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.
