Wiring Encoders
When you wire encoders, use a single, continuous, shielded cable
segment. Wire the cable directly from the encoder to the termination
panel.
Cable length depends on the power supply for the user-side. Voltage
at the encoder must be within the voltage requirement limits specified

ATTENTION
!
To avoid unpredictable operation of your SLC Servo
Module, connect the +5V COMM to the +24V COMM.
If voltage sources are coming from two separate
isolated power supplies, tie the +24V return to the
+5V return.
