PROCEDURE FOR DETERMINING THE OPERATING STATUS OF AN ACTUATING DRIVE OF A PRINTING MACHINE AND DEVICE FOR IMPLEMENTING THE PROCEDURE

摘要

The present invention relates to various actuating drive mechanisms of a rotary printing press which use an electric motor to cause rotation of a shaft - the torque or torque dependant variable of the motor is measured and compared with a predetermined standard. A certain threshold deviation from the standard is then used as the criteron for correction. The standard is the torque or torque dependant variable which occurs when the motor is driven in a constant direction during the adjustment of the actuating drive. This type of control allows play in the gears or idle movement of the motor to be suitably compensated for.
