10.4 Set zero point (0x2046)
To set the zero point the sensor is rotated to the requested position and the current
position is set as "0". The value of the parameter "set zero point X and Y axes"
(index 2046h) is to be set to 1.
The sensor then calculates the offset to the zero point shift and saves it in the
permanent memory. From then on the offset is subtracted from the angle.
10.5 Terminating resistor (0x2045)
In bus topology a system is terminated with terminating resistors (120 Ω) at the
beginning and end. If the sensor is at the beginning or end, the terminating resistor
(index 2045h) integrated in the sensor can be activated by writing the value 1.
10.6 Set teach (0x2042)
Should it not be possible to integrate the inclination sensor into the measured
object so that the coordinate system of the sensor and object coordinate system
match, the teach function enables the creation of a new reference system.
The new reference system X
b
,Y
b
, Z
b
is defined so that its Z
b
direction corresponds
to the direction of gravitation at the teach moment. The X
b
direction of the
reference system results from the projection of the X
s
axis of the sensor to the X
b
Y
b
plane of the reference system.
The Y
b
axis then corresponds to the direction which is perpendicular to both the Z
b
and the X
b
axis.
The result of this is that at the teach moment the Xs axis must not be parallel to the direction of
gravitation. As long as the value for the index 2042h is 1, all angle indications are converted into the
new reference system.
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.
