Figure 9. Output PWM Signal After Start-up at 0º Unprogrammed Zero Position

Figure 10. Output PWM Signal After Start-up at Initial 0º with a Programmed Zero Position

After a startup of the AS5134 at the initial zero position the PWM signal indicates a permanent lock diagnostic. This behavior can be ignored

during elaboration of the PWM duty cycle. Figure 9 and Figure 10 show the different outputs depending on the OTP zero position programming.

After a mechanical movement (1º) the signal will change as shown in Figure 8. A startup at any other position will also look like as shown in

Figure 8.
