7. Connectors
For your convenience, a set of mating connectors and pins for the Power, Command
Input, and Diagnostic Output connectors ship with every driver board.
7.1 Power Connector (Main Board - J7)
The mating connector is a Molex 39-01-4031 or 39-01-4030 connector with (3)
Molex 39-00-0183 or 39-00-0184 pins. The pins should be used with AWG 22-28
wire.
The power connector (
J7)
is used to deliver the appropriate voltage to the servo driver
board. Pin 1 is the positive supply voltage. Pin 2 is the ground. Pin 3 is the negative
supply voltage.
A power supply with sufficient output current should be used. The output current
required depends on the supply voltage, galvanometer model, mirror load, and
command waveform and duty cycle. Lower supply voltages, larger galvanometers,
larger mirrors, and more demanding waveforms and duty cycles will require more
current. It is a good practice to setup your application with a laboratory power supply
and measure the required current during the most demanding application your system
can run. Then select a power supply appropriate for your application.
The QD-4000 has two generous output capacitors, which supply instantaneous peak
current to the output drive amplifiers and lower the peak output requirements of your
system power supply.
