Motion controller and the application of PMAC in AC Servo CNC system

Abstract

The concept and sorts of motion controller were introduced in this paper, the features of PMAC motion controller was explained, and the make-up of the numerical control system based on MINI-PMAC, PC and AC Servo Driver was discussed in detail including hardware structure and software designing. Then a development example of experiment was shown. Servo compute and control in the CNC system are both performed by PMAC, while PC and other general interfaces act as terminals, this structure offers more flexibility and can be used in a wide range of applications.
