Inclination sensor JN 7.6 Angle definition (2044h) To be able to adapt the inclination sensor to the different applications as easily as possible, the measured inclination information is converted into different angle indications� The requested angle indication is set by selecting the respective option�...
Inclination sensor JN Value range for this option – Inclination value longitudinal (gradient angle): -90°…+90° – Inclination value lateral (angle of direction): 0°…360° Critical point With a gradient angle of 0° or 180° the sensor is in a horizontal position� In this position the second angle (angle of direction) is useless�...
Inclination sensor JN Explanatory example The different angle definitions will be illustrated using a simple example� An excavator moves up and down an embankment (illustration)� The embankment is angled at 30°� The inclination sensor is installed so that the x axis of the sensor shows in driving direction of the excavator�...
Inclination sensor JN 7.8.1 Set zero point (2046h) To set the zero point the sensor is rotated in the requested position� ► Write the value 1 (activate set zero point) to the object 2046h (zero point x and y axis)� >...
Inclination sensor JN The teach operation can, for example, be as follows: The measured object with the non-aligned inclination sensor is brought into a known horizontal position� In this position the teach function is carried out, thus defining the new reference system� All provided angle values then refer to this new reference system�...
