Functional principle

The rotational speed is detected by periodic

damping of the integrated inductive sensor. This

can be accomplished via metal targets or teeth

on the monitored shaft. The pulse sequence

generated is compared to an adjustable

reference value in a comparator circuit If the

rotational speed is below the reference value,

the output is switched off (0). If the reference

value is exceeded, the output is switched on

(1). The start-up time delay (A?) is triggered by

applying voltage to the device and closes the

output for 5 s (start-up time of the drive).
