可编程序卷板机毛病扫除大法

（1）接口信号查看：经过用可编程序卷板机操控器查看机床操控体系的接口信号，并与接口手册的正确信号相比照，亦可查出相应的毛病点。

（2）仪器丈量：当卷板机体系发作毛病后，选用常规卷板机电工检测仪器，东西，按体系电路图及机床电路图对毛病部分的电压，电源，脉冲信号等进行实测判别毛病地点。如电源的输入电压超限，引起电源监控可用电压表测网络电压，或用电压测试仪实时监控以扫除其它原因。如发作卷板机方位操控环毛病可用示波器。

（3）用可编程操控器进行PLC中止状况剖析：可编程序操控器发作毛病时，其中止原因以中止仓库的方法回忆。运用卷板机编程器能够在体系中止状况下，调出中止仓库和块仓库，按其所指示的原因，查明毛病地点。

Three methods of removing defects in plate bending machine

(1) interface signal view: after using the programmable bending machine operator to view the interface signal of the machine tool control system, and compared with the correct signal of the interface manual, also can find out the corresponding fault point.

(2) instrument measurement: when the bending machine system defects, the use of conventional bending machine electrical testing instruments, things, according to the system circuit diagram and machine tool circuit diagram of the fault part of the voltage, power, pulse signals, etc., to determine the location of the fault. If the input voltage of the power supply exceeds the limit, the power supply monitoring can be used to measure the network voltage by the voltage meter, or the real-time monitoring by the voltage tester can be used to eliminate other reasons. For example, the problem of azimuth control ring can be used.

(3) PLC interrupt status analysis with programmable controller: when the operator controls the attack, the reason is to stop the memory of the storage method. By using the programmer of the bending machine, the warehouse and block warehouse can be called out and the trouble place can be found out according to the reasons.
