Abstract: A method for checking the driving and control system of a hydraulic punch press is provided which comprises the steps of delivering a stop order signal to the driving device, sensing the position of the sliding punch member along its stroke and comparing the time or the distance required by the punch member to come practically to a stop, with preset reference values, and producing a fault signal when the time or distance exceeds the preset reference values.
