Because of the increasing use of smart cards, graphics have become all sorts of strange things. It is necessary to design different tool movement trajectories each time according to different graphics. After the trajectory is designed, the controller and the actuator are used to mill. A well-designed pattern requires the tool and the XY axes to run quickly and smoothly during execution.
Yaskawa motion controller advantages:
1. Installation The connection between the MP controller and the servo driver requires only one communication line to complete the servo connection and control. The installation is simple and convenient.
2. Speed ​​MP controller uses high-speed CPU, greatly reducing the command execution time. In addition, the use of MECHATROLINK-II (transmission speed 10Mbps), MECHATROLINK-III (transmission speed 100Mbps) to achieve multi-axis rapid high-speed movement, the fastest transfer cycle of 125μs.
3. The original control method of the program The tool path is planned - the track length data - converted into the number of pulses - the controller sends the pulse - the servo driver receives the pulse signal - the servo operation.
3.2 Adopt CAD import function (in R&D, test phase)
As smart cards are used more and more widely today, the types of cards are also varied, and each kind of card graphics must undergo trajectory planning and program design, which seriously increases the workload of engineers, and the scope of use of the machines is also narrow and can only be a One or several patterns operate.
For this industry situation, our current plan is: "CAD import function."
First of all, using AutoCAD to draw a plane figure - through the software we developed to convert the CAD graphics into data - use the MP controller to identify the data - control the servo motor to make the trajectory according to the graphics.
After such a good template, will greatly reduce the workload of engineers, save time, save time and effort, and increase the use of the machine to improve efficiency.
The MP motion controller is a little bit different now:
1 By setting the transmission ratio, screw pitch, and control accuracy between the motor side and the lead screw through the MP parameter, the track length data can be sent directly to the servo driver to complete the positioning, eliminating tedious calculations.
2 large-capacity MP2000 series controller user storage capacity of up to 5.5MB - 11.5MB, do not worry about programming problems after programming multiple patterns.
3 Positioning The interpolation control program is extremely simple to write, and a simple text-based programming language can be used to perform complex motion control. Supports ladder diagrams, text-based programming languages, BASIC languages, and embedded C languages ​​that can coexist with ladder diagrams and motion languages.
4 full range of debugging features. For machine debugging, you can step-by-step execution of commands or set breakpoints. The debugging operation is simple.
5 The program automatically handles the problem of speed link between each section of linear interpolation and arc interpolation so that the machine runs smoothly without additional design procedures.
6 The best mechanical performance can be achieved through simple servo debugging
