Motion Control Scheme Of Anchuan Motion Controller For Shareholder

The plywood machine is an important equipment in rubber hose industry. The quality of metal wire plywood directly affects the quality of rubber hose.yaskawa The joint stock machine is composed of motion controller, servo controller and motor, frequency converter and other detection switches.yaskawa
The schematic diagram of the system is as follows:

Difficulties in Using PLC System
(1) The winding machine is unevenly distributed and piled up at the reversing position;
(2) The spiral pattern appears at the reversing position of the winding machine, which is uneven; <3 />(3) It is impossible to perform the truncated cone ramping of the truncated cone
Difficulty Analysis
(1) The winding is not uniform at the commutation, and the accumulation occurs mainly due to the speed command processing time of the PLC. Long (about 10ms), there is no synchronization command and it can't be refreshed in real time, and the response speed is not enough;
(2)The thread appears in the reversing direction mainly because the winding method is thread winding, after the last winding Need to carry out half-turn positioning winding;
(3) The truncated cone is required to increase the line width and line thickness per turn when climbing, so the calculation should be performed after each winding, due to PLC operation time. Too long, resulting in the inability to perform high-speed climbing and winding motion controller
The algorithm of the system is as follows:

 
Solution
Our company's first generation products use Yaskawa's MP940 dedicated motion controller. The MP940 is a 1.5-axis controller. The servo controller is integrated in the MP940. It uses bidirectional RAM to communicate with the controller. There is no delay in the motion controller. Switching I/O and an analog output (controlling the frequency converter), programming the motion controller with the CP717 software

 
After Debugging, the control cabinet of the joint stock machine with good effect is as follows:

In order to reduce the cost of OEM manufacturer, (MP940 price is higher and has been discontinued at present), our company introduced the second generation products, using TRIO motion controller instead of MP940, and adopting universal servo system, which greatly Reduced the cost and achieved the same effect as the first generation products.
