Splitter manufacturer introduces the control principle

The slabbing machine is to scuttle the strip into a number of required standard strip base welded by section steel and steel plate, qualitative treatment.

Constant tension control principle

The essence of constant tension control in the process of winding and unwinding is to know the change of winding diameter in the operation of the load. Because of the change of winding diameter, in order to maintain the operation of the load, the output torque of the machine needs to change with the change of winding diameter. As for V series inverter, because it can do torque control, it can complete the control of winding constant tension. V series inverter provides three analog input ports, AUI, AVI, ACI. The three analog inputs can be defined as a variety of functions, so one can be selected as a torque given and the other as a speed limit. 0~ 10V corresponds to 0~ motor extra torque output by the frequency converter, so that the control of constant tension can be completed by adjusting the voltage of 0~ 10V. And Du Yu stripe machine, the part of the accounting coil diameter is calculated through the tension controller, of course, with PLC architecture to achieve is no problem. That is to say, the tension can be set in human-machine or text, and the winding diameter can be calculated by PLC, T=F*D/2, so the torque size of the motor output can be calculated. The torque given end of the V series converter can be obtained through the analog output.
