The QD-4000 is the smallest Class-1 servo-amplifier available on the optical scanner market. It features a new dual output power amplifiers with improved performance, low noise components that maximize signal-to-noise ratio for better accuracy, low drift components that reduce the effects of temperature variation, and a self resetting fuse to minimize service calls. QD-4000 servo architecture includes Class-1 servo control with Position, Integration, and Differentiation (PID) terms, plus additional servo terms for extra stability and control. A notch filter is selected and tuned for each unique mirror-galvo combination to maximize system bandwidth. The result is faster, more accurate scanning.
QD-4000 circuits provide soft start/stop operation, over position, open circuit, AGC fail, and over/under voltage protections for laser systems and scanning mirrors. On-board status LEDs provide service technicians with servo status and fault indication. The QD-4000 can be configured to accept several input command voltages (+/- 3, 5, or 10 Volts), and accepts input power ranging from +/- 15 to +/- 24 Volts DC.
