Problems solved by technology

[0012] The above-mentioned invention is based on the premise of synchronization within the same unit, and is different from the technical problem of improving the synchronization accuracy between asynchronous units using synchronization information.
In addition, in addition to the structure for inputting the speed command to the main control unit, this technology also requires a structure such as a high-level command device for inputting the position command to each unit in parallel, so the hardware structure is complicated.

Embodiment Construction

[0024] image 3 It is a hardware configuration diagram showing main parts of the numerical controller M1 and the numerical controller S1 according to the embodiment. Both the numerical control device M1 and the numerical control device S1 are industrial machines (hereinafter also simply referred to as machines. Typically, they include Figure 6 As shown in the press machine, etc.), the numerical control device M1 acts as the control object machine in the master-slave mode as the master control unit, and the numerical control device S1 acts as the control object machine in the master-slave mode as the slave unit to act.

[0025] The numerical control device M1 and the numerical control device S1 each have a CPU 11 , a ROM 12 , a RAM 13 , a nonvolatile memory 14 , a bus 10 , an axis control circuit 16 , a servo amplifier 17 , and an interface 18 . The servo motor 50 and the input / output device 60 of the main control unit are connected to the numerical controller M1. The servo...

Abstract

A numerical controller for performing axis synchronous control between a plurality of units in a master-slave mode performs speed-based synchronous control in a predetermined section and performs position-based synchronous control in another section.

Description

technical field [0001] The invention relates to a numerical control device, in particular to a numerical control device capable of synchronizing multiple units with high precision. Background technique [0002] Systems for synchronizing the positions of a plurality of industrial machines are widely used. In the inter-unit synchronization system, synchronization information (position command) is periodically transferred from the master unit to the slave units, and operations are synchronized using the transferred synchronization information. However, in a system where units are not synchronized, it is not easy to synchronize operations with high precision using synchronization information. [0003] For its reason, use figure 1 Be explained. figure 1 It is a graph showing an example of the correspondence between the transfer timing of synchronization information from the master unit (also referred to simply as the master unit) to the slave unit (also referred to simply as t...
