The Main and Personality Boards
The QD-4000 consists of two unique printed circuit boards: The Main Board, and
the Personality Board. The Main Board, the larger of the two is the backbone of
the system, hosts primarily the output power amplifiers, the majority of
connections, and heat-generating devices. The Personality Board, the smaller of
the two, hosts the control-loop, notch filter, and the diagnostic connector. A
“Board Pair” MUST be used for the servo to operate.

Connect
Guide
Before connecting the servo drive(s) please read Section 2.
¾
Adjust your dual voltage supply within the proper range of +/- 15V to +/- 24V
before connecting the power cables.
¾
After adjustment, turn off the power supply before making any connections to the
servo drive(s).
¾
The servo drive(s) should be properly mounted to a sufficient heat sink.
¾
Galvanometers should be mounted properly to avoid mirror collisions.
¾
Connect the Position Detector Cable from the Galvanometer Position Detector
Connector (white, 5 Pin) to the Servo Driver Board (J1). Repeat if there is more
than one Galvanometer.
¾
Connect the Scanner Drive Coil Cable from the Galvanometer Drive Coil
Connector (black, 3 Pin) to the Servo Driver Board (J6). Repeat if there is more
than one Galvanometer.
¾
Connect the Power Cable(s) from the Power Supply to the Servo Driver Board(s)
(J7).
¾
Connect the Command Input Cable(s) from the function generator or host system
to the servo drive board(s) (J3). If using a single ended signal, be sure to attach
the (-) negative and ground pins together at the servo drive command connector.
If using a signal from a differential source, Pin 1 is the positive (+) command
input, Pin 2 is the ground (-) command, and Pin 3 is the negative (-) command
input.
