VK 45 II NUMC BOARD ERROR

Hello,

I am having a problem with my VK 45 II with seicos M3 controller. It started a couple of weeks ago showing randomly NUMC board error on a daily basis both when the machine was running a part or on standby. This made the machine go on e stop.
Starting today when ever I press MDY button on the panel the error appears :NUMC SYSTEM FAIL, Software error occurs in the NUMC board . All the other machine functions and buttons work ok, but I can't start a program in memory mode.
The machine data and parameters are ok, I even scrolled trough the ladder diagram to check for changes but nothing. When the error occurs there are 2 red led s on the NUMC board number 3 and 5.

Thank you

Hello
the NUMC is failing based on what you are describing (and what the controller is telling you). This is a common fail-point within the SIII controller. Best thing is to backup you NC now;
LED3 is FAIL and LED 5 is SOFTALM
If you need further assistance please PM me and I will help; there is a process that needs to be done before swapping parts

Its also possible the NUMC software is failing that is on the EPROM ( I have seen it only once or twice in my experience) but its a possibility.

Hello John,
Hitachi Seiki periodic alarm 1107 occurring in the Seicos M3 indicating NUMC System Fail - CPU HLT occurs in the system board. Is it worth reseating the board and retrying thanks? If so, I would have to back up as mentioned above, I think you mentioned that there is a procedure. regards Dave

Did you find a resolution to the NUMC fail
