(7) Pr.343 Communication error count
You can check the cumulative number of communication errors.
Parameter Setting Range
343 (Reading only)
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 drive unit 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
using any of Pr.190 to Pr.192 (output terminal function selection).

NOTE
The LF signal can be assigned to the output terminal using any of Pr.190 to Pr.192. Changing the terminal assignment
may affect the other functions. Set parameters after confirming the function of each terminal.
