1. process requirement:

a. wind up and back off control function, wind up condition in normal working.

b. Require the tension rocker stable during the whole working period.

c. Winding speed required above 1200m/min(winding inverter running frequency above 60HZ)

d. Band-type brake immediately while stop.

2. Inverter function requirement:

a. terminal control , foreward running FWD(wind up),reversal running REV(back off)

b. frequency source switch in wind up and back off condition, wind up use PID control, while back off use AI1 given frequency.

c. Require immediately PID adjust when wind up, acceleration and deceleration time is

0.1S,so the inverter should equipment with brake unit.

3. Structural drawing and system control:


4. Control application and adjust explanation:

The wind up inverter as to adjust frequency during the adjustment, as the wind up rolling diameter increase, the line speed should be increased, use PI9000 as line speed constant control, the main wind up inverter PI9200 055G3,control the motor to winding, as the feedback single of the displacement sensor to adjust the speed, keep the tension rocker stable, just as a simple PID control. The winding motor was not running while back off, back off motor reverse control, the speed was given by potentiometer AI1.for avoid break the line when the back off speed was too fast, there need a top frequency, the acceleration and deceleration time need to be more.

6. The notice when adjustment:

a. The PID control direction must be negative direction.

b. The inverter stop should be choose free stop when the inverter stop the motor must be Band-type brake immediately.

c. The FWD /REV acceleratine and deceleratine time is different, it need the terminal to switch the acceleratine and deceleratine time.
