Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of an integrated motor-mounted control device according to an embodiment of the present invention, FIG. 2 is an exterior view of an integrated motor-mounted control device, and FIG. 3 is an integrated motor-mounted control device It shows an example.

Referring to FIGS. 1 and 2, an integrated motor-mounted control device 1000 according to an embodiment of the present invention includes a driver 100 for driving the motor 20; A display 200 for displaying the state of the motor 20; An operation unit 300 including a button for operating the driving of the motor; And a controller 400 for controlling the driver and the display according to an input of the manipulation unit.

The operation unit may include an operation button for adjusting the rotation amount of the motor 20 and a setting button S for setting the environment of the motor.

In addition, a DC power terminal 500, a power supply device (SMPS, 600), and an input/output terminal 700 may be installed on one side of the case.

The motor 20 is a step motor, and a mechanism 30 driven by a motor may be attached to the motor 20. The device may be a device that performs a rotational motion or a linear motion.

Referring to FIG. 3, the first integrated motor-mounted control device 1100 is connected to the first device 31 to control the first device to perform linear motion, and the second integrated motor-mounted control device 1200 is It is connected to the device 32 and controls the second device 32 to perform a rotational motion.

The first integrated motor-mounted control device 1100 and the second integrated motor-mounted control device 1200 may be connected to the integrated control device 30 through a PLC cable. The integrated control device 30 may control a first motor and a second motor.

In the integrated motor-mounted control device 1000, since the display 200 and the operation unit 300 are integrally mounted with the motor, it is possible to facilitate control related to motor setting in the field.

Conventionally, since the motor must be controlled at the control center, the installation operator in the field must deliver the necessary contents to the control center manager, and the control center has to perform tasks related to motor setting, which is very cumbersome. However, in the integrated motor-mounted control device in the present invention, the operator can set the motor while manipulating the operation unit 300 while viewing information displayed on the display 200. In the present invention, the operator means a person who sets the motor in the field, and the manager means a person who remotely controls the motor.

The controller 400 controls the driver to rotate until the motor finds the origin when power is supplied to the integrated motor-mounted control device 1000. That is, the mechanism 30 moves to the origin as the motor 20 rotates.

The origin may be a point where an origin sensor signal is input or a load is applied to a rotating motor.

The origin using the origin sensor signal may be used when a rotary device is attached, and the origin using a load applied to the motor may be used when the device operates linearly.

For example, as shown in FIG. 3, an origin sensor may be attached to the appliance 30. The origin sensor 321 is attached to one side of the appliance, and a rod (not shown) is attached to the lower portion of the protrusion 322 of the rotating body. When the rod (not shown) passes through the origin sensor 321 while the rotating body rotates, the sensor detects it and transmits a detection signal to the integrated motor-mounted control device. The controller 400 of the origin control device receives this, recognizes the point where the origin sensor is detected as the origin, and stops the operation of the motor at the corresponding position.

In the case of the first mechanism 31, since it performs a linear motion, the point where the load is applied can be set as the origin without using the origin sensor. When power is applied, the first mechanism 31 moves in the direction of the arrow, and when an obstacle (motor) is encountered during movement, a load is applied and the corresponding point is recognized as an origin, and the motor stops.

After the origin is set in the same manner as described above, the motor moves to the reference point.

As the motor rotates, the device moves to a preset reference point.

The operation button may include a first operation button (A), a second operation button (B), and a third operation button (C).

When the first operation button A is turned on (pressed), it moves to the reference point. In this case, the first operation button may be preset to correspond to the reference point.

The first operation button performs functions of clockwise rotation and menu selection, the second operation button performs counterclockwise rotation and enter functions, and the third operation button is shift and exit. You can perform the (exit) function.

In the present invention, since the motor is a configuration in which the motor shaft rotates according to the control of the control device and the device moves accordingly, the expressions'movement' and'rotation' mean that the device moves or rotates according to the rotation of the motor shaft. to be.

The control of the motor is performed by the operation of the controller, and the controller may be a microprocessor including a storage unit.

While moving to the origin, the user can change the reference point.

When the setting button S is turned on, a phrase indicating fine adjustment is displayed on the display 200 and then an offset is displayed.

4 shows a case where the offset is +10 degrees and the position is 0 degrees (reference point).

In this state, when the first operation button (A) or the second operation button (B) is pressed, the rotating shaft of the motor rotates and the mechanism is moved.

In this state, when the third operation button (C) is pressed,'SET MODE' is displayed on the display and a screen for setting the reference point is displayed.

When'Point 0'is displayed as shown in FIG. 5, when the second button B is pressed and stored, the current position is stored as the reference point'Point 0'. At this time,'SET 0 Point' is briefly displayed on the display to indicate that it is the set point.

When the third operation button (C) is pressed,'SET MODE' is displayed on the display to inform the user of the setting mode. Once again, the third operation button (C) is completely released from the setting and the reference point setting is completed.

When the reference point setting is completed in the manner described above, the apparatus can be moved to a desired position by using an operation button.

When the object is a rotating body, pressing the first operation button (A) moves to the reference point, that is, the 0 degree position (first point). In addition, when the third operation button B is pressed, the motor rotates by a preset first rotation amount and moves to the second point. The second point may be a position rotated by 90 degrees based on 0 degrees.

If the first operation button A is pressed while the third operation button C is pressed, it can move to the third point while rotating by the second rotation amount. The second rotation amount may be set to be twice the first rotation amount. When the second point is a 90 degree rotation position, the third point may be a 180 degree rotation position. In addition, if the second operation button B is pressed while the third operation button C is pressed, it can be rotated by the third rotation amount and moved to the fourth point. The third rotation amount may be set to be three times the first rotation amount. When the second point is a 90 degree rotation position, the fourth point may be a 270 degree rotation position.

And when you want to fine-tune, you can fine-tune after pressing the setting button (S).

When the setting button (S) is pressed once,'SET MODE' is displayed on the display, and when the setting button is pressed once more,'jog MODE' indicating fine adjustment is displayed, and then information about the offset and the current position is displayed.

5 shows that the position offset by +10 degrees from the origin is 0 degrees, and the current position is 180 degrees.

In this state, if the first operation button or the second operation button is pressed, the desired angle can be set in a clockwise or counterclockwise direction.

After adjusting the angle, press the 3rd operation button (C) to display'SET MODE', press the set button (S) to display'SET 0~3' on the display, and then display it so that the user can set the point. A phrase indicating the point is displayed.

The dip switch 800 includes a reduction ratio adjustment switch, an origin direction adjustment switch, and an internal/external origin reference selection switch.

The reduction ratio adjustment switch may select a rotation speed of the motor and a moving distance of the device.

Depending on the structure of the device, the movement distance of the device may vary during one rotation of the motor.

For example, in the case of a linear moving mechanism, the moving distance may vary depending on the width of the screw line. 9 illustrates the interior of the linear movement mechanism, and the movement distance per rotation of the motor may vary according to the width of the screw line 311.

By setting the reduction ratio adjustment switch, you can select the moving distance suitable for the equipment. For example, you can select a reduction ratio such as 2mm, 5mm, 10mm, and 20mm.

The origin direction adjustment switch sets the direction of the origin in the linear moving mechanism.

Referring to FIG. 3, when power is applied, the device 31 moves in the direction of the arrow, and when an obstacle (motor) is encountered during movement, a load is applied and the corresponding point is recognized as an origin, and the motor stops. At this time, when power is applied through the origin direction adjustment switch, the instrument 31 may be set to move in the direction opposite to the arrow.
