External Fault (Terminal S6)

What does EF6 mean?

This fault indicates that an external device triggered a fault via the Multi-Function Digital Input (MFDI) terminal S6, or there is incorrect wiring to S6, or the terminal is incorrectly configured for an external fault despite not being in use. This causes the drive to halt operation based on an external signal, potentially stopping connected machinery.
