3.3.5 Couplings
The right encoder is connected to the spring coupling which damps high accelerations but may cause
an oscillation until the moving parts are equalized.
Black round plate has a white dotted strap on it which you can read with the tacho sensor.

The left encoder is connected to the rigid coupling which eliminates any oscillations in regard to the
accelerating.
