Specialized specifications for tension control Tension control mode: when user select mode 0 – vector control without PG card (used simultaneously for synchronous motor and asynchronous motor), mode 1- vector control without PG card (simultaneous use of synchronous motors, mode 2 (SVPWM control, mode 3 (closed loop vector control for synchronous motors and induction motors).)
 Tension feedback speed control mode : In this mode, the rotation speed is controlled to perform tension fixation First, calculate the co-velocity frequency according to the long speed of the sheet material (or fiber) and the roll diameter. Its signal the tension of the measured tension and the preset tension put on the closed-loop control PID, and finally ordered adjust the frequency of the inverter.
 How to calculate the frequency at the same speed as follows: f = ( V * N * i) / (π * D)
Where:
      f: Output frequency of inverter
      V: material length
      N: number of poles of motor
      I: mechanical transmission ratio
      D: Coils diameter
 Speed ​​of material obtained from module speed, into the winding diameter is obtained by the value calculated from the module diameter of the plot. To ensure the synchronous frequency accuracy can reduce PID tuning, in order to increase the system stability. In other words, accuracy of long velocity measurement is important.
  Tension non-feedback speed control mode: this mode of GD35-07 is applied in the case of GD35-07 as a Master and the tension feedback signal is not required, the winding diameter is calculate. The speed in this case is constant.
  Torque control mode without tension feedback: (open-loop tension control) tension control is controlled via direct motor torque. The speed changes according to the material’s linear speed automatically. The inverter’s output torque is calculated by setting tension and winding diameter T = (F * D) / (2 * i)
 Where:
         T: torque set for inverter
         F: set tension
         D: line coil glass
         I: Gear ratio of the
 inverter mechanical can achieve stable tension control effect in the load control mode. Note that if the torque mode is used to control the tension, the moment of inertia should be considered during acceleration / deceleration.
