This section describes wiring an encoder and controller to the QD63P6.
4.4.1
One of the conditions to maximize the QD63P6 functions and make the system high-
reliable, the external wiring has to be laid so that the QD63P6 becomes less subject to
noise.
This section describes the precautions on external wiring.
(1) Inputting a signal of different voltage may result in a malfunction or
(2) For 1-phase input, always perform pulse input wiring on the phase A
(3) When pulse status noise is input, the QD63P6 may miscount.
(4) Take the following measures against noise for high-speed pulse input.

side.
(a) Always use a shielded twisted pair cable and provide grounding.
(b) Wire the shielded twisted pair cables so as not to be in parallel with wires causing
much noise such as power lines or I/O wires while keeping a distance of at least
150 mm (5.91 inch) between such wires. Also install the shielded twisted pair
cables as short as possible.
