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 through the output torque or speed of the motor. There are three
kinds of control modes: tension speed control mode, open loop tension torque control mode
and close-loop tension torque control mode.
