Hi,

we are editing the program sensorless program in " C:\ti\controlSUITE\development_kits\DRV830x-HC-C2-KIT_v105\PM_Sensorless" .In this program how i can introduce a factor to limit the output current,for example if i specified the output maximum current is 10A then the output should not cross that limit.

Thank you

    If the motor was running with speed close loop in Level7, you can limit the torque current by setting the max/min value of speed PID as below.
    pid1_spd.param.Umax = _IQ(N);
    pid1_spd.param.Umin = _IQ(N);
    N = Iq(maximum)/Ib; Ib is the BASE_CURRENT in xx-Setting.h.
