.
Use twisted pair cabling, connected as shown in
figure 3.3, for the cabling between the power
supply and the terminal strip. If you use cabling
with less than 2 twists/inch, it should be shielded.
Note that the shield should only be connected at
one end.
For best results, the power supply voltage should
be adjusted to provide 5 volts at the furthest
encoder.
Step 7. If your application requires them, mount the home
L/S, positive overtravel L/S, and negative
overtravel L/S on your machine. Overtravel L/S
should be normally closed devices. Fasten the
field wires from the limit switches to the terminal
strip. Typical field connections are shown in figure
3.4.
