Abstract:Through the analysis of re-winder unwind roll control theory, the control demand of unwind roll was obtained, the reason and calculation method of unwinding tension were discussed. At the same time, the DCS550’scurl macro and the meaning of its parameter group were introduced. Finally the hardware connection mode of the DC adjustable-speed device and the setting of curl parameter in the curl macro application were presented.
