Part Number: TMS320F28069M I'm running the lab13a with finely tuned bandwidth. In the beginning the motor shaft is stiff and holding position (I can barely move it with my fingers) but after some time I observer the torque_Nm variable drops and ST stops holding the position. The shaft is loose and when I make one revolution by hand I've got the 2002 position error. Please advise me what to check.
