Electrify of system of machine tool numerical control is checked, discover one chip is unusually calorific. The this chip power source after cutting off the power brings a foot to disconnect, static examination, it is normal that the block value that power source reachs the ground should be belonged to greatly. The block value that measures the power source of this chip to reach the ground is very little. Examine the type of this chip, for one nonstandard model, did not check in numerous manual, via circuit analysis, the main element in affirming its are this board () of annular pulse alloter. To acknowledge the problem of this chip further, change the pace that compression electricity power comparatives to be in charge of into drive of electric machinery power source above all, the power supply that renews this chip cites a base, enter electric machinery for ride instead of walk with glow diode circuit each winding makes imitate load. After electrify, glow diode is all bright, join each namely electrify, this is not to accord with circuit to ask, input pace does not have reaction into pulse, because this affirms this chip,already damaged. Do not have on this chip market, below the condition that inside driver housing the space allows, used assorted circuitry to go up with at hand namely already some D trigger and the combination that are not the door designed generator of an annular pulse, make go up in a small printed board, demolish original chip to install small printed board the solder in original chip through citing a base dish on, still glow diode makes imitate load, the pace is joined to press appearance sequence into pulse after electrify ordinal glow. Demolish imitate load, accept lead plane, electrify, it is normal that equipment moves. This exemple explains, maintenance technician wants to be able to analyse a phenomenon not only (shed) too, find out more obvious breakdown reason () of power canal attaint, can analyse breakdown deep step by step even first because of () of pulse generator attaint, and can be applied have yuan implement uncle combination replaces the problem of parts of an apparatus that is hard to solve.
