the common information of the error using the
peripheral device and replace the fuse at the output
module corresponding to the numerical value (module
No.) reading.
Alternatively, monitor the special registers SD1300 to
SD1331 with the peripheral device and change the fuse
of the output module whose bit has a value of "1".

(2) External power supply for output load is turned off or
disconnected.

(3) Check whether the external power supply for output load
is ON or OFF.

1301
External power supply for output load is turned off or disconnected.
(For future use)
Check whether the external power supply for output load is
ON or OFF.
