<p>The invention relates to a method for compensating abnormal tensile loads (SSt) in a strip (8) of an acceleration-guided coiler drive consisting of a driving motor (10, 12), a drive shaft (12, 14), and a coiler (4, 6). According to the invention, an actual acceleration (MBM) of the driving motor (10, 12) is determined from a determined actual speed (nM) of said driving motor (10, 12) and is compared with a desired acceleration (MBM) of the driving motor, said desired acceleration (MBM) being calculated from a predetermined motor-related desired acceleration (M * Bu ). A corrective variable (MKor) is determined from the difference between the actual and the desired acceleration, and said corrective variable (MKor) is superimposed on a generated desired moment (M * M ) of the motor in such a way that the determined difference between the actual and the desired acceleration becomes zero. Abnormal tensile loads are thus corrected, thereby preventing the strip from breaking.</p> |
