TR_HWERR, CPU Fail Error [Fail Safe] !

jaymunday
I have recently been getting this error "TR_HWERR, CPU Fail Error [Fail Safe] !" Sometimes the machine start comes back on & sometimes I have to let it sit for a while. After getting this error this morning I shut everything down & rebooted the controller & computer. That worked but now I am getting a "TR_FG16e,Overspeed Error". As of right now I can only run thr CMM on 10% speed.


PCDMIS 3.7MR2
Global image 5-7-5
  • Sounds like an issue in the controller itself, like, maybe, the vents are clogged and/or there is a ton of dust inside it.
  • The overspeed error should also indicate which axis has the problem...
    From the user manual :

    The firmware has detected that the speed error (speed obtained from the counts with respect to the
    speed command sent onto the D/A) has exceeded the maximum limit allowed. It may be due to a
    motor overload owing to obstacles to motion (collision, friction), a motor failure, a failure of the
    motion mechanical system, of the servodriver, of the position transducers or of the tacho. Lastly, in
    case of a first connection of the controller to a machine, it may also be a wrong servo adjustment or
    the parameter MAX_LAG of the CONSTANT has a small value.    ​

  • tr_hwerr cpu fail error ditto. Waiting on Support to call back. I thought I'd check the forums. 

    Nexus (HXgN) has hidden the forums so deep, then there wasn't a magnifying glass to search!? What kind of forum is this? lol

    So my error happens intermittently but has been increasing frequency throughout the day. Now the B&S global ancient machine is unresponsive. I cannot home the machine; I cannot open a program (offline either) because PCDMIS wants a CMM present. annoying. 

    LATER THAT DAY . . 

    I found a bad cable running off the JOG BOX. This was the likely culprit. I'm googling rs-232/485/422 cables now to find a good repair option. Good Luck everyone who makes it this far

  • Shut controller down. Open the controller's vent filters and vacuum them or replace the media.  Then go to each component box and vacuum the inlets and outlets. 

    There's no guarantee this will work, but it certainly will not hurt it.

    As for the jogbox short, as long as the orange cable to the jogbox isn't the issue, you can bypass the main umbilical's wire entirely between the controller and the machine's plug, by plugging NJB the jogbox directly into the controller, bypassing the bad wire/connection. 

    On my DC240, we had a UJB jogbox, (the hideous one with the touchscreen) just take a dump on us.  The machine's controller wiring had some cable adapters in line just before the controller, and in order for me to utilize our spare NJB jogbox without hexagon coming on-site, we simply bypassed all of the other wiring and plugged the NJB's cable directly into the controller's "JOG-XS9" port.  works great.
