End of Line Configuration

Several parameters can be programmed via the single wire interface SICI end of line. No additional

programming pin is required, programming is performed via the output pin. Further details can be found in

the corresponding user manual.

5.1

Angle Base and Rotation Direction

An angle base value can be stored in the EEPROM. The output angle value is then referenced to this angle base.

It is also possible to define the rotation direction, i.e. for a given magnet rotation direction the output angle

value can either be selected to increase or decrease.

5.2

Customer ID

A total storage of 112bits in the EEPROM is reserved for customer specific data (e.g. customer module ID,

etc...). This data can be written via SICI interface. The read-out of the first 32bits of this data can be done with

the short serial message feature during operation as a slow message (only SENT and SPC interface). The

remaining 80bits can only be addressed via SICI and are not asccessible during operation.

5.3

Look-up Table

To increase the sensor performance and angle accuracy, a look-up table with 32 points can optionally be used.

Non-linearity errors coming for example from a misaligned magnetic circuit can thus be compensated. It is

necessary to have an external angle reference for this calibration. The sensor output values at predefined,

precise positions (0°, 11.25°, 22.5°, ...), given by the external reference, have to be determined. These 32 values

are stored in the corresponding EEPROM registers. The sensor performs a linear interpolation between these

reference points for the output value.
