AccuDrive AC Servo Drive System

AC Servo Drive System Power and Performance . . .

The AccuDrive AC250 thru AC1000S Drive systems are recognized for their dependability on large and small cutting machine applications. These high performance AC Servo Drive systems are renowned for their rugged reliability, while delivering smooth and accurate motion control. Built with the international standard +/- 10 volt analog speed signal input, and or Step-and-Direction inputs. These systems are fully compatible with all major tracing & CNC controls. Utilizing advanced digital technology, these drive systems deliver high performance motion control over a wide dynamic range. The amplifier circuitry is enclosed in a rugged steel enclosure with a hinged lid for serviceability. The Modular design allows easy setup and diagnostics with LED’s to display condition of module. The drive units are equally rugged with a AC servo motor direct coupled to a precision planetary gear unit to provide smooth motion over a wide speed range. Various styles are available to meet the requirements of most machines. Include integrally mounted encoders to support CNC applications and three channel applications. In addition to the standard 2 channel systems, all are available in truly synchronized 3 channel configurations, for use on bridge-type machines. Position synchronization is achieved through a unique balanced digital synchronization circuit that uses the encoders for true position feedback. This system is self aligning immediately on start-up and holds this alignment over the full range of speeds. Should a position error be detected, the circuit applies correcting signals to both drives simultaneously.
