Safety Function Fault

What does SAFF mean?

A general safety function fault. This indicates that a critical safety-related event or malfunction has occurred, leading to a safe stop or shutdown. The specific cause requires further investigation of safety registers like SFFE or SAF1 for detailed information. This is a high-priority fault requiring careful investigation.
