摘要： A control system for injection molding machines comprises a memory means (16) for storing set values. Further, a signal input for the transmission of actual values to the control system is provided. A first control means (18) is used for the transmission of a control field with consideration to previous values. A second control means (20) is provided for the transmission of a correction value, in particular with consideration to a deviation of the actual value from the set value. A correlation means (22) serves to correlate the control field values with the correction value for outputting a control variable.

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.
摘要翻译：公开了一种操作包括具有驱动液压泵（2）的异步主驱动马达（10）的液压装置（1）的注射成型机的方法。注射成型机在注射成型循环中运行，其中冷却阶段和注射模制工具在冷却阶段之后打开的阶段。如果冷却阶段的持续时间高于最小持续时间，则在注塑周期开始之前确定。如果冷却阶段的持续时间高于最小持续时间，则异步主驱动电动机（10）在冷却阶段之后或者在冷却阶段开始时被关闭，并且在开模注塑模具开始之前再次接通。通过根据循环关闭主驱动电机来节省电能。用于随后的注射成型循环的注射成型材料有利地通过借助辅助异步电动机驱动的供给装置以剂量方式供给，同时主驱动马达被切断。在冷却阶段结束之前，在主驱动马达（10）再次接通之前或期间，通过将储存在液压装置（1）中的机械能转换成轴（11）的旋转能量主驱动电机（10），其节省了用于启动驱动电机的额外能量。当主驱动电机再次接通时，通过专用控制电路将启动电流限制在额定电流的两倍。
