This is one of my biggest fears, that I'll connect something backwards and have a light show. Since you were only using 56V, I think the IGBTs are fine. And as far as your capacitor goes, be sure to discharge it with a resistor before you charge it with the correct polarity. Idk what type you're using, but I have an SBE Power Ring 700D529 and I was told it's non-polarized so there shouldn't be a problem with it.
I think we have different versions of the controller board (21), so I can't speak for yours, but nothing on the schematic jumps out to me as vulnerable to reverse polarity damage.
For my encoder issue, I read through the AD2S1210 datasheet and if I understand correctly, the resolution is currently set to 10-bit but I need it to be 12-bit. This should allow it to emulate a 1024-line encoder instead of a 256-line one (right?). I can achieve this by taking Pin1 from GND and tying it to 5V. I'll try this out and report back, in case anyone runs into a similar issue in the future with the 2013 Leaf Motor EM57 (resolver 34VRX-1004C01S)
