Digital regulation device for hydraulic axle of injection molding machine, has regulator mechanism comprising digital regulator elements for processing of axle at respective sampling rates, where one rate is higher than another rate
The device (R2) has a regulator mechanism comprising a position/speed regulator (26) and a pressure regulator (32) for processing of a hydraulic axle at lower and higher sampling rates (fa1, fa2), where one sampling rate is higher than the other sampling rate. The respective regulators are realized in a software form and by a hardware circuit, which is realized by a field programmable gate array. The regulators are connected in series such that output of the position/speed regulator determines a guide parameter (24) for the pressure regulator. An independent claim is also included for a method for operating a digital regulation device.
