Encoder Cable Connection
Encoder cable must be separated by at least 3” from parallel runs of power wires.
Encoder cables that cross power wires must cross at a 90° angle only. Encoder wires
must be #22 AWG (0.34mm
2
) minimum, 200 feet maximum length and must have an
overall shield.
Note: Be careful not to pinch the wires’ insulation in terminal. If insulation is caught
in screw terminal, proper electrical connection will not be made. Encoder will
not operate properly.
1. Feed the control end of the cable through one of the holes in the control case
so connections can be made inside the control.
2. Differential Connections
Connect the cable braided shield to J1-30 at control end.
Connect the cable ends as follows: (See Figure 3-2.)
Encoder End
Control End
A J1-23 (A)
H J1-24 (A)
B J1-25 (B)
J J1-26 (B
)
C J1-27 Index(C)
K J1-28 Index(C)
D J1-29 (+5VDC)
F J1-30 (Common)
E N/C
3. Single Ended Connections
Differential inputs are recommended for best noise immunity. If only single
ended encoder signals are available, connect them to A, B, and INDEX (C)
(J1-23, J1-25 and J1-27 respectively).
