   I test the demo code MTRCKTSPNZVM128->MC9S12ZVML128_PMSM_Sensorless which control algorithm is foc,and it works well.

   Now,I want to test the motor's performance on different frencenys of I change the PMFMODA  from 2500(20KHz,the bus clock is 50M and the core clock is 100M) to 5000. The speed is not correct any more!

   So,is there anything else I need to pay attention to?
