ABSTRACT:
A method of determining an operating status of an adjusting drive of a printing machine having an electric motor drivable with varying direction of rotation, and a gear transmission arrangement includes determining a value of at least one of a torque produced by the electric motor and a variable dependent upon the torque, comparing the value with a corresponding value existing during an adjustment of the adjusting drive in a constant direction, and applying the value for a torque deviating by a given threshold value from the torque occurring during the adjustment of the adjusting drive in the constant direction as a criterion for an operating status deviating from the adjustment on the constant direction.
