Thanks for uploading the "Components, high voltage" file. But I wondered if anyone has the associated i3 Wiring Diagrams manual? If not does anyone know if "Service Manuals Online" is a safe website to purchase manuals from?
I'm looking for details on how the Park Actuator is driven. Mine looks ok ...

I tried using Gates Polychain Carbon belts but I found them just too noisy.
I considered making a silent chain replacement or perhaps a gearbox (transmission chain couldn't manage the speeds I needed).
But I have since come by a cheap Leaf motor and transmission, so I'm going to try that instead.

Thanks Johu, I'll try to source to a Gen 2 inverter.
I think I read on here somewhere that a Gen 2 inverter will run a Gen 1 motor (as the resolvers are the same).
I'd like to use the Gen 1 motor if I can as it would fit a little easier.
I presume there's no downside to doing that?

Is there any great difference between the Gen 1 and Gen 2 inverter power stages (other than physical appearance)?

I’m looking for maximum performance and wondered if it might be better to use the later Gen 2 rather than the Gen 1 which I have available.

OK so the voltage can be higher than 3.3 as long as the current is kept below the specified value.
Thanks for the clarification.

Just a point of clarification on the voltages of the AB encoder signals on the V2.0 board. I noticed the inputs being used (PA6, PA7) don’t seem to be 5V tolerant, yet it seems to me that they would be subject to 5V even at switch on... but I'm not an electronics engineer.
I’m using an open ...
