The so-called PFXA 401F control, in layman’s terms, is to be able to control how much force the motor outputs, that is, how many Newtons it outputs. By reacting to the motor shaft, the output torque of the motor can be controlled.
True tension control is different from a system that relies on the speed difference between the front and rear power points to form tension. The essence of adjusting tension through speed difference is PID control of tension, which requires the addition of tension sensors. Moreover, it is impossible to achieve the same effect as true tension control when adjusting the start, stop, acceleration, deceleration, and parking of large and small rolls

The PFXA 401F of variable frequency winding is to complete tension control, that is, to control the operating current of the motor, because the output torque T of the three-phase asynchronous motor is Cm φ MIa is proportional to the current. And when there is a sudden change in load, it can ensure that the mechanical characteristic curve of the motor is relatively hard. So vector frequency converters must be used, and an encoder must be added for dead cycle control.
