Fasten the field wires from the encoder to the
terminal strip. Typical field connections are shown
in figure 3.2. If you are not using the marker pulse
in your application, you can leave the "Z" and "Z"
inputs disconnected.
Use twisted pair cabling, connected as shown in
figure 3.2, for the cabling between the encoder
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.
If a feedback encoder is connected to the gearing
reference of another axis, jumper the connections
on the terminal strip.
Step 6.
Mount the external 5 volt power supply for the
encoders. The current rating must be sufficient for
all of the encoders that will be powered from the
supply as well, as the module. Check the
specifications of the encoder you will be using.
Fasten the field wires from the power supply to the
terminal strip. Typical field connections are shown
in figure 3.3
