Hello! I don't think there's a difference between PMAC and brushless DC. Well, I think sometimes PMAC wants a pure AC waveform for best results, and brushless DC wants trapezoidal? But I'm not sure. Also, both motors work fine with an AC waveform.
If it's a permanent maget motor, and you have an encoder, you shouldn't need different firmware. You might just have to set the number of pole pairs, motor type (permanent magnet with encoder) etc.
That would be absolutely awesome to go through the whole tuning process and everything. That's something that I should have done and never got around to doing.
