Pr. 343 "Communication error count"
The communication error occurrence count can be checked.
Register Definition Read/Write Remarks
40501 Faults history 1 Read/Write
Data is 2 bytes and so is stored in "H00

".
The lowest 1 byte can be referred to for the error code.
(For details on error codes, refer to page 6-5.)
The faults history is batch-cleared by writing to register
40501.
Set any value for the data.

Tab. 5-298: Inverter type monitor
NOTE When a 32-bit parameter setting or monitored value is read and the read value exceeds HFFFF, the
reply data will be HFFFF.
Parameter Setting range Minimum setting range Initial value
343 (Read only) 1 0
Tab. 5-299: Number of communication errors
NOTE The communication error count is temporarily stored in the RAM memory. The value is not stored
in EEPROM, and so is cleared to 0 when power is reset and the inverter is reset.
