The CAN bus of the REF615E-E HBFAABAANAA4BNA11E 7700080612 also sends the roll diameter information calculated by the servo controller (2/3) to the PLC, which completes the calculation of the tension given accordingly, and then sends it back to the servo controller (2/3) via the CAN bus. The requirement of the winding part of the reel is to be tight inside and loose outside, which requires a high initial tension, and as the reel diameter gets bigger, the tension gradually gets smaller according to a certain law. The application system can fully meet these requirements, and the actual operation proves that the above winding system operates reliably, and the winding diameter from 86mm to 1200mm can be wound densely and neatly, and the winding speed can be up to 80m/min.

REF615E-E HBFAABAANAA4BNA11E 7700080612 The use of RS-232 serial communication between the central controller and the squeegee unit is slow and unreliable. As a result, some critical operations are still performed using the conventional method of direct wiring. the BUSH-7V has switched to RS-485 serial communication, which has improved reliability. In our solution, CAN bus is used to achieve serial communication between the central control IPC and the inverters of each squeegee unit, broadcasting start/stop commands and monitoring the working conditions of each squeegee unit; the squeegee units can also communicate with each other, copying the setting information and simplifying the repetitive setting of parameters of the squeegee units.

REF615E-E HBFAABAANAA4BNA11E 7700080612 Given the high reliability of CAN, all control and status signals are sent over the bus, simplifying wiring and improving real-time performance.5 Serial communication with improved reliability. In our scheme, CAN bus is used to achieve serial communication between the central control IPC and the inverters of each squeegee unit, broadcasting start-stop commands and monitoring the working conditions of each squeegee unit; the squeegee units can also communicate with each other, copying the setting information and simplifying the repetitive setting of the parameters of the squeegee unit. In view of the high reliability of CAN, all control and status signals are sent through the bus, simplifying wiring and improving real-time.
