PMAC-Pack
22 Getting Started
Incremental Encoder Connection
Warning:
Remove power from PMAC-Pack before connecting encoders
Each axis of the PMAC-Pack has an encoder connection port. It also provides a +5V output and logic
ground for powering the encoder. Pinouts are shown in Figure 2-2.
When wiring, the encoder number does not have to match the axis number unless you want to use
position capture features, but it usually does. Later in the setup, we will insure that each PMAC "Axis" is
mapped to the desired Encoder. Connect the A and B (quadrature) encoder channels to the appropriate
terminal block pins. The PMAC-Pack is setup by default for either single-ended or differential Line-
Driver encoders. If you have a single ended signal, leave the complementary signal pins floating -- do not
ground them. If you are using an encoder with complementary open collector outputs, you must set E24-
27 on the PMAC-lite board to pins 2-3. The third channel (index pulse) is optional, although if you wish
to precisely home your motor, it is highly recommended to use an encoder with an index channel.
