Frequently Asked Question

We use a QG65N-KDXYh-090-CANS-C(F)M-2d as an example.
The SDOs in the example is supposing the Node ID is 01h. If your sensor has other Node ID, please change the CMD to 0x600 + Node ID. For example, 605 if your device has a Node ID of 05h.

Some preparation work first. You'll need
1. the CANS inclination manual:
2. the CRC generator.
3. the CRC manual.

Now we can start.

1. Mount the sensor at your wished zero position. Pay attention, for 2 axes horizontal mounting sensor, there is a 7.5° offset limit, which means the X or Y axis should not tilt more than ±7.5° than the default zero position. If you mount the sensor at a wrong position, the zero adjustments will fail.
   
   
   
   
   
   
   
2. Put the sensor in "pre-operational" mode.
   
   
   
   
3. Go to the CANS inclination manual, we can find the CAN Object Dictionary Entries for ±90h devices on page 15. (If you have one axis sensor, go to page 13)
   
   
4. Write 01h, 02h, or 03h* to object 0x300Fh-01h, depending on the type of sensor, and on which axis to zero.
   
   
   
    
   
   
5. Check if the zero adjustments is successful by reading the same object 0x300Fh-01h. If you read 00h, it means you have zeroed the sensor successfully. If you placed the sensor at a position where the zero offset is over the 7.5° limit, you will get the error code:
   FFh = X-axis over the limit, zero failed.
   FEh = Y-axis over the limit, zero failed.
   FDh= both X and Y over the limit, zero failed.
   
   
   successful:
   
   failed:
   
   
   
6. As zeroing affects safety, it affects the CRC-(checksum)-a calculation that must be re-calculated as follows:
   
   1. read the new offset values from object 0x6200h-01h (longitudinal / X) and -02h (lateral / Y)
      
      response:
      The new offset on X axis is 0xFFE2
      
      
      response:
      
      The new offset on Y axis is 0x1B02
      
      
   2. write the new offset value in de CRC generator program, together with node-ID, sensor type, and firmware version. (the CRC manual explains how it works)
      
      The new CRC for centering is 0xA086.
      
7. Write the new CRC code for centering into object 0x63FF-01h. (The information over CRC centering is on page 13.)
   
   
   
   
8. Write “A5h” to object 0x63FEh-00h to enable the Pre-set configuration signature.
   
   
   
   
   
9. Save the CRC, by writing “save” in ASCII Or “65766173h” to object 0x1010h-01h.
   
   
   
   
   

10. Set the sensor to operational state

Now the sensor is centered and should provide SRDO’s with axis information.
