Feedback type tension controller

Feedback type scheme

This type of controller directly measures the material&nbsp;tension using the tension detector, and performs&nbsp;feedback control so that the tension during unwinding and&nbsp;winding matches the set value. This method can&nbsp;accurately control tension with regard to the set value.&nbsp;When performing externally sequenced multiple-shaft&nbsp;switchover control, new reel pre-set control is performed&nbsp;based on the reel change input signal. However, pre-drive&nbsp;control shall be performed externally.

Open loop type tension controller

This type of controller detects the reel diameter using&nbsp;sensors and controls the unwinding and winding&nbsp;torque. This method can stably control tension without&nbsp;being sensitive to sudden disturbances.&nbsp;Unwinding braking torque and winding torque shall be&nbsp;controlled based on the reel diameter measured on a noncontact basis

Features

<ul><li>Highly advanced tension control</li><li>Perform feedback control or open-loop control in accordance with the connected adapter</li><li> Highly&nbsp;precise tension controls with high response and stability are achieved by&nbsp;feedforward/feedback&nbsp;complex control brought by the combination of feedback control and open-loop control.</li><li>Sophisticated tension control is achieved using the polygonal line taper function and inertia compensation gain automatic calculation based on the reel diameter data from the reel diameter calculation adapter and on the line speed/line acceleration data.</li><li>The polygonal line taper function allows the setting of up to 8 points to enable detailed taper control&nbsp;in accordance with the material and reel diameter</li></ul>

The LE-10WTA-CCL and LD-10WTB-CCL tension controllers offer various methods of tension control in combination with the tension detector input adapter and reel diameter calculation adapter connected to the main unit.
