3、 模拟量信号连接应注意的问题变频器中的模拟量输入信号，通常指0～10V/5V 的电压信号或0/4～20 ｍＡ的电流信号；这些模拟量输入信号可通过接线端子由外部给定，当变频器与P L C 连接时，这些模拟量输入信号也可来自PLC 的模拟量输出信号，如图3 所示。在进行模拟量的连接时应注意：

（1）阻抗匹配。根据变频器的输入阻抗选择P L C 的输出模块，实现两者的阻抗匹配。

（2）电压范围。当变频器和P L C 的电压信号范围不同时（如变频器的输入信号为0～10V，而PLC 的输出电压信号范围为0～5V 时；或PLC 的一侧的输出信号电压范围为0～10V而变频器的输入电压信号范围为0～5V时），需采用串联电阻的方式进行分压，以保证两者在正常电压范围内

工作，避免电压过限可能损坏器件。

（3）采用屏蔽电缆或绞合电缆。对于变频器和P L C 而言，弱电控制信号（电压0～5V/10V、电流0/4～20ｍＡ等）易受到外界强信号的干扰，对控制信号采取适当的屏蔽措施。常用的方式就是采用屏蔽电缆进行屏蔽；对于长距离的控制回路宜采用绞合电缆，绞合电缆的绞合间距尽可能小。

（4）主、控电缆分开布线。实际连线时，注意主、控电缆分开布线，且相隔的距离。以保证主电路侧的干扰及噪音影响不到控制电路。
