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.
