Abstract
There is provided an electronic monitoring device for indicating when the stopping time or stopping distance of a brake adapted to stop the motion of the power press drive system exceeds a preselected time or distance. In accordance with one aspect of this device, there is provided means for creating a selected number of control pulses having a time spacing between successive control pulses inversely proportional to the rotational velocity of the press shaft, a digital counter having an input for counting pulses and means for starting the counter upon creation of a stop signal for the press, means for creating counting pulses having a known time base frequency, means for directing the counting pulse to the input of the digital counter, means for creating a first signal when the digital counter has counted to a selected number, means for creating a second signal when the time spacing of successive control pulses exceeds a preselected time and indicating means actuated upon creation of the first signal before creation of the second signal.
