I'm having trouble getting the resolver excitation working on my adapted Rev 2 board. I'm running Rev 4.87R-foc software, the encoder mode is set to Resolver, but I'm not getting any pulses at PD2, so obviously no excitation signal out. However, I don't have any other external I/O connected yet. Are there any error codes that would prevent properly initializing or starting the PD2 output?
BTW - I'd be very interested in having the resolver available for an ACIM as well. I'm planning to run a GM e-Assist motor/generator as an e-motorcycle motor, and it uses a resolver as its position sensor.

It will only become active once you enter run mode. Sine firmware supports resolver as well

Re: Resolver Excitation with V2 mainboard
Thanks, Johannes. I found an error in my board layout that is holding the overcurrent limit fault. Am I correct that this will prevent entering run mode?
Edit: Yes, adding a jumper in place of the missing track cleared the fault, and allowed me to put the board into Run. Moving on!
