The hottest short circuit, why are you still walki

Why are you still walking when there is a short circuit?

the machining gap voltage is sampled to the frequency conversion circuit, and the frequency conversion generates signals of varying speed to servo feed, that is, whether you walk or not, and whether you walk or not, fast or slow is determined by the gap voltage. There are roughly two situations when the short circuit is still running. One is the average speed feed that is not controlled by the gap voltage. This is because a DC voltage of manual feed is forced to the frequency conversion circuit. At this time, the characteristic is that the feed speed is constant, not controlled by the wire barrel commutation, and regardless of the gap voltage. Because the purpose of setting the manual gear is to disengage the gap voltage control and read the spring force of the stroke on the pressure gauge. Second, walk slowly at a very slow speed (about oneortwo seconds or even a few seconds a step), which is usually because there is a voltage drop between the sampling point and the short-circuit point. This low voltage value accumulates in the frequency conversion circuit, or a little leakage of the frequency conversion circuit itself forms a few ACR foaming processing aids jumping step by step in 5.0 ~ 8.0 seconds. In addition, the impurities of the material being cut or the low conductivity of the material itself also make the sampling circuit unable to get a short-circuit signal, so it is difficult to cut the material with a large amount of impurities, and it is also conditional that the material with low conductivity can be cut. This is the reason why some special material cutting should take corresponding measures (even in addition to the report of automatic and manual analysis modes 2002 provided by the initial analysis board, the hardware structure should be modified)
