Safety Circuit Fault

What does E.SAF mean?

The inverter output has been shut off due to a detected fault in the safety circuit or a functional safety-related issue. This can be caused by a broken wire in the safety input terminals (S1, S2, PC) when using safety functions, or general functional safety failures in Safety Communication models. This critical fault ensures machinery cannot operate unsafely.
