Motor control characteristic evaluation device and motor control characteristic presentation method

Abstract

A motor control characteristic evaluation device includes: an evaluation index selection unit which selects any one of evaluation indexes in a motor control system control characteristics and outputs selection information indicating the selected evaluation index; a correlated data extraction unit which extracts data correlated with the selected evaluation index from the motor control system data group according to the selected information; an evaluation value calculation unit which calculates an evaluation value of the evaluation index according to the extracted data; and a display control unit which displays the calculated evaluation value on a display.

Description

technical field

[0001] The present invention relates to a device for evaluating motor control characteristics and a method for presenting motor control characteristics. It presents information on the control characteristics of a motor control system including a control object and a controller to a user for evaluating the control characteristics of a motor, wherein the control The object contains the motor and the controller controls the control object. Background technique

[0002] In such a technical field, the technique described in Patent Document 1 is known. The invention described in this Patent Document 1 has a maintenance device that manages input signals from encoders, control signals to servo motors, control signals from a higher-level control device, In the course of the control signal, the internal signal of the servo amplifier, etc. The maintenance device monitors the abnormality of the servo amplifier, outputs operating parameters to the servo amplifier, contr...

Embodiment approach 1

[0060] figure 1 It is a configuration diagram of a servo motor system including a motor control characteristic evaluation device according to Embodiment 1 of the present invention.

[0061] exist figure 1 In the servo motor system shown, the servo motor control device 51 applied to this embodiment has ROM53, RAM54, and CPU52, and controls the rotation of the motor 61. The ROM 53 is a memory that stores operating programs necessary for controlling the device. The RAM 54 is a memory for temporarily storing data and the like during control. The CPU 52 is a processor that performs logical operations.

[0062] The motor 61 drives the load mechanism 71 so that the table 74 moves via the ball screw 73 rotatably fixed on the base 72 . A rotation detector 81 is attached to the motor 61 , and the rotation detector 81 detects a rotation position, a speed, and the like, and notifies the servomotor control device 51 as detection data. The motor 61 and the rotation detector 81 are elec...

[0123] Next, Embodiment 2 of the present invention will be described using the drawings.

[0124] Figure 14 It is a processing flow chart of the motor control characteristic evaluation device 22 according to the second embodiment of the present invention.

[0125] In contrast to the first embodiment, in which necessary data is extracted from the stored input and output data, in this embodiment, only the input and output data necessary for calculation of the evaluation value is measured and stored.

[0126] Such as Figure 14 As shown, the motor control characteristic evaluation device 22 selects an evaluation index (step S23), extracts necessary data (step S24), and measures and stores input and output data (step S25).

[0127] The motor control characteristic evaluation device 22 in this embodiment can measure and store only the data necessary for calculating the evaluation value of the selected evaluation index as described above. Therefore, the amount of data stored in ...
