Cause : Contract B Fault signal comes when multi-function input terminal (I17-I24) is set to 19 {External fault signal input: B (Normal Close Contact)}, the inverter turns off the output.
"Etb" fault indicate an external device tripped an alarm function or wiring is incorrect or multi-function contact input setting is incorrect.
- The terminal set to “18 (External fault- A)” or “19 (External fault-B)” in I20-I24 in I/O group is ON.
- Eliminate the cause of fault at circuit connected to external fault terminal or cause of external fault input.
