8-4-3 8 Axes Positioning Program Example
One VS series transistor or line driver Main Unit can support 4 axes position control. If the control is required more than
4 axes, one unit is not enough. However, we can use the character of the CPU LINK communication to immediately
transfer data to other PLCs. At the following example, that links two VS series PLCs to perform an 8 axes positioning.
In the same way, to control more axes are available.
The master station #0 is the main PLC to handle the communication procedure and make the positioning command,
the Station No. 1 become the real output PLC to control #5~#8 axes.
There are 3 sections to explame the control system.
Section 1: To plan the components which will be used for the data transfer between PLCs.
At the project of the master Station No. 0 to establish the CPU LINK communication table. The table is to
designate components to send the data from Station No. 0 to 1 and some are about to send data from No. 1
to 0. This example uses the D100~D114 to send the data from Station No. 0 to 1 for the #5 axis, and the
D115~D119 to send the feedback data from Station No. 1 to 0. The list below shows the related
components will be used by the #5~#8 axes.
The conguration for #5~#8 axes:
