This block
• configures supervision of external
faults by defining the source (for
example, a digital input) for external
fault indication signal
• selects the reaction of the drive
(alarm; fault; continuation at safe
speed in some cases) upon
situations like local control
communication break, motor/supply
phase loss, earth fault, or Safe
Torque Off function activation
• shows the codes of the latest faults,
the time at which the active fault
occurred, and the alarm words.
