The task of the program is to complete the control, but the program that can complete the control task is not necessarily the best program. Therefore, in the programming stage, in addition to making the program logic work, we must try to make the program concise, use the most concise statement, choose a reasonable control order, and make the program the best. The problems in installation and online debugging, when installing the connection and installation wiring, pay attention to the reasonable layout, the coordination of the shield grounding and the original circuit, and the installation connection is also the re-checking project of the input output point, and the connection can be confirmed only after the connection is correct. debugging. Commissioning Before commissioning, you must first check the protection circuit of the machine operation panel and the emergency stop switch, limit switch, motor overheat, overcurrent, etc. on the bed to confirm the status is correct before commissioning.
The general debugging procedure is to perform the action debugging one by one according to the independent parts of the machine, first manual and then automatically. Some unadjusted condition signals or key signals can be artificially used by the PC to meet operating conditions. After all the manual actions have been adjusted, check the conditions of the automatic operation, and then start adding the necessary conditions for automatic operation debugging. In the commissioning phase, in order to verify the PC's control of the machine tool protection, some fault signals need to be artificially manufactured. In addition to considering the safety factors during the test, it is important to reflect the actual faults of the machine tool and the actual state of the alarm. In order to truly protect the machine in daily operation. In short, in the commissioning, we should make full use of various testing methods to continuously find out the problems and solve them to achieve the best running results. (Finish)
