P.343 Communication Error Count

You can check the cumulative number of communication errors.
Table 129: P.343 Communication Error Count
Parameter
P.343
Note: The number of communication errors is temporarily stored in RAM. It is not stored in EEPROM, so
performing a power supply reset or a VFD reset clears the value to 0.

Output Terminal LF: Alarm Output (Communication Error Warnings)

During a communication error, the alarm signal (LF signal) is output by the open collector output. Assign the
used terminal using P.190, P.192, or P.197 (output terminal function selection).

Note: The LF signal can be assigned to the output terminal using P.190, P.192, or P.197. Changing the
terminal assignment may affect the other functions. Make the setting after confirming the function of
each terminal.
