The figure below shows actual screen shots from an oscilloscope for the example above.
The enable window is displayed in ch1 and the pulses in ch2:
At position 5 mm, the position compare output functionality becomes active and the
first pulse is generated. Then, pulses are generated every 2 µm which equals a time span

This second picture shows a zoom of the second pulse. The duration of the pulse should
be 200 ns, however the pulse duration can be longer as the rising edge is related to the
