Hi,I have a problem with the sensor. the hall_b sensor shows the wrong value (205) in the bldc openloop app (Demo from matlab). Can you help me please?

best regards

Hello,

It looks to me like a broken cable from sensor.

Could you measure the Hall B cable and eventually the sensor output via scope?

best regards,

Peter

hi, thank you for your answer. But in MCSPTE1AK144_BLDC_6Step with S32K_BLDC_Sensorless.pmp i can see all Hall sensors (A B C). the problem only appears in the mbdt with bldc demo.

best regards
