    摘要： A control system for injection molding machines comprises a central control unit (26) for executing cyclical machine program sequences. Further, a visualization means (24, 25) is connected with the central control unit (26). The central control unit (26) has connected therewith, via an input/output means (16), an injection molding machine (18). According to the invention, an additional control unit (28) for cycle-independent processing of time-critical control steps is arranged independently of the central control unit (26) and is adapted for reducing the error-proneness. The additional control unit (28) is in particular an FPGA control unit.

    摘要： A method is disclosed of operating an injection molding machine including a hydraulic device (1) which has an asynchronous main drive motor (10) driving a hydraulic pump (2). The injection molding machine is operated in an injection molding cycle with a cooling phase and a phase in which an injection molding tool is opened following the cooling phase. It is determined before commencement of the injection molding cycle if the duration of the cooling phase is above a minimum duration. If the duration of the cooling phase is above the minimum duration the asynchronous main drive motor (10) is switched off after or at commencement of the cooling phase and is switched on again before commencement of the phase in which the injection molding tool is opened. Electrical energy is saved by switching off the main drive motor in dependence on the cycle. The injection molding material for the subsequent injection molding cycle is advantageously supplied in a dosed manner with the aid of a supply device driven by means of an auxiliary asynchronous motor whilst the main drive motor is switched off. Shortly before or during the switching on again of the main drive motor (10) before the end of the cooling phase, the latter is started by converting mechanical energy stored in the hydraulic device (1) into rotational energy of the shaft (11) of the main drive motor (10), which saves additional energy for starting the drive motor. When the main drive motor is switched on again, the starting current is limited to twice the nominal current by means of a special control circuit.
