I try to evaluate AN12169 "PMSM Field-Oriented Control on MIMXRT1050 EVK", (Usinf FRDM-MC-LVPMSM board) but with different motor 45ZWN24-40, when I try to run with open loop scalar control or try to use motor identification tabs, it always report a fault immediately and never successful. Is there any body know why? I do not expect that all function well, but these two are very beginning of test, specially open loop scalar control should works without fault? I do not use HALL signals because AN12169 code is for encode feedback.
