Abstract
Abstract In a method for measuring the rotational speed of a machine, especially a printing machine, in which an incremental-signal transmitter produces tachopulses, counting pulses are counted during a time period derived from the tachopulses. At the end of the time period, a program interruption is triggered at a computer and the counter reading is read by the computer. <IMAGE>
