Power Wiring 4-13 MN765
4.13 Encoder Installation
The Encoder Board (Daughter FDBK) is installed in the Feedback Module Slot 3 shown in Figure 4-11. Encoder
connections are made at that board. Use 16AWG (1.31mm2) maximum. The Encoder Board can p5VDC or
+12VDC (jumper selectable) encoder power. The factory setting for this jumper is +5VDC power. If an external
power supply is used for encoder power, the J1 jumper must still be used to scale the input signal levels correctly.

Connect all cable shields to pin 1 or 16.
For single ended encoder connections, connect
all unused inputs to pin 9. Pin 9 is an isolated
ground, do not connect to any other ground.

Encoder Output
Important: An isolated power supply provides encoder power. Do not connect encoder Power to encoder case. Encoder
performance will be compromised.
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+) (2, 4, and 6 respectively). A-, B- and C- are then connected to common at 9 as shown in
Figure 4-12.
