Inclination sensor JN

9.5 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 positive Y axis of the
sensor shows in driving direction of the excavator�

10 Other sensor functions
10.1 Device address (0x2000) and baud rate (0x2001)
In the case of a change the device address and baud rate do not become effective
until after a reset (reset application, reset communication or hardware reset)�
The inclination sensor from ifm is delivered with the device address 25 and a baud rate of 250
Kbits/s�
10.2 Limit frequency digital filter (0x2043)
With the sensor it is possible to make continuously arising angle values insensitive
to external interfering vibrations�
Using a configurable filter (digital FIR filter) interfering vibrations can be
suppressed� The limit frequency of the filter is set via the FIR filter step (index
2043h)�
