*) The status B then only leads to a safe shut down when the option "broken shearpin mon-
itoring" is activated (B2). If the option is not activated (B1), then only the bit 9 of the dia-
gnostic word is set.
**) The output speed is "1" when the configured overspeed is not exceeded.
***) Input = 1: Speed monitor detects impulses
Input = 0: Speed monitor detects no impulses

7.3 Faults - malfunctions
Monitoring the direction of rotation: If an internal error occurs or there is an error due to a
defective incremental encoder ("FAULT" LED illuminates or flashes), an incorrect direction
of rotation may be signalled for approx. 500ms.
