IC200CMM020数字量模块
电源由于功率大(达30kW),输出电压高(150kV),工作频率较高(20kHz),而对稳定精度、纹波及电压调节率均有较高的要求。选用先进的三相全控可控整流技术、大功率高频逆变器,用新型功率器件IGBT作为功率开关。三相全控可控整流和逆变器各自采用独立的控制板,IGBT驱动采用进口厚膜驱动电路,加上输入电网滤波器和平波电抗器及电容组成的滤波电路。使电源的功率变换部分具有较好的技术先进性和良好的功率变换性。
IC200CMM020数字量模块
可编程逻辑控制器采用扫描方式工作。从实时性要求来看,处理速度应越快越好,如果信号持续时间小于扫描时间,则可编程逻辑控制器将扫描不到该信号,造成信号数据的丢失。
处理速度与用户程序的长度、CPU处理速度、软件质量等有关。可编程逻辑控制器接点的响应快、速度高,每条二进制指令执行时间约0.2~0.4Ls,因此能适应控制要求高、相应要求快的应用需要。扫描周期(处理器扫描周期)应满足:小型可编程逻辑控制器的扫描时间不大于0.5ms/K;大中型可编程逻辑控制器的扫描时间不大于0.2ms/K。
