5.5.20 Tension control solutions
In many fields of industrial production, precise tension control is needed to maintain a constant
output tension of the drive equipment, in order to improve the quality of the products. In the
winding and unwinding of some industries such as paper processing, printing and dyeing,
packing, wire and cable manufacturing, textile, fiber, optic cable, leather, metal foil material
processing and so on, tension needs to keep constant.
The VFD controls the tension by regulating the motor output torque or speed. There are three
modes to control the tension: speed mode, open-loop torque mode and closed-loop torque
mode.
