摘要

A method for testing of faults of a drive unit of an injection molding machine, wherein the drive unit of a hydraulically actuated moving member, for example, a piston, whose position by a distance monitoring device is monitored, and comprises a pump which the moving member is capable of hydraulic fluid through at least one valve, before and after which pressure sensors are arranged, characterized in that in the case of deviations in the position of the moving member from the controlled value of the influencing the movement of the moving member elements of the drive unit are actuated individually, in order to check its functionality, and in that the identified as defective element is reported to the control of the injection molding machine and / or on a display is made visible.
