Other Parts Discussed in Thread: TMDSCNCD28069MISO, TMDSCNCD28027F
I have worked through most of the Instaspin-FOC labs using the TMDSCNCD28069MISO controlCARD with the HVMTR Eval Kit . The Instaspin-FOC solutions in the labs works great for my motor. I am now starting back on Lab2a but this time with the TMDSCNCD28027F controlCARD. After setting the "gMotorVars.Flag_Run_Identify” flag = 1 the motor identification process begins just like it does when using the TMDSCNCD28069MISO controlCARD but when the "gMotorVars.EstState" switches to the "Est_State_Rs" state the motor begins to make a high pitch squeal. I have been terminating the identification process at this point in time to prevent damage to the controller and motor.
Any ideas why the identification process difference exists between the TMDSCNCD28069MISO controlCARD and the TMDSCNCD28027F controlCARD?
