1．Electric control principle

This system makes centralized operation and processing with the programmable logic controller (PLC) provided by Germany Siemens and realizes the following automatic and accurate control with some special modules and components of Siemens:

1) Speed control: regulating speed by Yaskawa, it can trace the motor parameters automatically and obtain greater torque and more steady speed under the super low speed by changes of speed mould, vector control of magnetic flux, on-line auto adjustment and avoiding the effects of motor temperature. Meanwhile, the PLC adjust the host and the coordinated control of wire take-up, wire storage and wire rewinding to their own best conditions, so as to ensure the stabilization of line diameter ΦD in the Ac/Dc process of production line, improve the production efficiency and reduce the production cost.

2) Temperature control: adopting the Siemens EM231 temperature control mould and PLC automatic control, replacing normal contactor with the FOTEK solid state relay, and with the characteristics of high precision and long life.

3) Control panel: with the (10.4 color) touch screen of Siemens, operation parameters such as show temperature, set temperature and machine speed, friendly operation interfaces such as host and take-up single and coordinated control, stop selection for broken, fault display, operation record and so on, humanization design and simple, easy and safe operation.

2. Main Electric Control Box

1) 11-level PID automatic temperature control system, ammeter, voltage meter and digital meter counter.

2) Line diameter remote indicator of outer diameter testing and controlling instrument

3) Power display, power switch and emergency switch

4) Host and take-up synchronization control system

5) Single and coordinated control of system

6) Setting a certain meter and broken to stop automatically

7) Line speed meter/ meter counter of FOTEK, contactor of Taiwan Shilin, switch button ofTaiwan Tend, relay of Japanese Omron and other main electric elements imported fromJapan and Taiwan.

3. Tension control box of wire storage support

Wire storage support’s start/stop, tension adjustment and so on.

4. Electrical box of wire-rewinding machine

1) Control switch of wire rewinding machine

2) Meter counter and stop selection for a certain meter

3) Alarm for a certain meter

4) Regulation switch of wire rewinding speed

5) Emergency switch for whole line
