It is on a scale. A resistance of any range you like. For example, 0-10TOhm, 0-10GOhm, 0-10Meg, etc.

I'm done PI loop tuning the PMSM motor at 12 volts. A 5 amp step converges in around 0.5msec-1msec.

Now I'm going to figure out what the offset is from index for which Id = NONZERO, Iq = 0 doesn't cause the motor to turn. Then, save that offset for the life of the motor/encoder pair. PMSM is so much easier than ACIM. it will be very easy to include support for both types of code. I can't wait to see it spin tomorrow.
