16 Installation & Hook-Up
Connecting the AEC to the 1394
Connect the AEC to a 1394 GMC System using the encoder cable
(catalog number 1394-GR04) for each axis. This is a four foot cable
that connects Axis 0 Encoder or Axis 1 Encoder connector on the AEC
to the J3, J4, J5, or J10 encoder feedback connector on the 1394.
The 1394 interface circuitry requires 0.325A to operate. Any additional
devices connected to the 1394, such as incremental encoders, can
require an additional 0.2A per device (check your device for the
precise requirements).
To connect the encoder cables:
1. Insert the 12-pin plug labeled “REC/AEC” in the Axis 0 Encoder
or Axis 1 Encoder connector on the AEC.
2. Insert the 12-pin plug labeled “1394” in the J3, J4, J5, or J10
encoder feedback connector on the 1394.
3. Wire the remaining auxiliary power labeled “ENC. PWR” to the
5V DC power supply. The red wire is +5V and the black is a +5
common.
ATTENTION
!
The AEC does not support the removal or the insertion of
any connectors when under power. The power
disturbance can result in unintended machine motion,
loss of process control, or an electrical arc that can cause
an explosion in a hazardous environment.
IMPORTANT
This cable is polarity sensitive.
IMPORTANT
The AEC does not require power from the 1394 to
operate nor does it provide power to the 1394. However,
the 1394 requires a separate 5V power supply to run its
interface circuitry.
