Wiring Your 1394 Analog Servo System 5-5
Connecting AQB and SCANport
Cables
The 1394 Analog Servo system module provides connections for
AQB encoder feedback outputs to external positioning controllers and
SCANport. The figure below shows the locations of the AQB and
SCANport connections.

Analog Servo Encoder (A Quad B) Wiring
A Quad B uses resolver feedback to emulate an encoder differential
output for motion controller position feedback. It requires a user-
supplied reg5V DC (1 amp maximum) at terminal 3. Wiring a
+5V DC power supply to one axis will provide power to all four ports
(parallel connection), therefore, you only need to connect the +5V
DC power supply to one AQB port. For the 1326AB series motors,
the motor mechanical cycle is 2048 pulses per revolution (PPR). In
addition, two marker pulses are generated per mechanical cycle. For
the 1326AS series motors, the motor mechanical cycle is 1024 PPR.
In addition, one marker pulse is generated per mechanical cycle.
Refer to Figure 5.3 for connector locations. We recommend one
1394-SA15 (from the 1394 AQB output to the user-supplied control)
cable per axis.
