设计变频同步控制电路，实时检测注塑机的流量、压力以及工艺流程信号，在注塑机各加工工序切换点，超前动态调整变频器输出频率．从而控制变频器动态响应与注塑机工序动作相匹配．解决了工序切换产生的瞬间大电流冲击对变频器的硬件损伤．提高了注塑机的生产质量和效率。%Through design of frequency synchronization control circuit, real-time detection of flow, pressure, process sig- nals and process switching point of the injection molding machine and advanced dynamic adjusting the frequency of inverter, the dynamic response and the process of injection molding machine are matched. The inverter hardware damage caused by momentary high current shocks generated by the process to switch is avoided. The production quality and efficiency of the in- jection molding machine are improved.
