    PMAC PC Saturated output on All DAC channels

    in Pre-Turbo PMAC

    Posted

    I have a 602191-104 PMAC PC in a 5 Axis Fadal Mill . After Trouble Shooting Multi Axis Runaway , I have saturated Analog Output Voltages from all the DAC channels . Even with all Axis stable with feedback. The Control was just received back from the manufacturer, they also sent out a senior tech and he came to the same conclusion.

    I do know that the 60Pin cable on the J8 machine connector was initially installed incorrectly , ( cable has no locating tabs ) .

    Could this have damaged the DAC IC's ? The DT board use the PC Power Supply for all its power , No External Power Source .

    Could I have a jumper setting on the board Incorrect , causing my problem . All I variables and M variables seem to be correct . Or is it a case of fried hardware. Dwayne
