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, 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 inverter 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.
