Notes:
1. Total max. current 0.7A.
2. The inputs can be sine (sine and cosine) or square (phases A and B).
3. For single ended inputs use the ‘–’ input only.
The two non-connected wires per each encoder (Sine+ and Cosine+
should be floating, not grounded.
4. All the five GND pins (2, 20, 38, 12 and 30) are shortened. They
appear five times to make the wiring easier.
