Abstract
The invention relates to a control device for controlling a multi-shaft servo motor through a PLC, in particular to a device for controlling multiple servo motors with a PLC. The device comprises the PLC and the servo motors, and is characterized in that switches are arranged between the PLC and the servo motors; and a pulse input end of each servo motor is connected with one pulse transmitting end of the PLC through a switch. The control device is low in the production cost.
Description
Technical field
The present invention relates to a kind of control device.Specifically, be to adopt Programmable Logic Controller to come the device that a plurality of servomotors are controlled.
Background technology
Know all that in servomotor production and application the control of servomotor need be sent pulse command by Programmable Logic Controller.Because it is less that mouth is sent in the pulse of Programmable Logic Controller, makes that the expansion pulse mouth of Programmable Logic Controller is limited.Therefore, the method for controlling multi-axis servo motor at present is to adopt communication bus, namely between Programmable Logic Controller and multi-axis servo motor communication bus is set, and utilizes communication bus that Programmable Logic Controller is linked to each other with servomotor respectively.The advantage of this method is that a Programmable Logic Controller can be controlled the above big system of tens servomotors.But for a system that only needs several or ten left and right sides servomotors of control, because communication bus price comparison costliness, still adopt communication bus to realize being connected between Programmable Logic Controller and servomotor, some waste just seems.Therefore, adopt communication bus to realize the control device that is connected between Programmable Logic Controller and servomotor, production cost is higher.
Summary of the invention
The problem to be solved in the present invention provides a kind of control device of controlling multi-axis servo motor with Programmable Logic Controller.This control device, production cost is low.
For overcoming the above problems, take following technical scheme:
The control device of controlling multi-axis servo motor with Programmable Logic Controller of the present invention comprises Programmable Logic Controller and servomotor, be characterized between Programmable Logic Controller and servomotor switch being arranged, the pulse input end of each servomotor links to each other with a pulse transmitting terminal of Programmable Logic Controller by a described switch respectively.
Described switch is the push-button switch with auto-lock function.
Take such scheme, have the following advantages:
By such scheme as can be seen, owing to be provided with switch between Programmable Logic Controller and servomotor, the pulse input end of each servomotor links to each other with a pulse transmitting terminal of Programmable Logic Controller by a described switch respectively.Adopt switch to realize being connected between Programmable Logic Controller and each servomotor.Switch wherein is the push-button switch with auto-lock function, and price comparison is cheap, compares with the communication bus in the background technology, can reduce production costs greatly.
Description of drawings
Fig. 1 is the control device schematic diagram of controlling multi-axis servo motor with Programmable Logic Controller of the present invention.
Embodiment
As shown in Figure 1, the control device of controlling multi-axis servo motor with Programmable Logic Controller of the present invention comprises a Programmable Logic Controller 3 and four servomotors 1, Programmable Logic Controller 3 and four 1 of servomotors are provided with four switches 2, and the pulse input end of each servomotor 1 links to each other with a pulse transmitting terminal of Programmable Logic Controller 3 by a described switch 2 respectively.Described switch 2 is the push-button switches with auto-lock function.The push-button switch that employing has an auto-lock function is realized being connected of Programmable Logic Controller 3 and 1 of each servomotor.And the push-button switch price comparison with auto-lock function is cheap, thereby greatly reduces production cost of the present invention.
Claims (2)
1. control the control device of multi-axis servo motor with Programmable Logic Controller, comprise Programmable Logic Controller (3) and servomotor (1), it is characterized in that between Programmable Logic Controller (3) and servomotor (1) switch (2) being arranged, the pulse input end of each servomotor (1) links to each other with a pulse transmitting terminal of Programmable Logic Controller (3) by a described switch (2) respectively.
