Parameter storage device alarm

What does E.PE mean?

This function stops the inverter output if a fault occurs in the E2PROM device responsible for storing parameter settings. This issue might be related to an excessive number of write operations to the memory device, which can degrade its integrity.

• The non-volatile memory used for parameter storage is faulty.
• Attempted to write invalid data to the parameter storage.
• Power interruption during parameter writing operation.
• Wear or failure of the flash memory chip.
