Title:
CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/074518
Kind Code:
A1
Abstract:
Disclosed is a control system for managing/acquiring load torque information of a drive shaft that is in a state of being associated with an execution block of a program executed by a controller, and associating the information with display by the program and displaying thereof, in a control system comprising a control device and an information display device. For such uses as machine tools or transport equipment, there has been a demand to understand what portion of a program was operating when a heavy load was incurred. In addition, in the maintenance phase as well, for changes caused by aging of a machine that is in operation or such cases as occurrences of anomalies, there has been a demand not only to understand an anomalous situation, but also what part of the program in which the situation had occurred, and what kind of behavior was being shown. However, there has been no such function in particular. The disclosed control system has been created so as to acquire/manage load torque information of a drive shaft in relation to a currently executed block of a program being run by a controller, in addition to setting a given constraint torque and, in relation to a spot that has exceeded a value that has been set, modifying a state display of the program.
