SDO index 5D12 = 1000 mg
10.2 Configure measuring plane (SDO index 2048h)
The measurement categories are calculated by default from the measurement

axes of the internal acceleration measuring cell as follows:
v effective=√(vX

2

+ vY

2

+ vZ

2

)

a peak=√(aX

2

+ aY

2

+ aZ

)

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.
The three LSBs of the parameter for the configuration of the measuring plane

(SDO index 2048h) set which measuring axes are included in the calculation of the

final result. By default the characteristic values of the vibration measurement for all

3 axes are measured.
X axis active: bit 2 = 1

X axis not active: bit 2 = 0
Y axis active: bit 1 = 1

Y axis not active: bit 1 = 0
Z axis active: bit 0 = 1

Z axis not active: bit 0 = 0
