Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to miniaturization of a motor control device having a servo driver and a servo controller.

[0002]

2. Description of the Related Art In recent years, industrial equipment using a plurality of servo motors has been increasing. Independent servo drivers for controlling servo motors have different outputs of the servo motors to be driven and the number of axes of the servo motors to be controlled. It has the advantage of being able to flexibly respond to industrial equipment.

[0003] With the miniaturization of industrial equipment, demands for miniaturization of servo motors and servo drivers have been increasing.

[0004] A conventional motor control device comprises a plurality of servo motors, a plurality of independent servo drivers, and a servo controller (NC board). Between them, a plurality of servo drivers and one servo controller are wired and connected via cables, respectively, and communicate with each other to control a plurality of (multi-axis) servo drivers by the servo controller.

[0005]

In the conventional motor control device, since a plurality of servo drivers and one servo controller are separately mounted and wired, it is difficult to reduce the size of industrial equipment. You need cables of different lengths to connect two servo controllers,
In addition, the wiring of the cables is complicated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and provides a motor control device which realizes downsizing of a motor control device, and which can downsize industrial equipment and rationalize wiring work. With the goal.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention comprises a housing for accommodating and fixing a plurality of servo drivers and one servo controller. , Or on the bottom surface in multiple stages.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to solve the above-mentioned problems, the present invention comprises a plurality of servo drivers for respectively driving a plurality of servo motors, a servo controller for controlling the servo driver, and a servo driver and a servo controller. A motor control device comprising: a housing that is stored and fixed; and wherein the servo driver is mounted on a side surface and / or a bottom surface of the housing in a plurality of stages.

As described above, since the housing for accommodating and fixing the plurality of servo drivers and the servo controller for controlling the servo drivers is provided, it is possible to simplify the installation and wiring to the device body.

Further, when a plurality of servo drivers are mounted on the housing, the servo drivers are mounted on the side surface and / or the bottom surface in a plurality of stages, so that the space of the housing can be effectively utilized and the motor control device can be downsized.

[0011] Furthermore, the space for mounting on the equipment body can be reduced by downsizing the motor control device, and the equipment body can be downsized.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, a plurality of independent thin servo drivers 1, 2, 3, and 4 are fixed to the left and right side surfaces of a metal housing 6 by two screws in two steps. . The servo controller 5 is mounted and fixed with screws in two steps in the rear space together with the power supply board. The plurality of cables 8 connect the servo drivers 1, 2, 3, 4 and the servo controller 5.
A power switch 9 and an emergency stop switch 10 of the motor control device are arranged. On the back, four sets of a power supply line 11, a connector 12 for connecting a servo motor motor line and a servo driver, and a connector 13 for connecting a servo motor encoder line and a servo driver are arranged, respectively, to constitute a motor control device. ing.

As described above, since the thin servo drivers are mounted on the left and right side surfaces of the housing, the motor control device can be reduced in size and thickness.

FIG. 2 shows another embodiment in which four short and wide servo drivers are mounted and fixed to the bottom of the housing (in four stages), and the other structure is almost the same as that of FIG. Yes, omitted.

Although not shown in the figure, as another mounting example in which there are four servo drivers, two servo drivers are mounted on one side in two stages and two are mounted on the bottom surface (two stages). Good. If there are two servo drivers, they may be mounted and fixed in two steps on either the bottom surface or the side surface of the housing. Further, in the case of three units, it may be attached and fixed to the bottom surface of the housing. Similarly, in the case of five or more units, a plurality of units may be attached and fixed to the side surface and / or the bottom surface in a plurality of stages.

As described above, a plurality of servo drivers are formed according to the shape of the servo driver, and the side of one housing and
Alternatively, the motor control device can be reduced in size by effectively utilizing the space of the housing by attaching and fixing the motor control device in a plurality of stages on the bottom surface. Furthermore, since a plurality of servo drivers and one servo controller are housed and connected in one housing, the work of attaching to the device body and wiring work can be rationalized.

[0018]

As is apparent from the above embodiment, according to the present invention, a plurality of servo drivers and a servo controller for controlling the servo drivers are provided on the housing of the motor control device on the side and / or the bottom. The motor control device can be reduced in size because it is fixed to the motor. At the same time, the size of the device body to which the motor control device is mounted can be reduced, and the mounting and wiring work can be rationalized.
