Abstract
An electric braking device for printing material processing machines includes at least one electric drive to be braked that is supplied by a power converter in motor operation and is braked by the power converter in generator operation. A control unit switches on a redundant electric braking device in the case of a failure of the power converter by using a switch. The braking device has at least two braking stages, an additional switch for actuation in at least two stages, and at least one brake resistor. In the circuit of the redundant electric braking device, a braking current is measured and the measured value is fed to a comparator for comparing the actual braking current to a desired braking current. A printing press having the braking device is also provided.
