F00051 Parameter EEPROM Fault
Reaction: OFF 2
Acknowledge: Quit fault eg. via DI2
Cause: Read or write failure while access to EEPROM.
This can also be caused by the EEPROM being full, too many parameters have been changed.
Remedy: • Must be Power Cycled to cancel this bug as some parameters may not be read correct.
• Factory Reset and new parameterization, if power cycle does not remove fault
• Change inverter control unit
• Change some parameters back to default values if the EEPROM is full, then power cycle
Note: • r0949 = 1: EEPROM Full
• r0949 = 1000 + Block No: Reading data block failed
• r0949 = 2000 + Block No: Reading data block timeout
• r0949 = 3000 + Block No: Reading data block CRC failed
• r0949 = 4000 + Block No: Wrinting data block failed
• r0949 = 5000 + Block No: Writing data block timeout
• r0949 = 6000 + Block No: writing data block verify failed
• r0949 = 7000 + Block No: Reading data block at wrong time
• r0949 = 8000 + Block No: writing data block at wrong time
• r0949 = 9000 + Block No: Factory Reset did not work becuase restart or power failure
