Numerical controller with multicore processor

Abstract

A numerical controller includes a multicore processor, an integrated peripheral control LSI, a motor control section and an amplifier interface section. The multicore processor has two cores. One is assigned as a numerical control section processor core, and the other is assigned as a programmable machine controller section processor core. The motor control section is composed of a motor control section processor and a peripheral control LSI.

Description

technical field [0001] The present invention relates to numerical controllers for controlling machine tools and industrial machinery. Background technique [0002] A numerical control device for controlling a machine tool or an industrial machine includes functional blocks such as a numerical control unit, a motor control unit, and a PMC (Programmable Machine Tool Controller) unit, as disclosed in Japanese Patent Application Laid-Open No. 9-69004. connected to each other via a bus. use figure 1 A configuration example of such a conventional numerical controller will be described. [0003] figure 1 The shown numerical controller 10 has functional blocks of the numerical control unit 11 , functional blocks of the PMC unit 12 , functional blocks of the motor control unit 13 , and functional blocks of the amplifier interface unit 14 . These functional blocks are connected to each other via an internal bus 15 . [0004] Processors 20, 30, and 40 for performing respective con...

Problems solved by technology

However, as a result of connecting multiple processors to the integrated peripheral control LSI, a large number of I / O pins are required on the peripheral control LSI

If the number of I / O pins exceeds the number that can be accommodated in the envisaged package of the peripheral control LSI, it will be difficult to realize the integration of the peripheral control LSI (see figure 2 )
