External Fault at Terminal S3

What does EF3 mean?

This fault is triggered when an external condition connected to multi-function digital input terminal S3 activates the Drive's external fault function. The Drive will stop according to its programmed response (ramp, coast, or fast stop). This indicates an issue with the external device or process monitored by S3, potentially leading to unsafe operation if misconfigured.
