RS-485 timeout

What does 43 mean?

Stop without inhibit due to an interruption in the connection between the inverter and the PC. This prevents remote monitoring or control via RS-485, leading to a loss of communication capability.

• Communication timeout detected on the RS-485 serial port.
• No response received from a connected device on the RS-485 network.
• Incorrect baud rate or communication settings (e.g., P7-01, P7-02).
• Physical wiring issue or termination problem on the RS-485 bus.

Click steps to track your progress.

1. 1

   Check the physical RS-485 connection cable between the inverter and the PC for integrity and proper seating.

2. 2

   Verify communication settings (baud rate, parity, data bits) on both the inverter and the PC are matching.
