永宏plc回原點程序MD0模式

    永宏PLC回原點程序MD0模式

    近點信號X0,左極限信號X1,清零輸出Y5,歸零方向為從右→左。

    簡述:1)當電機落在X0右邊時,電機由右→左運動,當靠近X0時(上跳沿中斷),速度由復歸速度變為爬行速度當電機離開X0(下跳沿中斷)瞬間,立即輸出歸零清除信號Y5,同時把原點數值搬至DR4088,歸零完成。

    2)當電機落在X0和X1信號之間時,電機向左極限信號X1運動當碰到X1時,電機反向運動,向X0近點信號靠近,當離開X0瞬間(下跳沿中斷),電機改變方向,變成向左運動,然后重復1)的動作。

    該模式下,歸零完成后,DOG信號在電機右側。
