我是新人小白,請(qǐng)大神幫忙我一下啊,看看我哪里寫錯(cuò)了呀,
三菱ST中DDRVA執(zhí)行后,DZRN無(wú)法回歸原點(diǎn)的問題,單獨(dú)回原點(diǎn)正常,執(zhí)行DDRVA移動(dòng)后,再執(zhí)行DZRN就無(wú)動(dòng)作 詳細(xì)請(qǐng)幫忙看看下面的程序

(*校準(zhǔn)螺距*)
Current_Distance := Pulse_Current_Distance / ONE_Pulse_Feed;
IF Calibration THEN(*如果校準(zhǔn)按鈕被按下*)
    ONE_Pulse_Feed := Calibration_Distance / Pitch_Setting * K100;(*計(jì)算1mm所用脈沖值*)
    DDRVA ( Calibration,Calibration_Distance,Feeding_Distance,Pulse_Output,Y001);
    Direction_Output :=TRUE;(*正轉(zhuǎn)方向啟動(dòng)*)
    IF M8029=TRUE THEN
        Direction_Output := FALSE;
        Calibration := FALSE;(*否則RST校準(zhǔn)按鈕*)    
    END_IF;
END_IF;

(*回原點(diǎn)*)
IF    NOT Backward_Limit AND NOT Enclosure_Not_Closed AND NOT Backward_Limit THEN
    DZRN (Back_Servo_Origin,K2000,K1000,Servo_Origin,Pulse_Output);
    IF Back_Servo_Origin THEN
    OUT_T(Scintillation=1,TC2,K10);
    OUT_T(Servo_Origin_Lamp =TRUE,TC1,K10);
        IF TC2 =TRUE THEN
            Servo_Origin_Lamp :=TRUE;
            IF TC1 =TRUE THEN
                Scintillation :=0;
            END_IF;
        ELSIF TC2 =FALSE THEN
            Servo_Origin_Lamp :=FALSE;
            Scintillation :=1;
        END_IF;
    END_IF;
END_IF;
IF Back_Servo_Origin THEN    
    IF Pulse_Current_Distance =K0  THEN
        Back_Servo_Origin :=FALSE;
        Servo_Origin_Lamp :=TRUE;
    END_IF;
ELSIF Pulse_Current_Distance <>K0 THEN
    Servo_Origin_Lamp :=FALSE;
END_IF;


最后在論壇的好心大哥幫助下,完美解決,提供修改的程序,幫忙大家避坑!!

IF Calibration THEN
    IF LDF(TRUE ,OUT_Puls_Monitor) THEN
        M340:=1;
    END_IF;
    OUT_T(M340=1,TC3,K100);
    IF TC3=1 THEN
        Calibration := FALSE;
        M340:=0;
    END_IF;
END_IF;

我自己頂一下，希望大神幫忙解決一下

這是c 單片機(jī)

這個(gè)的確是三菱PLC的ST語(yǔ)言編程;如圖

加個(gè)延時(shí)再觸發(fā)回原點(diǎn)

加了延時(shí)還是不行,不能回原點(diǎn),如下紅色字體部分

為什么不用梯形圖搞？

上一任程序工程師用ST寫的,我只能繼續(xù)用了,不然我要從頭寫,那頭發(fā)不保呀

M8029只接通到下一個(gè)功能指令就關(guān)掉了，你拿他來(lái)開定時(shí)器是沒用的

感謝提醒,已做修改.
問題還是無(wú)法解決,我明天對(duì)這段定位重寫試試
