SinCos vs Incremental encoder

- See and hear the difference between interpolated SinCos encoder and incremental encoder (the same encoder without interpolation). In SinCos mode, the interpolation factor is 256x which yields over 1 million counts per revolution (20 bits per rev). The motor is driven with Granite Devices IONI Pro servo drive with native Sin Cos encoder support.
Super !
With is a lie! It`s one motor. One encoder. Difference in PID!!! Сorrect setting.
The motor is indeed the same, but in the first one he runs it as an incremental mode (no sin-code interpolation) this only results in a relitively small pulse count (4096) per rev. When you interpolate the sincos signals you can get an insane resolution, giving your PID loop much more data to work with. It's a bit more complex then that. I can't see them lying here.
