Since transformers and motors are commonly used in factories, the interference pulses they produce are also the most common, and special attention should be paid to them. The inspection also requires the use of a power line tester or an oscilloscope with storage function.http://www.berylliumcopperalloys.com
From the analysis of the fault phenomenon, due to the high frequency of this interference pulse (generally up to 1000hz), it will not cause the power board to monitor the response, so there is usually no feature of the power board to stop working. Interference pulses will be serialized into the bus through the power supply line, causing timing errors and causing the digital controller or program controller to stop running. The detailed characteristics of the fault phenomenon vary with the amplitude and frequency of the interference pulse.https://sandcasting.top
① When the interference pulse amplitude is not high enough, it may have no effect on the CNC system. If a certain part of the circuit in the numerical control system has poor anti-interference ability, it will cause a shutdown fault. And it can be found that the shutdown fault is caused by this circuit board. However, in an environment without interference pulses, monitoring will mistakenly believe that the shutdown fault has nothing to do with this circuit board.https://sheetmetal.top/
② If the interference pulse amplitude in the power grid is sufficient to cause a shutdown fault, and when the pulse amplitude is high enough, the fault will appear as a shutdown fault that is difficult to eliminate. The alarm on the CNC chassis often shows a hardware failure. If you follow this instruction, you won’t get any results.https://glovepuppetry.com/
③If the interference pulse in the power grid occurs quite frequently and the pulse amplitude is high enough, the fault will be difficult to eliminate and be a recoverable shutdown fault. The alarm on the CNC chassis often shows a hardware fault. If you follow this instruction and get no results.
