MCF8315EVM: The motor will not turn and the motor drive wires never get driven, how do diagnose the fault

HI,

Thanks for posting your question, I am out of work today, I will respond to you by tomorrow.

Thanks and Best Regards

Hi John,

Can you please confirm whether you applied all the configuration ? 

Can you share Motor data sheet and JSON file you have used?

Thanks and Best Regards

Maxon EXC FLAT EXCFL32S KLA STD 24V.pdf

I have added the motor data sheet and json file

I believe I have applied enough configuration to get the motor moving

Maxon EXC FLAT EXCFL32S KLA STD 24V.pdf

I have added the motor data sheet and json file

I believe I have applied enough configuration to get the motor moving

I can only see the pdf file and not the json config file but I have added it several times

Hi John,

Thanks for sharing the details, I will verify this and reply.

Thanks and Best Regards

Hi John,

I looked at JSON file and I also want to check about versions of GUI and EVM which you are using.

Before getting into details of my question, I presume you are using the MCF8315A GUI which is not based on the new GUI format MOTOR STUDIO.

I see SPD_LOOP_KP, SPD_LOOP_KI are zero which can trigger MPET or no torque command sing PI loop of speed loop don't generate any torque reference.

I would recommend you to migrate to Motor studio, I will share reference JSON file to run the MPET and test it.

You need to update the EVM with MOTOR STUDIO compatible firmware as per this link 

(+) [FAQ] Motor Studio GUI - EVM Firmware Compatibility - Motor drivers forum - Motor drivers - TI E2E support forums

STEP1: Update EVM with new FW

STEP2: Install MOTOR STUDIO

STEP3: Test MOTOR STUDIO detects the device automatically.

Once  you confirm all set, I will create  a reference JSON which runs MPET and then continue testing.

Thanks and Best Regards

Venkatadri S

The board version is MCF8315EVM Rev 1.0    M0070-001

MCF8315A_GUI Ver 1.0.1 

Hi John,

Understood, you can update to MOTOR STUDIO GUI, let me know once you are able to update.

Thanks and Best Regards

Hi Venkatadri

Things are a lot better  now.  I have been able to get the motor to drive at about 200rps.  Though it is not very stable and takes a long time to ramp up to speed.

Any suggestions to improve this would be welcome.

Thanks

John
