Hello,I download MC9S12ZVML128_PMSM_Sensorlessuse and user my own motor, and modify the parameters in the software.but the speed  is wrong in open loop mode,I think it is the reason for the PI parameter, but I don't know the tuning principle of the PI parameter. I think the bandwidth and attenuation settings are wrong, but I don't know how to solve it.How can I do?
