数控柜故障排除方法以及检修实例,在《电加工》杂志以及其它资料上均有介绍。但对由微分电容引起的故障却介绍不多。下面选其几例与同行们商讨。 (1)置数报警,关T_(KS) 此时,送其它数码,以判别是奇偶校验P_(Ω)出错还是S寄存器的故障。经检查可置偶数码(2、4、6、8),但对奇数码(1、3、5、7、9),却报警,关T_(KS)。由面板指示及逻辑判断可知T_(SI)为常“0”态。检查后发现是由T_(SI)置“1”端的微分电容击穿所致。由于送数前的置“B”码已经把T_(SI)置为“0”
CNC cabinet troubleshooting methods and maintenance examples in the “Electrical Processing” magazine and other information are described. But the fault caused by the differential capacitor is not much introduction. The following selected a few cases to discuss with their colleagues. (1) Set the number of alarms, off T_ (KS) At this point, send other digital to determine whether the parity P_ (Ω) error or S register fault. After checking the even number can be set (2,4,6,8), but the odd number (1,3,5,7,9), but the police, off T_ (KS). T_ (SI) is always “0” state by the panel indication and logic judgment. Inspection found that the T_ (SI) set “1” side of the differential capacitance breakdown caused. T_ (SI) has been set to “0” because the “B” code before sending the number has been set
