synchronization
detected.
signal error
3000H
Boot function
The boot setting in the memory card
execution error
parameters is incorrect.
3001H
Boot function
When the boot function was executed, the
execution error
file format processing failed.
3004H
Boot function
When the boot function was executed, the
execution error
CPU built-in memory capacity was
exceeded.
Corrective action
• Take measures to reduce noise.
• Reset the CPU module. If the same error code is
displayed again, the possible cause is a hardware
failure of the CPU module, I/O module, intelligent
function module, or base unit. Please consult your
local Mitsubishi representative.
• Take measures to reduce noise.
• Reset the CPU module. If the same error code is
displayed again, the possible cause is a hardware
failure of the CPU module, I/O module, intelligent
function module, or base unit. Please consult your
local Mitsubishi representative.
• Review the interrupt setting in the module
parameter.
• Take measures so that no interrupt is requested
from the module with no interrupt setting exists in
the module parameter.
• Review the interrupt setting in the buffer memory
of the Intelligent function module.
• When the CC-Link IE Field Network module is a
synchronous target unit between unit, check the
connection status of the cable of CC-Link IE Field
module.
• Take measures to reduce noise.
• Reset the CPU module. If the same error code is
displayed again, the possible cause is a hardware
failure of the CPU module, I/O module, intelligent
function module, base unit, or extension cable.
Please consult your local Mitsubishi
representative.

Review the boot setting in the memory card
parameters.
Reset the CPU module and perform the boot
function again. If the same error code is displayed
again, the possible cause is a hardware failure of the
CPU module. Please consult your local Mitsubishi
representative.
• Review the boot setting.
• Delete unnecessary files in the CPU built-in
memory.
