一、分析控制對象、確定控制要求
1.對M1電動機的要求:單方向旋轉,有過載保護;
2.對M2電動機的要求:全壓正反轉控制,點動控制;啟動時,先啟動電動機M3,再啟動電動機M2;停機時,電動機M2先停止,然后電動機M3才能停止。電動機M2設有必要的互鎖保護;
3.對電動機M3的要求:全壓正反轉控制,設*過載保護;
4.電動機M4容量小,由開關SA控制,單方向運轉;
二、確定I/O點數(shù)
根據圖1找出PLC控制系統(tǒng)的輸入、輸出信號,共有13個輸入信號,9個輸出信號。
三、繪制I/O端子接線圖
根據I/O分配結果,繪制端子接線圖
四、設計梯形圖
1.控制主軸電動機M1的梯形圖
梯形圖如圖2所示。
2.控制電動機M2與M3的梯形圖
?、贀u臂升降過程
?、谥鬏S箱和立柱箱的松開與夾緊控制
