REF615E-D HBFDACADANB1BNN1XD 7700059450 exchanges information via CAN bus with three AC servo controllers 9326 for variable tension winding control, the modules are equipped with CAN communication modules in addition to 64 digital inputs and outputs. A total of three LENZE-9300 series servo controllers (9326) are used to drive three frequency-controlled asynchronous motors (M) with resolver (R).

REF615E-D HBFDACADANB1BNN1XD 7700059450 The drag roll servo controller 9326 (1) works in the speed mode, its speed feed (1/2 end) comes from the analogue output of the line’s master PLC, and the auxiliary speed feed (3/4 end) comes from the elasticated frame signal, to keep it in sync with the production line; the reel 1 and reel 2 servo The servo controllers for reel 1 and reel 2 (2/3) operate in torque mode and have an internal reel diameter calculation function, which enables closed-loop control of the tension information sent from the PLC via the CAN bus and the actual tension information sent from the tension sensor.

REF615E-D HBFDACADANB1BNN1XD 7700059450 There is no need for a dedicated speed control for Reel 1 and Reel 2, which automatically float their linear speeds to the required value. The linear speed information for the roll diameter calculation is sent by the roll servo controller via the special speed cascade interface X9-X10, and the rotational speed information for the roll diameter calculation is determined by the resolver. Reel 1 and Reel 2 work alternately to achieve continuous winding, and a shaft change motor driven by a LENZE-8215 frequency converter performs the shaft change function (not shown in the diagram).
