The 9/440 Resolver--based
CNC/Drive System
The 9/440 Resolver--based CNC/Drive system is a unique machining
solution that incorporates a CNC with a digital drive as a single cohesive
unit. This system improves machine performance as well as decreasing
cost, system integration time and cabling. The 9/440 Resolver--based
CNC/Drive supports up to four closed loop axes and two closed loop
analog systems (typically spindles).
This system is designed to interface to Allen-Bradley 1326 digital servo
motors.
The following figure shows some of the key features of the
9/440 Resolver--based CNC/Drive:
