1. Introduction
This manual covers the installation and use of the QuantumDrive-4000 for single axis
and two axis applications.
The QuantumDrive-4000 (QD-4000) servo driver board is specifically designed to
control a wide range of galvanometers and loads under a variety of command input
conditions. The board incorporates the latest in servo technology along with system
safety and status features.
The QD-4000 uses high quality components to achieve fast servo response with low
noise and thermal drift. Generous output capacitors provide instantaneous current to the
output drives, which improves performance and reduces power supply demands.
The QD-4000 is a class 1, Position, Integral, and Differential (PID) servo controller
along with several other terms designed to maximize performance and allow for
flexibility across a range of applications.
The board has several output signals available, which can be used as host inputs to
monitor performance. One input allows for the remote control of Servo Enable. Two
Status LEDs are on board as a quick status check for engineers and technicians. For
your convenience, a set of mating connectors and pins for the Power, Command Input,
and Diagnostic Output connectors ship with every driver board.
This manual contains all the information necessary to install and operate the servo
driver along with a precision optical scanner. Servo drivers are typically factory tuned
with a matched galvanometer and mirror. It is not advisable to attempt to adjust the
servo driver in the field. Only factory trained service technicians should attempt to
adjust any of the potentiometers on the board. If it becomes necessary to return a servo
driver board to the factory, the matching galvanometer and mirror should be returned
along with it. Any unauthorized attempt to retune the servo by an untrained individual
could result in serious damage to the scanner, mirror and electronics.
