How to troubleshoot configuration or communication error on Gefran Inverter?
- SShannon LynnSep 2, 2025
If the Gefran Inverter displays an error in the configuration stage or communication error, and if the first digit to the left of “H” in the alarm sub-code is equal to 0, the error relates to a communication problem. If the first digit to the left of “H” in the alarm sub-code is other than 0, the error relates to a configuration problem. For configuration errors, check the configuration of the Bus communication, Bus type, Baudrate, address parameter setting. For communication errors, verify wiring, resistance of terminations, interference immunity, timeout settings.
