9 Other sensor functions
9.1 Node ID (SDO index 2000h) and baud rate (SDO index 2001h)
In the case of a change node ID and baud rate do not become effective until after
a reset (reset application, reset communication or hardware reset).
After a reset, all COB IDs will be recalculated and set according to the pre-defined
connection set → Chapter 11.2 COB IDs.
The inclination sensor from ifm is delivered with the node ID 10 and a baud rate of 125 Kbits/s.
The following baud rates [kBit/s] are supported: 10, 20, 50, 125, 250, 500, 800 and 1000.
9.2 Limit frequency digital filter (SDO index 2043h)
With the sensor it is possible to make continuously arising angle values insensitive
to external interfering vibrations.
Using a configurable low-pass filter (digital FIR filter), interfering vibrations can
be suppressed. The limit frequency of the filter is set via the FIR filter step (SDO-
Index 2043h. In the sensor, several pre-set filter steps (0.5…10Hz) are available.
9.3 Set zero point (SDO index 2046h)
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 and y axis" (SDO
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.
9.4 Terminating resistor (SDO index 2045h)
In bus topology a CANopen 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 (SDO index 2045h) integrated in the sensor can be activated by writing the
value 1.
