Abstract
A method of controlling a web in, for example, a web cutter that minimizes the destructive forces that are experienced by the web. The method includes providing a motor system for driving a web handling mechanism structured to move the web, wherein the motor system includes a motor and a motor control subsystem having a digital filter (such as a PID controller or some other suitable closed loop controller), detuning the digital filter, and using the motor system having the detuned digital filter to drive the web handling mechanism.
