Cheap Focer Troubleshoot DRV

Hi Vesc community,

I assembled the cheap focer myself, in an industrial environment. On first startup,

I ran the motor configuration wizard. The attached brushless motor twitched a little bit (about 1 sec),

then stopped and the red light flashed 3 times. Untila a few seconds it tries again, but the motor won't

rotate correctly.

When I type fault in console, I get the DRV Fault.

How can I measure through the vesc, to find the fault?

And when do I have to bridge on/off pins on vesc?

(I limited the current to 1 Amp with 11 Volts when testing and it draws about 80mA in idle and

I hear a weired high frequency noise coming from the vesc)

(I have an oscilloscope, multimeter smd reflow station and some electronical knowledge)

Thank's in advance for every answer, I'm stuck on this problem for a few days.
