When wiring the QD63P6 and an encoder, separate the power supply cable and
signal line.
The following diagram shows an example of wiring with Phase A. (Wire Phase B
as well).

Since the current
through the shielded
twisted pair cable flows
in the same direction,
canceling effect does
not work, which results
in susceptibility to
electromagnetic
induction.
