Laser/Scanner Control Electronics

QuantumDrive - 4000 Servo-Amplifier

• Smallest Class-1 Servo Amp Available
• +/- 15 to 28 V Power Range
• +/- 3, 5 or 10V Command
• Provides soft start/stop operation, over position, open circuit, AGC fail, and over/under voltage protections for laser systems and scanning mirrors
• High Quality Low Noise, Low Drift Components
• Self Protection Circuitry with Diagnostic Signals and LED's
• Class 1 PID Loop- with additional servo terms for extra stability and control

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.

QD-4000 servo-amplifiers, tested and tuned with a matching galvanometer and mirror to customer specifications, offer the strongest available galvo-based scanning solution in their class for a variety of applications including: Coding, Marking, Engraving, Cutting, Display, Fluorescence, Imaging, Microscopy, and many others.
