Safety Open

What does F059 mean?

Both of the drive's safety inputs (Safety 1 and Safety 2) are not enabled, indicating an open condition in the external safety circuit. This fault signals that the drive's integrated safety function detects an unsafe state, preventing motor operation until the safety inputs are properly closed and secure.
