1、PLC的開關量信號控制變頻器

PLC（MR型或MT型）的輸出點、COM點直接與變頻器的STF（正轉啟動）、RH（高速）、RM（中速）、RL（低速）、輸入端SG等端口分別相連。PLC可以通過程序控制變頻器的啟動、停止、復位；也可以控制變頻器高速、中速、低速端子的不同組合實現多段速度運行。但是，因為它是采用開關量來實施控制的，其調速曲線不是一條連續平滑的曲線，也無法實現的速度調節。

2、PLC的模擬量信號控制變頻器

硬件：FX1N型、FX2N型PLC主機，配置1路簡易型的FX1N-1DA-BD擴展模擬量輸出板；或模擬量輸入輸出混合模塊FX0N-3A；或兩路輸出的FX2N-2DA；或四路輸出的FX2N-4DA模塊等。優點：PLC程序編制簡單方便，調速曲線平滑連續、工作穩定。

缺點：在大規模生產線中，控制電纜較長，尤其是DA模塊采用電壓信號輸出時，線路有較大的電壓降，影響了系統的穩定性和可靠性。

3、 PLC采用RS-485通訊方法控制變頻器

這是使用得為普遍的一種方法，PLC采用RS串行通訊指令編程。優點：硬件簡單、造價低，可控制32臺變頻器。缺點：編程工作量較大。

4、 PLC采用RS-485的Modbus-RTU通訊方法控制變頻器

三菱新型F700系列變頻器使用RS-485端子利用Modbus-RTU協議與PLC進行通訊。優點：Modbus通訊方式的PLC編程比RS-485無協議方式要簡單便捷。缺點：PLC編程工作量仍然較大。
