1、变换为可调电压、可调频率的交流电装置。变频器广泛应用于节能、自动化系统及提高工艺水平和产品质量等方面。变频器的问世,使电气传动领域发生了一场技术革命,即交流调速取代直流调速,变频调速被公认为有发展前途的调速方式。
可编程序控制器简称PLC(Programmable Logic Controller),它是一种数字运算与操作的控制装置,广泛应用于工业控制的各个领域。PLC 通过软件编程和硬件连接可实现复杂的控制任务,控制功能强大,是当代工业控制的三大支柱之一。作为工控产品,变频器和PLC 常配合使用(PLC 作为编程器,变频器作为驱动器),完成控制任务。
P L C 与变频器的连接主要方式有:PLC 的数字量输出信号与变频器的数字量输入信号相连;PLC 的模拟量输出信号与变频器的模拟量输入信号相连。实际应用中,就两者正确连接时应注意问题总结如下。同时,变频器运行时会对周围电气设备产生较强的电磁干扰,为防止变频器运行时对PLC 干扰,两者相连接时应重点考虑的问题总结如下。
