Register Definition Read/write Remarks
40501 Fault history 1 Read/write
Being 2 bytes in length, the data is stored as
"H00".
Refer to the lowest 1 byte for the error code.
Performing write using the register 40501 batch-
clears the faults history.
Set any value as data.
40502 Fault history 2 Read
40503 Fault history 3 Read
40504 Fault history 4 Read
40505 Fault history 5 Read
40506 Fault history 6 Read
40507 Fault history 7 Read
40508 Fault history 8 Read

NOTE
The number of communication errors is temporarily stored into the RAM. As it is not stored into the EEPROM
performing a power supply reset or inverter reset clears the value to 0.
