Pr.343 Communication error count
• The communication error occurrence count can be checked.
• 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.
Alarm (LF) signal output (communication error warning)
• During a communication error, the Alarm (LF) signal is output by open collector output. Use
to assign the function.
• The LF signal can be assigned to an output terminal by setting Pr.195. Changing the terminal assignment may affect other
functions. Set parameters after confirming the function of each terminal.
