NOTE:

Any possible voltage drop in the encoder supply (5 V ±5%) can be compensated with the aid of the Sense cables. If the Sense cable is not used, pins 12 and 13 (+/- Sense) should be connected to pins 3 and 8 (5 V / Ground) on the encoder cable end.

The encoder supply is executed as short-circuit-proof.
