Pr. 343 Communication error count
You can check the cumulative number of communication errors.
Parameter
Setting Range
343
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.
(8)
Output terminal LF "alarm output (communication error warnings)"
During a communication error, the alarm signal (LF signal) is output by open collector output. Assign the used terminal
