学习方法上，如果能找到一个肯用实际项目带你的师傅是的，因为市面上关于PLC的教材基本上都是只教基本使用，完全没有涉及实际项目案例的。如果有机会（这个可能性很小）阅读一些的程序，对自己编程习惯的提高和编程理念的提升都是很有帮助的。如果没有，那么就需要尽可能从教材中有限的案例比如跑马灯、红绿灯、流水线这些实验性质的案例中得到实践，自己动手接接线、写程序和调试，能自力更生把这些功能调试出来，再结合一些传感器，实现模拟量输入输出的功能，基本上基础就算打好了。
欢迎您来电洽谈。阻燃性能在规定试验条件下，试样被燃烧，在撤去试验火源后，火焰的蔓延仅在限定范围内，残焰或残灼在限定时间内能自行熄灭的特性。额定电压额定电压是电缆设计和电性能试验用的基准电压。额定电压用U0、U表示，单位为V。

HJVV, HJVVP, HPVV communication cable: mainly used for transmitting audio, 150kHZ and below analog signals 2048kbit/s and below digital signals. Under certain conditions, it can also be used to transmit digital signals over 2048kbit/s. Used for short distance signal transmission. WeChat sales department is newly added in our factory. WeChat ID: QQ is not convenient for WeChat contact! HJVV, HJVVP, HPVV communication cable is introduced: used for distribution frame or switch to switch internal connection between the machine at all levels (including rural telephone bureau), such as the beginning of the line and terminal for connection to local telephone cable to the junction box or distribution frame, inner conductor wire diameter (mm) : 0.40, 0.50, 0.60, 0.70, 0.80, 0.90, logarithmic (on) : 5-1000 HPVV low-frequency communication wiring cable wiring cable HPVV ZR - HPVV broadband/product use: It is applicable to the transmission system from the remote optical network unit to the user and the subsystem of the transmission between buildings in the building wiring system. The highest transmission fre are 30MHz and 100MHz respectively.
：为了使电机的旋转速度减半，把变频器的输出频率从50Hz改变到25Hz，这时变频器的输出电压就需要从400V改变到约200V2.当电机的旋转速度（频率）改变时，其输出转矩会怎样？变频器驱动时的起动转矩和大转矩要小于直接用工频电源驱动。电机在工频电源供电时起动和加速冲击很大，而当使用变频器供电时，这些冲击就要弱一些。工频直接起动会产生一个大的起动起动电流。而当使用变频器时，变频器的输出电压和频率是逐渐加到电机上的，所以电机起动电流和冲击要小些。
