1.7 将电磁干扰问题(EMC) 影响减为最小的措施
通常，好的安装经验可以确保控制器安全和无故障运行。然而，如果遇到问题，请参考以下的建议及相关措
施。
1.7.1 确保电柜中的所有设备接地良好
使用短和粗的接地线连接到公共接地点或接地母排上。特别重要的是，连接到变频器的任何控制设备（比如
一台 PLC）要与其共地，同样也要使用短和粗的导线接地。最好采用扁平导体（例如金属网），因其在高频
时阻抗较低。电机电缆的地线应直接连接到相应变频器的接地端子（PE）。
1.7.2 控制电缆最好使用屏蔽电缆
一般来说，控制电缆的屏蔽层应直接在变频器的内部接地，另一侧通过一个高频小电容（例如3.3nF/3000V）
接地。当屏蔽层两端的差模电压不高和连接到同一地线上时，也可以将屏蔽层的两端直接接地。信号线和它
的返回线绞合在一起，能减小感性耦合引起的干扰。绞合越靠近端子越好。模拟信号的传输线应使用双屏蔽
的双绞线。不同的模拟信号线应该独立走线，有各自的屏蔽层，以减少线间的耦合。不要把不同的模拟信号
置于同一个公共返回线。低压数字信号线最好使用双屏蔽的双绞线，也可以使用单屏蔽的双绞线。

1.7.3 布线
电机电缆应独立于其它电缆走线，其最小距离为500mm。同时应避免电机电缆与其它电缆长距离平行走线，
这样才能减少控制器输出电压快速变化而产生的电磁干扰。如果控制电缆和电源电缆交叉，应尽可能使它们
按90度角交叉。同时必须用合适的夹子将电机电缆和控制电缆的屏蔽层固定到安装板上。
1.8 散热问题
• 电柜里的发热源，如驱动模块的四周要留有散热空间。
• 电柜与外部的通风要保持良好，有条件的要安空调。
