    How to replace servo drive in HITACHI HG400III

    Hi!
    I have HITACHI HG400III, 1999, Seicos 16.
    I replaced XZ driver A06B-6096-H208 to new.
    It is 2 axis driver (L-M)
    Try to switch on the machine. Till "STANDBY" button all is OK.
    But after press this button all drivers show "5" in LED indicator.
    I checked axis table in working HITACHI HG400 and compare it with my machine under repair.
    The difference is in photo.
    Looks like SEICOS did not initialize driver and X and Z axis try to use A1-L driver together. In working HITACHI X use A1-L but Z use A1-M driver.
    Please help
