    PLEASE HELP SPINDLE PROBLEM

    Have Romi Centaur 35E with Fanuc OTC. problem is with spindle running speed readout on CRT will jump up which causes the feed to lurch to try to catch up. Physically the spindle speed does not change just readout on the screen. Have replaced the spindle motor, had the spindle drive serviced twice by different people, had the power supply serviced, and the spindle speed encoder. Cables checkout ok. Also does anyone have a parameter manual telling which bit does what?
    Thanks for any help

    Parameter #28 is 00110101 this matches the number in the original machine parameter book.
