ABB Web TensionSystems with Tension Electronics PFEA 113

Principle of operation

The PFEA 113 tension control unit receives the feedback signal from the tension sensor, compares it with the preset tension value, calculates the deviation, processes it by means of PID and other control algorithms, and finally outputs a control signal to the actuator. The actuator adjusts the tension of the controlled object according to the control signal until the preset tension value is reached.

System components

PFEA 113 Tension Control Unit: As the core component of the system, it is responsible for receiving the signals from the tension sensor, processing them and outputting control signals to regulate the action of the actuators (e.g. motors, cylinders, etc.), thus realising precise control of the tension.

Tension sensor: Used to monitor the tension value of the controlled object in real time and transmit the signal to the PFEA 113 tension control unit.

Actuator: Adjusts the tension of the controlled object according to the output signal of the PFEA 113 tension control unit, e.g. by adjusting the speed of the motor or the pressure of the cylinder.

Profibus

• Profibus On/Off The Profibus can be enabled or disabled. 

• Profibus Address? If the Profibus is enabled, the Profibus address must be set in the range 000 - 125. 

• Profibus Measuring Range? If the Profibus is enabled, the Profibus Measuring Range and load division can be set for Roll1 and Roll2 separately.

Default Scaling

This is a similar function as in previous software versions, SW 1.0-1.7. Load Cell Combination, LoadCellComb: One roll or Two rolls For Load cell Combination One or Two rolls, default scaling is a similar function as in previous software versions, SW 1.0-1.7. The main change is for Difference signals. In SW 1.0-1.7, the difference signal has a separate scaling. In SW1.8, all signals for each measurement object have the same scaling. For difference signals, the load scaling must be adjusted in the Profibus master when replacing an old unit with an SW1.8-unit. Load Cell Combination, LoadCellComb: Segmented roll For SW1.8 Default scaling has a similar function as the 9 to 12 load cells function (connected to an analog output) in SW 1.0-1.7, with the exception for difference signals. For 3-8 load cells, the load scaling must be adjusted in the Profibus master when replacing an old unit with an SW1.8-unit.
