    heidenhain tnc 2500 controller

    on my series 11 interact 11 when I try to reference the axises I get a drive axis fault. my voltage coming out of transformer T-2 is 185 off of the 2 180 legs & 385 coming off of the 380 leg. can somebody help me with this problem? If I go into manual mode the spindle will operate but none of the axis will operate.

    It sounds like you have a bad BOSCH axis drive board which the control is seeing.

    George how do I tell which board is bad? All three are showing the same l.e.d's lit up and when I isolate them individually I get the same response.
