Embodiment Construction

[0014] figure 1 shows the essential parts of a digital controller according to one embodiment of the present invention. The CPU 11 is a processor that controls the digital controller 10 as a whole. ROM12, RAM13, nonvolatile memory 14, interfaces 15, 16, axis control circuit 17, spindle control circuit 18, PC (programmable controller) 19, and communication interface 20 are connected to CPU 11 through bus 24, such as nonvolatile memory of CMOS memory. Volatile memory 14 is battery backed up.

[0015] The ROM 12 stores software for executing a process of transferring various system programs from the nonvolatile memory 14 to the volatile memory RAM 13 when the power of the digital controller described above is turned on. The RAM 13 holds various system programs transferred from the nonvolatile memory 14 , and also stores various data input by an operator through the display / manual input unit 30 , machining programs, and the like.

[0016] Basic system programs and additional sy...

Abstract

A numerical controller designed to reduce a wait time between power turn-on and machine activation. When power to the numerical controller is turned on, programs of additional functions are each selected to be either transferred or not. The selection is made by setting each of the programs of the additional functions either to be transferred or not on a display screen or by an external input signal inputted from a machine operation panel or the like. Only the selected system programs of the additional functions are transferred from the nonvolatile memory to the volatile memory. At the time of the power turn-on of the numerical controller, only the system programs of the additional functions to be used at the moment are transferred. The data to be transferred from the nonvolatile memory to the volatile memory is thus reduced, and the transfer time is shortened. Consequently, the wait time between power turn-on and machine activation is reduced.

Description

technical field [0001] The present invention relates to a digital controller, in particular to a digital controller with a short start-up time. Background technique [0002] With the development of digital controller technology and functions, various functions have been realized. Therefore, when the power of the digital controller is turned on to start the controller, processes requiring initialization, setting, and execution of various functions are added. This prolongs the waiting time when starting the machine tool, and thus, the operating efficiency is reduced. [0003] As a method of reducing the startup time of the information processing apparatus, there is a known method in which the user sets the intended purpose and function, and selects and executes a necessary function among different functions according to the intended purpose and function when the information processing apparatus is started (See JP11-3129A). [0004] In this digital controller, in order to ac...
