Abstract

Amplifiers connected to a CNC are provided individually with memories that are stored with ID data for discriminating the kinds and properties thereof and ID data as maintenance management data. Likewise, motors are provided with memories stored with ID data. The management of the amplifiers and the motors is facilitated by reading these ID data from the CNC and displaying them on a display unit. Based on the ID data, moreover, adaptation or nonadaptation between the motors and the amplifiers is automatically determined by means of the CNC.

Claims

1. A management method for a servo amplifier or a servo motor connected to a control device for a manufacturing machine such as a robot, machine tool and general industrial machine, comprising:

providing a storage integral to the servo amplifier or the servo motor;

storing data in the storage for discriminating fixed properties of said servo amplifier or servo motor; and

displaying the data stored in said storage on a display unit.

2. The management method for a servo amplifier or a servo motor connected to a control device for a manufacturing machine according to claim 1, wherein said control device includes an interface through which the data read from said storage can be delivered to an external computer so that said external computer can manage a plurality of servo amplifiers or servo motors used for the control device.

3. The management method for a servo amplifier or a servo motor connected to a control device for a manufacturing machine according to claim 1, wherein said control device includes an interface connected to a public network, and transmits the data read from said storage to an external computer through the public network so that said external computer can manage the servo amplifiers or servo motors used to the control device.

4. A management method for servo amplifiers or servo motors connected to a control device for a manufacturing machine, such as a robot, machine tool and general industrial machine, comprising:

providing a storage integral to the servo amplifiers or servo motors;

storing data in the storage for discriminating fixed properties of said servo amplifiers or servo motors;

reading the data stored in said storage from said control devices; and

automatically determining whether or not the individual servo amplifiers or servo motors are adaptive to one another on the basis of the read data.

5. A management method for servo amplifiers and servo motors connected to a control device for a manufacturing machine such as a robot, machine tool and general industrial machine, comprising:

providing servo amplifiers and/or servo motors connected to said control device for any of the manufacturing machines with a storage storing data for discriminating properties of said servo amplifiers and/or servo motors; and

storing in storage sections of said control devices a standard parameter table for discriminating fixed properties of said servo amplifiers and/or servo motors,

wherein, when a model name of any one of a servo amplifier and a servo motor is inputted through said control devices, the data for discriminating properties corresponding to said model name are read from said storage sections, and also data for discriminating properties are read from said storage of the other of the servo amplifier and the servo motor, whereby it is determined whether or not the servo amplifier is adaptive to the servo motor.

6. A numerical control device in which a numerical control device body is connected with one or a plurality of servo amplifiers and servo motors controlled in operation by the numerical control device body, comprising:

said servo amplifiers and/or servo motors comprise a storage integral to said servo amplifiers and/or servo motors for storing necessary information for identifying fixed properties thereof; and

a data readout connected to the numerical control device for fetching the information stored in the storage of each said servo amplifier and/or servo motor; and

a display displaying the information read by said data readout for each servo amplifier and/or servo motor on the screen of a display unit of said numerical control device.

8. A numerical control device according to claim 6, wherein said numerical control device body includes an interface for delivering the information read by said data readout to an external computer.

9. A numerical control device according to claim 6, wherein

said numerical control device body includes an interface for delivering the information read by said data readout to a public network.

7. A numerical control device in which a numerical control device body is connected with one or a plurality of servo amplifiers and servo motors controlled in operation by the numerical control device body, comprising:

said servo amplifiers and/or servo motors comprise a storage integral to said servo amplifiers and/or servo motors stored with fixed information for the maintenance management of the servo amplifiers and/or servo motors; and

a data readout connected to the numerical control device for fetching the information stored in the storage of each said servo amplifier and/or servo motor; and

a display displaying the information read by said data readout for each servo amplifier and/or servo motor on the screen of a display unit of said numerical control device.
