Introduction

Non-Contacting Steering Angle Sensor Type 6002

Bourns Type 6002 Non-contacting Steering Angle Sensor is based on two magneto-resistive (AMR) sensor chips. Each of them converts an angle position of a permanent magnet into two analogue signals (one sine and one cosine signal). A highly effi cient algorithm allows for estimating the absolute angular position of a drive shaft that is connected to the device.Specifi cations

Specifi cations are subject to change without notice.

Customers should verify actual device performance in their specifi c applications.

CAN Protocol (Continued)

Rule to build the check sum: Temp_result = lower byte

(Angle position) XOR higher byte (Angle position) XOR (Angle speed) XOR

(Internal status) Check sum = higher nibble

(Temp_result) XOR lower nibble (Temp_result) XOR (Message counter)

An example of the message layout for a receive message is shown below.CAN Receive Message

Automatic Self-Test

The device checks the angular speed

value, which is limited to 1016 degrees per second. If this limit exceeded, the device sends an error message according to the CAN Transmit Message (page 1).

Command Word (CW)

Note:

To set up a new zero position, fi rst it is necessary to delete the old zero position.
