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?
