SEW Eurodrive · MCBSM

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.

Complete Troubleshooting Guide

  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.
