3.2主要工作原理
逆變器部分采用多單元并聯(lián)方式，stacking, AC servo controller and AC servo motor control gantry lifting, accurate and stable, so as to ensure the stacking effect;
5. Changing orders and stacks without shutdown can be networked with the production management system to improve production efficiency.
1. Stable transportation and accurate order replacement.
2. The stacking is smooth and the stacking is changed smoothly.
3. Simple operation and convenient maintenance.
Remarks: due to different customer requirements, this scheme only takes gantry stacker as an example
The full set of CANopen bus control of u system solves the disadvantages of many wiring caused by pulse control, inaccurate positioning accuracy caused by pulse loss and poor anti-interference ability. At the same time, it also has high cost performance;
U the system is controlled by F1 series bus PLC of Buke electric, with a high degree of automation. The software adopts CoDeSys software of German 3S company, the mainstream software in Europe. Its CPU frequency is as high as 800m, and the program execution accuracy is 1ms. It can still maintain the stability of the system on the 130m production line;
U the system is equipped with two can bus interfaces, and the frequency converter is controlled separately in one way
