Troubleshooting by Circumstance

When the Motion CPU module is not functioning normally, check for the applicable circumstance below, and troubleshoot
accordingly. If the ERROR LED is ON or flickering, use the engineering tool to remove the error factor.

When the READY LED of the Motion CPU module has turned OFF

When the READY LED of the Motion CPU module has turned OFF, check the following items.
Check item
The Motion CPU module is not mounted to the main base unit correctly.
The READY LEDs of other modules are ON.
After exchanging the power supply module, and turning ON the power
supply again, the READY LED turns ON.
(Also check power supply module on the extension base unit by
exchanging it.)
After exchanging the power supply module, and turning ON the power
supply again, the READY LED does not turn ON.
(Also check power supply module on the extension base unit by
exchanging it.)
If the READY LED does not turn ON after checking the above items, there may be a hardware error. Please consult your local
Mitsubishi representative.

When an error is displayed or flickering in the dot matrix LED

When an error is displayed or flickering in the dot matrix LED, check the following items.
Check item
"E" is displayed during initializing
"A00" is flickering.
"A01" is displayed.
"ER0" is displayed during installation mode.
"ER1" is displayed during installation mode.
"ER2" is displayed during installation mode.
"ER3" is displayed during installation mode.

6.5 Troubleshooting by Circumstance
Corrective action
Mount the Motion CPU module to the main base unit correctly.
The Motion CPU module is detecting a major error.
Exchange the Motion CPU module.
An error is occurring in the original power supply module.
Exchange the power supply module.
An error is occurring in a module other than the power supply module.
Mount each module one at a time, turning ON the power supply each time an
additional module is mounted.
The module that was mounted last when the READY LED no longer turns ON is
the module where the error is occurring. Replace this module.
Corrective action
A hardware error, or software error is occurring.
Exchange the Motion CPU module.
*:  is the error code
The operating system software is not installed.
Put the Motion CPU module in installation mode, and install the operating system
software.
There is an error in the operating system software file that was installed.
Reinstall the operating system software.
An access error of the SD memory card from which the operating system
software was installed is occurring.
Exchange the SD memory card, and reinstall the operating system software.
An error in the install file of the operating system software installed from SD
memory card is occurring.
Install the operating system software using another install file.
An error is occurring because installation of operating system version "05" or
earlier was executed on R64MTCPU. Operating system version "05" or earlier
cannot be installed on R64MTCPU. Install operating system version "07" or later.
An access error of the internal ROM of the operating system software installed
from the SD memory card is occurring.
Exchange the Motion CPU module.
An error has occurred with the license key file in the SD memory card.
Check the license key file on the SD memory card.
An error was detected during the built-in memory clear.
Exchange the Motion CPU module.
A watchdog timer error is occurring.
Check the error cause with "Motion CPU WDT error cause (SD512)", and remove
the error.
A self-diagnostic error (major/moderate/minor error) is occurring.
Check the description of the error code displayed with "MELSEC iQ-R Motion
Controller Programming Manual (Common)", or MT Developer2, and remove the
error factor.
*:  displays the 4-digit error code by displaying 2 digits at a time.
