    numc_board sys_fail . Error on Hitachi Seiki VK45-2

    Hi Guys,

    having troubles with my Hitachi Seiki VK45-2 with Seicos control. The control does not start up saying NUMC_BOARD_SYS_FAIL . Then it shows "table checksum failed". I assume that the problem is in control board and already called for a fellow guy who specialise in cnc controls but maybe some of you already have gotten such an error ?

    Hello
    could be the board itself, the NUMC are faulty at times. If you are getting this alarm randomly you can try to re-seat the NUMC and see if its a connection issue. Try that and report back

    Just got back to the shop. Had reset NUMC and SPHC boards and do not know what to do further - it's just sends these errors (on attached photo) and i cannot clear them and go further than that screen (i assume that i need to set all the parameters back but cannot proceed to that menu)
