MCF8315EVM: MCF8315EVM BDLC coded example

Hi Shahar Coden,

You can refer to runig guide to spin the motor. MCF8315/6 is having algorithm within the device and no code is required.

All you need to do is install the GUI and refer to EVM user guide to spin the motor.

Link to EVM: MCF8315EVM Evaluation board | TI.com

In this link refer to the documents marked.

Hi, 
 

I followed the tuning guide, and I encountered faults. I solve the errors with the tuning guide solutions ( for example 2.6.3 Abnormal BEMF Fault [ABN_BEMF] ) but the motor movement is incorrect not steady and jitter. 

I use the same BDLC motor I use in the universal_motorcontrol_lab_f28002x under Anaheim_BLY172S_24V motor and it work perfectly there 0.2 rpm as I required. 

I would like for help, 

Thanks! 

Hi Shahar Coden,

How much jitter are you seeing?

Can you save the JSON and share to me here?

Did you try tuning with MPET? Did you measure R, L, KE, Speed Loop KP, KI from MPET ?

Are you running in speed mode or Torque mode?

Please share your motor parameters.

What GUI version are you using? Motor Studo ?

Thanks and Best Regards,

Hi thanks for the fast response 

Its all in this post 

tell me if there is some information I can add that is missing 

thanks!

Hi Shahar Coden,

Can you run again quick spin with HZ mode not RPM.

If pole pair not there you program electrical HZ, with the information you are showing about RPM is 450 and Pole Pair is 21 so electrical HZ will be 157Hz.

Use this and try running quick spin again and check.

Thanks and Best Regards,
