Abstract
A method for tuning operation of servo motors includes selecting a plurality of discrete positions in a guillotine blade cycle for which to determine tuning coefficients, determining tuning coefficients at the discrete positions, interpolating tuning coefficients for positions between the discrete positions, and applying the determined and the interpolated tuning coefficients to the servo motor. The servo motors may be used in connection with a guillotine cutter for separating individual sheets from a continuous web. The guillotine cutter blade may be driven by a servo motor to cyclically lower and raise to transversely cut the web transported below the cutter blade.
