Abstract
A multi-drive printed product processing device is provided that includes a processing component and a motor driving the processing component. A motor control controls the motor. An encoder measures a position of the motor and sends an encoder feedback signal indicating the position. The motor control receives the encoder feedback signal. An encoder feedback signal verification circuit verifies the integrity of the feedback signal. A printing press is also provided.
