Hi Rick,
Getting closer. Seems that I am fighting inrush overcurrent (with a tiny motor).
Once the command is sent I hear a very short click.
So by reducing ABVref voltage and ramping up current regulation (A10,A11,A12) I can let the motor spin.
If A10,A11,A12 are set in the first place, inrush current trips OCP.
Obviously I have to look deeper into current regulation and the current sense resistor.
Cheers
Juergen
