PLC Interruption Status Analysis of Three roll Plate Rolling Machine with Programmable Controller
When a malfunction occurs in the three roll bending machine system, conventional electrical testing instruments and tools are used to measure and identify the location of the malfunction based on the system circuit diagram and machine tool circuit diagram, including voltage, power supply, pulse signals, etc. If the input voltage of the power supply exceeds the limit, the power monitoring can use a voltmeter to measure the network voltage, or use a voltage tester to monitor in real time to eliminate other reasons.
1： If there is a problem with the orientation control ring of the upper roll plate rolling machine, you can use an oscilloscope to check the signal status of the measurement circuit, or use a three roll plate rolling machine oscilloscope to observe whether the signal output is missing phase and whether there is interference.
For example, in the process of cleaning up problems, the system alarms, and there is a hardware problem with the orientation ring of the three roll plate rolling machine. When using the oscilloscope of the plate rolling machine to check, it is found that there is a disturbance signal. The circuit top is filtered out by connecting a capacitor to make the three roll plate rolling machine system work normally. If the bending machine system cannot return to the reference point, a three roll bending machine oscilloscope can be used to check if there is a zero sign pulse. If not, it may be considered that the measurement system is damaged.
2、 To view the signal of Tuoyan
By using a programmable plate rolling machine controller to view the interface signals of the machine tool control system and comparing them with the correct signals in the interface manual, the corresponding problem points can also be identified.
3、 Analysis of PLC Abort State Using Programmable Logic Controller
When a programmable controller malfunctions, the cause is recalled by suspending the repository. By using the rolling machine programmer, it is possible to call up the suspension warehouse and block warehouse in the system suspension state, and identify the location of the problem according to the reasons indicated by them. This is a commonly used, useful, and fast method for repairing programmable controllers.
