CPU
1310 An interruption has occurred although there is no interrupt module.
This suggests a hardware fault for any of the mounted
modules. Therefore, check the mounted modules and
change the faulty module. Contact your nearest Mitsubishi
representative.
• There was no response from the intelligent function module at initial
updated.
• The size of the buffer memory of the intelligent function module is
wrong.
This suggests a CPU module hardware fault. Contact your
nearest Mitsubishi representative.
QCPU
Rem
1401
When parameter I/O allocation was being made, there was no return
signal from the special function module at initial communication.
When error is generated, the head I/O number of the special function
module that corresponds to the common information is stored.
This suggests a hardware fault for the special function
module that was accessed. Contact your nearest Mitsubishi
representative.
QnA
The intelligent function module was accessed in the program, but
there was no response.
This suggests a CPU module hardware fault. Contact your
nearest Mitsubishi representative.
QCPU
Rem
1402
The special function module was accessed at the execution of a
FROM/TO instruction set, but there was no response.
When an error is generated, the program error location
corresponding to the individual information is stored.
This suggests a hardware fault for the special function
module that was accessed. Contact your nearest Mitsubishi
representative.
QnA
1403
• There was no response from the intelligent function module when
the END instruction is executed.
• An error occurrence was detected at the intelligent function module.
This suggests a hardware fault for the special function
module that was accessed. Contact your nearest Mitsubishi
representative.
QCPU
Rem
1411
When performing a parameter I/O allocation, the special function
module could not be accessed during initial communications. When
error is generated, the head I/O number of the special function
module that corresponds to the common information is stored.
Rem
1412
The FROM/TO instruction set could not be executed, due to a
system bus error with the special function module.
When an error is generated, the program error location
corresponding to the individual information is stored.
This suggests an error for the special function module, CPU
module or base module. Contact your nearest Mitsubishi
representative.
The QCPU of function version A is mounted.
(1) Remove the QCPU of function version A from the base
module.
(2) This suggests an error for the intelligent function
module, CPU module or base module. Contact your
nearest Mitsubishi representative.
QCPU
function Ver.
B or later
1413
An error was detected on the Q bus.
• Weight length timeout, arbitration timeout
This suggests an error for the special function module, CPU
module or base module. Contact your nearest Mitsubishi
representative.
QCPU
Rem
Fault of the mounted module was detected.
The QCPU of function version A is mounted.
(1) Remove the QCPU of function version A from the base
module.
(2) This suggests an error for the intelligent function
module, CPU module or base module. Contact your
nearest Mitsubishi representative.
QCPU
function Ver.
B or later
1414
An error was detected on the Q bus.
This suggests an error for the special function module, CPU
module or base module. Contact your nearest Mitsubishi
representative.
QCPU
Rem
1415 Fault of the main and extension base module was detected.
1416 A bus fault was detected at power-on or reset.
This suggests an error for the intelligent function module,
CPU module or base module. Contact your nearest
Mitsubishi representative.
QCPU
function Ver.
B or later
1421 Hardware fault at the system management module AS92R.
This suggests a hardware fault. Contact your nearest
Mitsubishi representative.
Q4AR
1500
An instantaneous power supply interruption has occurred.
The power supply went off.
Check the power supply.
Rem
1510
The power supply voltage (5VDC) of either of the two power supply
modules on the power supply duplex extension base module
dropped to 85% or less of the rated voltage.
1520
The power supply voltage (5VDC) of the power supply module on the
extension base unit dropped to 85% or less of the rated voltage.
Check the supply voltage of the power supply module. If the
voltage is abnormal, replace the power supply module.
1530
The 24 VDC power supplied to the system management module
AS92R has dropped to 85% or less of the rated voltage.
Check the power supply.
Q4AR
1600
(1) Voltage in the CPU module battery has dropped below stipulated
level.
(2) The lead connector of CPU module battery is not set.
(1) Change the battery.
(2) If the battery is used for built-in RAM or for the back-up
power function, set a lead connector.
1601
Voltage of the battery on memory card 1 has dropped below
stipulated level.
Change the battery.
1602
Voltage of the battery on memory card 2 has dropped below
stipulated level.
Change the battery.
