Patent ID: 7298111

Claim:
A method for controlling a production unit of a production installation for the production and/or packaging of cigarettes or other articles for smoking with at least one master drive ( 11 ), and at least one dependent drive ( 20 - 22 ) whose movement depends directly or indirectly on the movement of a master shaft of the master drive ( 11 ), characterized in that the dependent drive ( 20 - 22 ) is in each case assigned a servo actuator ( 23 - 25 ), in that the servo actuator ( 23 - 25 ) determines, from an input signal, a desired value ( 29 ) for the dependent drive ( 20 - 22 ) and conveys this desired value ( 29 ) to the dependent drive ( 20 - 22 ), in that, when determining the desired value ( 29 ), account is taken of a limit value ( 33 ) stored in the servo actuator ( 23 - 25 ), and in that this limit value or, if appropriate, a corresponding limit value that is taken into account for the determination of a desired value for the master drive, is reduced in the event of access being made into the production installation when a protective arrangement of the production unit is opened.
