Embodiment 1

[0058] Aiming at the problems of complex wiring, poor reliability, and high cost of use and maintenance in the gantry control implementation, this embodiment provides a new motor control system for realizing synchronous operation control of at least two motors. For ease of understanding, this embodiment will be described below by taking a motor control system including two motors as an example. However, it should be understood that the motor control system in this embodiment is not limited to controlling the synchronous operation of two motors, and the control of synchronous operation of three or more motors can be deduced by analogy, which will not be repeated here.

[0059] For the motor control system provided in this embodiment, please refer to figure 2 As shown, it includes a control device 1, a first motor driver 2, a first motor 4, a second motor driver 3 and a second motor 5; wherein the first motor driver 2 communicates with the control device 1, and the first motor ...

Embodiment 2

[0074] In order to facilitate understanding, the present embodiment below illustrates the structure of the control device on the basis of the foregoing embodiments.

[0075] See image 3 As shown, the control device 1 provided in this embodiment includes a communication module 11 and a controller 12; the communication module 11 is used to receive the first position information and the second position information sent by the first motor driver 2; the first position information is the first The position information of the first motor 4 driven and controlled by the motor driver 2, the second position information is the position information of the second motor 5 driven and controlled by the second motor driver 3, and the first motor driver 2 receives the information sent by the second motor driver 3 through the communication bus. The second position information; the controller 12 is used to obtain the position difference according to the first position information and the second p...

Embodiment 3

[0088] In order to facilitate understanding, this embodiment applies the following on the basis of the above embodiments figure 2 The motor control system shown and the image 3 The control device shown and Figure 4-Figure 5 The motor driver shown is an example and one wiring to a motor control system is an example. See Image 6 As shown, the pulse output terminal of the control device 1 is connected to the pulse input terminals of the first motor driver 2 and the second motor driver 3, and the first motor driver 2 and the second motor driver 3 are connected through the RS485 communication bus. The motor driver 3 sends the real-time position information of the second motor 5 obtained by it to the first motor driver 2 through the RS485 communication interface, and the second motor driver 3 sends the second origin signal triggered by the second motor 5 when it reaches the second origin. Send it to the first motor driver 2 through the RS485 communication bus. When the first...

Abstract

The invention discloses a synchronous control method and control equipment for a gantry and a motor control system. A first motor driver and a second motor driver are connected by a communication bus,the first motor driver acquires first position information of a first motor driven and controlled by the first motor driver, the second motor driver acquires second position information of a second motor driven and controlled by the second motor driver and sends the second position information to the first motor driver through the communication bus, the first motor driver sends the first and second position information to the control equipment, and the control equipment carries out compensation control of a gantry position according to positions of the first and second position information. Compared with an existing gantry control mode, capacity of resisting disturbance is higher by interacting the position information through the communication bus, and wiring between the second motor driver and the control equipment can be simplified, so that the complex degree of wiring can be reduced to a great extent, the reliability of the system is improved and the using and maintenance costs ofthe system are lowered.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a gantry synchronous control method, control equipment and a motor control system. Background technique [0002] The motor driver is a product widely used in industrial control and automated production, such as 3C automation, single-axis manipulator, logistics and other automated control industries. In some application scenarios, including but not limited to large-scale CNC planers, laser welding equipment, glass processing and other scenarios, due to the large format involved and the requirement of fast processing speed; if the equipment in these application scenarios adopts a single Axis transmission cannot meet the requirements of fast processing; therefore, dual Y-axes are generally used for this kind of scene. If the dual Y axes are not synchronized, it will cause dragging between the dual motor shafts, causing damage to the mechanical structure, and at the same time, it will i...
