I sent an email to the JMC servo sales dept. and asked if it was 1000 ppr or 4000 ppr with quadrature decoding. We'll see what they say.
I looked up some clearpath SDSK Nema23 frame servos for a comparison.....I was surprised to see that their standard achievable resolution was 0.450 degrees.
So 360/0.45 = 800. Yeah, that's not great. The thing that struck me about that was our conversation about how the larger number of ppr doesn't just increase the resolution, it also makes the motion smoother, better. Well, the Clearpath servos have great motion. Everyone says so. That makes me think that there is some "special sauce" in the brains of this thing, and perhaps that is a more recent development for integrated servos compared to more traditional models. JMC servos might be similar.
Clearpath does have an enhanced option which brings it down to 0.057 deg, it just costs a bit more. The JMC 400W have alot more rated torque than any of the Clearpath Nema 23 frame I looked at. Note, I said rated.
