AC200-T special frequency converter for tension control keeps the tension constant by controlling the output torque and automatically calculating the roll diameter. No need to install a tension sensor, no need for external feedback signal of current position or current tension. In most applications, it is not even necessary to install a speed feedback encoder to accurately provide constant tension and ensure that the thickness or thickness of the processed material is uniform.
The V in the upper head represents the linear velocity of the traction, W represents the angular velocity of the winding reel, R represents the winding radius, and D represents the winding diameter.
AC200T tension control special frequency converter can obtain accurate winding diameter through the linear speed of the previous stage, its own angular speed, and the mechanical speed ratio.
According to the thickness of the material, the number of rotations of the installation reel is accumulated to obtain the material reel diameter. AC200T tension control special frequency converter accumulates the number of turns of the reel through the encoder, to obtain the diameter of the winding, without adding external proximity switches and several turns of devices.
Speed rigidity: Sudden 100% load and sudden unload at 40Hz, the recovery time is within 10ms.
Torque response: The load is not mechanically locked. The AC200T given torque is suddenly increased from 0% to 100% and suddenly reduced from 100% to 0%, and the torque response time is within 10ms.
Linear speed method application: the front-end machinery provides material traction to determine the material linear speed, and the material tension is determined by AC200T winding. The coil diameter can be calculated by the given linear speed of the traction.
Thickness method application: The front end machine does not provide a traction mechanism to determine the line speed, the material line speed is directly determined by the front motor, and the material tension is determined by the AC200T winding. The winding diameter of this scheme can be calculated by the lap counting pulse provided by the encoder, or an external lap counting device can be added.
Applications:Industrial production requires strip or wire to maintain constant tension.
