FX5U 4C1BH — CPU module backup/restoration function error
Warning — monitor
CAUSE
Why does it occur?
• The data restoration function was executed to the CPU module whose status (such as programs, parameters, and file structure) differs from that of when the data backup function was executed.
REMEDY · Step by step
How to fix it?
• Match the CPU module status to the one at the time of backup, and execute the function again. • Store 0 (All target data) to SD954 (Restoration target data setting) and execute the automatic restoration.
Do not reset repeatedly before identifying the cause. Repeated resets while ignoring a trip/alarm can cause secondary damage (IGBT failure, motor winding damage, etc.).
