Automation equipment debugging-guanshentai automation equipment manufacturer

　　At present, the automation equipment we have come into contact with are: lithium battery, 3C, medical treatment, logistics, food, automobile, etc. There are also many brothers who are engaged in the debugging of automation equipment. The subdivisions are different, and the content, methods and steps of debugging are also different. Please bear with me if the following debugging steps do not apply to your segment and equipment.

　　Regarding the commissioning steps, our equipment is installed and powered on, and the commissioning stage begins. The commissioning of automated equipment is generally divided into the following stages:

　　1. Equipment/system inspection:

　　The inspection of the installed automation equipment or system is mainly used to check whether the equipment is installed correctly and meets the process requirements, whether the screws are all locked, whether all the modules move smoothly, and whether there is any interference in the mechanism. Also check whether the device wiring is firm and there are no errors, especially whether there are short circuits or missing connections. All checks are performed according to the electrical schematics to prevent missing items. At the same time, special attention should be paid to check whether the grounding of the system is correct.

　　In order to reduce unnecessary losses, be sure to check the voltage of the input power supply before power-on to confirm whether it is consistent with the voltage required by the schematic diagram. For expensive electrical components such as PLC and inverter, this step must be carried out carefully to avoid reverse connection of the input and output of the power supply and damage to the components.

　　2. Download (import) program:

　　PLC program, touch screen program, display text program, etc. Import the written program into the corresponding system and check the alarm of the system. The debugging work will not be very smooth, and there will always be some system alarms, usually because the internal parameters are not set or the external conditions are enough to become the conditions for the system alarm. This should be judged according to the experience of the debugger. First, check the wiring again to ensure that it is correct. If the fault alarm can not be solved, it is necessary to carry out a detailed analysis of the internal program of the PLC, etc., and analyze it step by step to ensure that it is correct.

　　3. Single point test

　　Also known as dotting or jogging. After shielding the internal program of the PLC, the debugger strictly tests the input/output of the system by forcibly setting/resetting to ensure that all the I/O points of the device function normally.

　　4. Functional testing

　　Unlock the shielding of the PLC program in turn, test the functions of the system item by item, and verify whether the logic of each automation program function module is correct by simulating the operating environment and conditions on site. Such as testing the start, stop and emergency stop conditions of the starter motor. During the debugging process, it is not only necessary to debug the functions of each part, but also to simulate the set alarms to ensure that the real alarms can be realized when the fault conditions are met.

　　5. Simulation joint debugging

　　Under the condition that the real load is not applied to the automation system, the system is jointly adjusted (for example, the liquid injection machine in the lithium battery production line is not injected with electrolyte, but water is used instead). Focus on the automatic linkage, manual function operation, alarm and emergency stop functions of the test system.

　　6. Light load joint debugging

　　Carry out low-load debugging on the production line controlled by the automation system, and some peers call this step a running machine with material to verify the working ability of the system under real conditions. From the initial slow speed, gradually accelerate to the mass production speed required by customers.

　　7. Full load debugging and acceptance

　　Make the system work under the designed full load to test the production capacity of the system. At the same time, the acceptance of the system (project) will be started, and the staff of the owner will be trained to ensure that the follow-up production personnel can operate and use the machine correctly.
