<p>#CMT# #/CMT# The method involves detecting a stepper position (Xist) of a stepper, and specifying speed (nv) of a winding device based on the detected stepper position. Control parameters (KP, TN) are automatically determined in dependence of a diameter of the winding device during operation of a processing machine. Speed of the winding device is specified for winding or unwinding a material web e.g. paper or card board. Speed of an impact tool i.e. transport roller, is specified for transporting a material web. #CMT# : #/CMT# An independent claim is also included for a control unit for automatically determining a control parameter of a stepper position-control element in a processing machine. #CMT#USE : #/CMT# Method for automatically determining a control parameter of a stepper position-control element e.g. proportional controller, proportional derivative controller and proportional-integral-derivative controller, in a processing machine i.e. printing machine. #CMT#ADVANTAGE : #/CMT# The control parameters are automatically determined in dependence of the diameter of the winding device during operation of the processing machine, thus parameterizing stepper position control in a simple and automatic manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block diagram of a control circuit for a processing machine.
