Appendix 1 Error Codes Appendix 1.3 List of error codes (1000 to 1999)
1009
[MAIN CPU DOWN]
• The voltage waveform that is outside the
specification is applied to the power supply
module, and an error is detected.
• A failure was detected on the power supply
module, CPU module, main base unit, extension
base unit or extension cable.
• When using the redundant base unit, the
redundant power supply module failure in both
systems and/or the redundant base unit failure
are detected.
■Collateral information
• Common information: -
• Individual information: Failure information
(QnUDVCPU only)
■Diagnostic timing
• Always
• Correct the voltage waveform applied to
the power supply module.
• Reset the CPU module and run it again. If
the same error code is detected again, the
cause is a failure of the power supply
module, CPU module, main base unit,
extension base unit, or extension cable.
Please consult your local Mitsubishi
representative.

[CPU UNIT DOWN]
• A failure was detected on the power supply
module or CPU module.
• The voltage waveform that is outside the
specification is applied to the power supply
module, and an error is detected.
■Collateral information
• Common information: -
• Individual information: Failure information
■Diagnostic timing
• Always
• Correct the voltage waveform applied to
the power supply module.
• Reset the CPU module and run it again. If
the same error code is displayed again, the
cause is a hardware failure of the power
supply module or CPU module. Please
consult your local Mitsubishi
representative.
LCPU
1010
[END NOT EXECUTE]
Entire program was executed without the
execution of an END instruction.
• When the END instruction is executed it is read
as another instruction code, e.g. due to noise.
• The END instruction has been changed to
another instruction code somehow.
■Collateral information
• Common information: -
• Individual information: -
■Diagnostic timing
• When an END instruction executed
• Take noise reduction measures.
• Reset the CPU module and run it again. If
the same error code is displayed again, the
cause is a hardware failure of the CPU
module. Please consult your local
Mitsubishi representative.
RUN: Off

1020
[SFCP. END ERROR]
The SFC program cannot be normally terminated
due to noise or other reason.
• The SFC program cannot be normally
terminated due to noise or any similar cause.
• The SFC program cannot be normally
terminated for any other reason.
■Collateral information
• Common information: -
• Individual information: -
■Diagnostic timing
• When SFC program is executed
• Take noise reduction measures.
• Reset the CPU module and run it again. If
the same error code is displayed again, the
cause is a hardware failure of the CPU
module. Please consult your local
Mitsubishi representative.
