I test  MC9S12ZVML128_PMSM_Sensorless_SingleShunt(AN5327) application.


but, there are OverPhaseACurrent fault as soon as I power on the board. Even if Motor UVW line is off.


It do not enter Ready state. It only stay Fault state.


I already tested MC9S12ZVML128_PMSM_Sensorless application(Dual shunt) under same condition.


It works well. It enter Ready state. no problem.


Could you check the MC9S12ZVML128_PMSM_Sensorless_SingleShunt(AN5327) application?


What's problem?
