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)�
10.3 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�
10.4 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�
10.5 Set teach (0x2042h)
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

is defined so that its Z
