数字量信号连接应注意的问题
变频器的输入信号中包括对运行/ 停止、正转/ 反转、点动等运行状态进行操作的数字量输入信号(开关型指令信号),这些信号常来自PLC 的数字量输出信号。PLC 通常利用其内部的继电器接点(继电器输出型P L C )或具有开关特性的元器件(晶体管输出型PLC)与变频器相连,得到运行状态指令,如图1 和图2 所示。在进行数字量信号的连接时应注意:
(1)使用继电器输出型P L C 与变频器相连时,应注意接触不良常带来变频器误动作,因此在实际接线中要注意连接可靠。
(2)使用晶体管输出型P L C 与变频器相连时,应注意晶体管本身的电压的高低、电流的大小等限制条件在其范围内,保证系统的可靠性。
(3)设计变频器的输入信号电路时,应尽量避免采用继电器等感性负载,因继电器开闭产生的浪涌电流可能引起变频器的误动作。
(4)当P L C 输出的开关信号进入变频器时,有时会发生外部电源和变频器控制电源之间的串扰,应注意对P L C和变频器分开接地,避免两者使用共同的接地线。
