- Section of the railway vehicle or a part thereof or joints thereof are located.
- Driving speed to be adjusted. As the speed increases, for example, these values or ranges can be set higher or narrower. At higher driving speeds, it can be assumed that, for example, the rotational speed becomes greater and this is also normal. Accordingly, limit / reference values (ranges) can be set higher.
