5.2.1.
Measuring axis and direction for Inclination
A single-axis inclinometer (vertical mount)
measures the inclination in the vertical plane over the full range 0-
360° (X-output). The default 0° position and the measuring direction are shown in Figure 9 - Measuring axis and
direction of 1-axis inclination.
Figure 9 - Measuring axis and direction of 1-axis inclination.
A dual-axis inclinometer (horizontal mount)
measures the inclination on both X and Y axis. Measuring range is
up to 90°. Due to the measurement principle, only one axis may tilt more than 45°.

– Measuring axis and direction of 2-axis inclination.
Cross-tilt error: when the cross axis (axis perpendicular to the measuring axis) tilts more than 45° during the
measurement, the measuring axis will be disabled. The sensor will send a fixed CAN output to indicate that the
sensor is now at a cross-tilt error position: 20000
d
(200°) for the measuring range ±180°, ±30°/ ±90°, and 40000
d
(400°) for the measuring range 0°-360°. In addition, an EMCY message will also be sent, in which the last 5 bytes
(00 00 00 00 01/02
h
) specifies the cross-tilt error on the X or Y axis
(→object 1002
