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。
