2. The power supply for the line is three-phase five-wire AC power supply, which provides power for PLC, MCC and rectifier unit respectively. The drive control adopts the common DC bus mode to concentrate the power supply, solve the problem of regenerative power generation and improve the utilization rate of power recovery to achieve the purpose of power saving.
3. The CPU adopts Siemens new generation – simatics7-1500 series CPU, which has the advantages of full digital, free configuration, real-time multi-task processing, template-control system and rack installation, providing necessary conditions for stable operation of the equipment.
4. The remote I/O control adopts PROFINET communication bus control, which has the advantages of fast speed, high reliability, strong expansion ability, less wiring and fast construction.
5. HMI screen provides a fully controlled human-machine interface, whose main functions include: raw data input, process parameter input, actual data display, curve display, drive device control, alarm information display, emergency stop signal input display, etc.
6. The line has automatic unwinding/rewinding control, automatic servo-diameter calculation, automatic constant tension control, automatic tension slope control. Through a number of algorithms to reduce human intervention, reduce the burden of operators.
7. Siemens vector control and inverters will be preferred for the AC speed regulation system, according to user needs to change the configuration or brand.
