External Terminal Low Signal
SEW Eurodrive · MOVIFIT SC
What does 26 mean?
This fault is triggered when a low signal is detected on a specific terminal that has been configured for the '/External fault' function, primarily when the MOVIFIT unit operates as an SBUS slave. This indicates an issue with an external device connected to this terminal, signaling a fault condition from that external source. The low signal could be due to wiring issues, a faulty sensor, or an active fault in the connected external equipment, causing the MOVIFIT unit to stop operation.
