FX5U 4C01H — Data logging function error
Warning — monitor
CAUSE
Why does it occur?
• The result file cannot be written to the target memory because the SD memory card is write-protected or the folder/file structure is incorrect.
REMEDY · Step by step
How to fix it?
• Unlock the write protect switch of the SD memory card, and write the result file again. • Check that the SD memory card is not damaged. • Check that the file/folder to be used in the SD memory card has not been deleted.
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.).
