Aerotech's new NServo digital controller provides a low-cost path to
upgrading limited-function analogue servo systems. The controller
provides a convenient interconnection between existing analogue servo
drives and Aerotech's Firewire based A3200 Digital Automation platform, a
high performance, PC based machine control system that is capable of
controlling up to 32 axes of synchronised complex motion with a 20kHz
servo update rate.
