Abstract
A load monitoring system for a press comprises a slide-position counting circuit, A/D converter, random access memory and display. The load monitoring system receives a load value applied to the press and a slide position value from a load detector and a slide position detector mounted on the press. The load value is converted into a digital value through the A/D converter, and undergoes sampling according to the slide position. The sampled digital load values are sequentially stored in the random access memory and after the measurement of the load, the stored values are sequentially displayed together with the corresponding slide positions. The load monitoring further comprises a calibration circuit for automatically carrying out calibration as well as slide position setters for measurement start, measurement end and display. By these position setters, slide positions at which load measurement starts and ends, and corresponding to which the measured and stored load value is displayed can be set manually.
