Hi,

 

I have a big Problem with my test bench AD_FMCMOTCON1-EBZ. When I was trying to get the system run, the “over current” LED flash up and I heared a buzz.

 

These are my settings:

- Zedboard xc7z020clg484-1

- AD_FMCMOTCON1-EBZ with Dynamometer

- Booting from SD-Card with the newest Image (no changes)

 

These are my steps:

- Add Power supply in the Low Voltage Drive Board

- Switch the Zedboard on

- Toggle the Emergency Stop Switch (S2) to UP

- press the Power Stage Reset

 

These are the results:

- Over current LED flash up

- hear buzz

- The Voltage on my power supply reduce and the current is max (looks like a short circuit)

 

That is what I have done before:

- The test bench works

- I run the Demo using foc_script.sh

- the motor spins

- I disable the run button in the Oscilloscope and enable it again after a few seconds

- The Motor starts to stutter

- So I shut down the power supply

 

Is it possible that I destroy my Drive Board. Without insert a higher voltage and using the test Demo?!

 

Can I do anything before I have to change the Hardware? Can I get my system back to the default settings?

 

I am really helpless, Thanks

Steffen
