11 Parameter setting of the vibration measurement
If the measuring method is set to vibration measurement (ISDU index 4106 = 1),
the sensor can be adapted to the respective application via the following IO-Link
parameters.

If the vibration measurement is active, the sensor provides two different
characteristic values instead of the angle values.
The X angle value now corresponds to the effective value of the vibration velocity
(v
eff
[1/10 mm/s]), the Y angle value to the maximum vibration acceleration (a
peak
[mg]).
11.1 Configure measuring plane (ISDU index 4107)
The measurement categories are calculated by default from the measurement
axes of the internal acceleration measuring cell as follows:
v effective=√(v²x+ v²y+ v²z)
a peak=√(a²x+ a²y+ a²z)
The definition of the coordinate system of the acceleration measuring cell
corresponds to the coordinate system of the sensor. The mounting plane
corresponds to the xy plane and the z axis is perpendicular to the mounting plane.
