    ds0309(x1) APC ALARM: ref. return impossible

    hie all,
    in marshall roboturn xl machine there is 4 cnc's having oi td series with one robo and in one cnc machine displaying alarm( DS0309(X1) APC ALARM: REF. RETURN IMPOSSIBLE) at time of refrencing, if i try to set APZ to 1.
    If i set APZ to 1 by first set APC to 0 then APZ to 1 after that APC to 1, but after swithing power off and on APZ changes its state to 0 from 1 automatically.
    i also done steps written in maintenance manual(B-64305EN/04) (PAGE NUMBER 488) but problem not solved

    also in this cnc we use one encoder and one magnetic scale in X axis.
    also alarm comes in x axis
    z axis is alarm free
    *****here we use only 2 axis(X and Z) *********
