}}}我们要讨论解析后我们数据存储的问题,其实在资源比较足够的情况下或者能够挤出data区的情况下可以考虑用结构体,我们构造好相应结构体,将接收到的数据存储进去,要应用的时候就十分方便。
但这也有个矛盾,一般c51定义的结构体都被存储在data区,一般通讯的字节量大空间必然不够,存在一个矛盾,可以采用联合体union进行存储效果会好一点。
当然也可以在保存数据时采用定义在xdata区(片外)的buffer来存储。

安装要求1)发热和散热能力决定变频器的输出电流能力,从而影响变频器的输出转矩能力。
2)载波频率:一般变频器所标的额定电流都是以最高载波频率,最高环境温度下能保证持续输出的数值。
降低载波频率,电机的电流不会受到影响。
但元器件的发热会减小。
3)环境温度:就象不会因为检测到周围温度比较低时就增大变频器保护电流值。
4)海拔高度:海拔高度增加,对散热和绝缘性能都有影响.一般1000m以下可以不考虑。
以上每1000米降容5%就可以了。
