(7) Pr. 343 Communication error count
You can check the cumulative number of communication errors.
Parameters
343
CAUTION
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.
(8) Output signal LF "alarm output (communication error warnings)"
During a communication error, the alarm signal (LF signal) is output by open collector output. The LF signal
can be assigned to the output terminal using any of Pr. 190 to Pr. 196 (output terminal function selection).
