sign在电路中什么意思

SIGN就是signal的缩写，是信号的意思。

伺服驱动SIGN就是：伺服驱动信号的意思了。

脉冲信号，是指外部控制器如PLC输出口信号线连接到伺服驱动器的puls sign口。

puls是脉冲，而sign是用来控制伺服电机正反转用的。例如：PLC输出口Y0，ON时伺服电机正传，当想要反转是Y2必须也要ON，也就是说伺服电机正传时Y0 ON，反转Y0，Y2都要ON。

在三菱plc输出为晶体管的情yo和y1都可以用做脉冲发送信号同时也可以用做方向符号，所以说y1做为脉冲信号，y2做为方向符号是可以的。三菱这样的plc可以同时驱动两台伺服。

词语用法：

1、sign用作名词时有“记号”的意思,转化为动词可作“签名”解,一般指人在文件、信件上签署自己的名字; sign作名词还可作“手势”解,转化为动词则是“做手势”的意思,指由于某种原因不能用语言表达或不想用口头方式交流的情况下用手势来表达某种意图。

2、sign可用作不及物动词,也可用作及物动词。用作及物动词时,接名词、代词、that从句作宾语,还可接以动词不定式充当宾语补足语的复合宾语。

3、sign作“签名,签字”解时可用于被动结构,作“发信号,做手势”解时不用于被动结构。

词义辨析：

sign, groan, moan, sob这组词都有“叹息声，叹息”的意思，其区别是：

1、sign 多指无意识地发出表示沮丧、悲痛、悔恨或厌倦等情绪的深沉叹息。

2、groan 侧重指因受到难忍受的精神负担或强烈的痛苦等而发出沉重的呻吟，也指显示强烈不满的叹息声。

3、moan 语气比groan强，多指拉长的或连续的悲叹(声)或呻吟(声)。

4、sob 指抽噎声或呜咽声，或边说边哭。

在c语言里面,非零就是真的意思,零就是假的意思,sign=0,就是将0赋值给sign,或者是将sign赋值为假,!sign就是真的意思,顾名思义,sign就是标记的意思,在程序里面有的时候要设立一个标记来确定程序过程中是否改变了某个值,比如说是判断奇偶数的程序什么的,算法不同用处也不同,不过还是比较有用的~但是再Java里面就不能用0和非零来表示真和假了,那里面boolen类型和整型有了严格的区别
