Encoder wiring

The allocation of cable pairs for each encoder type is described in
this section. The encoders should be connected to FEN-31 with a
shielded instrumentation cable, preferably with twisted pairs. See
also the encoder manual for additional requirements. To prevent
the encoder inputs from being disturbed the cable shield must be
connected to the chassis.
Note: Do not route the encoder cables parallel to power (e.g.
motor) cables.
