  • Problem with a krc4 compact cabinet

    Quote from SkyeFire

    Does the fan plug directly into the motherboard? If so, VOLTMON FAIL suggests that the fan failure managed to damage a voltage regulating element on the motherboard, enough that the CPU and/or peripherals are not getting correct voltage to boot.

    Yes, it is plugged directly. Sounds logical, not sure how i can check it. Will look around for microelectronics specialist to try it out - cannot se other option :frowning_face:
    Thanks!

  • Problem with a krc4 compact cabinet

    So what i tried - removed the bios battery, triyng to reset the memory somehow ... just to make sure this is not some error saved somewhere there and preventing the start of the controller.
    I am planning to feed 27V voltage to the CPU fan externally (leaving it in its socket to be able to send RPM information) just to check if the lack of fan rotation is preventing the startup of the PC
    What i am thinking is may be the power feed line to the fan was overloaded and may be burnt and it is unable to drive it now. Not sure where to look for this as i am struggling to find information about this motherboard - even basic manual with description of the main functions - it is Fujitsu w26361-w4143-z4-02-36 or at least that is etched on it

  • Problem with a krc4 compact cabinet

    Hello,
    i have a problem with a motherboard (D3445-K11 GS1) of a KRC4 compact cabinet, manufactured 2018. There were around working 100hrs on this robot, used only for exhibition and development purposes.
    The robot was working ok, until a plastic strap went between the blades of the CPU fan. The fan stopped, so did the cabinet and never came up :frowning_face: . When i started it up there is a red led glowing around the USB ports (photo attached) with signage next to it: VOLTMON FAIL. Attached an external monitor and there is no signal from the cabinet at all.
    I tested the fan - it is working fine. Also replaced the motherboard with another one and the robot is ok.
    My question is - is that a repairable damage? Is there something i can do to revive the robot or a new motherboard is needed?
    I suppose the damage is due to the fan overload and eventually the voltage supply damaged/dropped or something.
    Any ideas where i can look will be appreciated!
    All the best!

  • MOTHER BOARD - FTS D3076-K - KRC4 - FAIL LED ON

    Hello, what was the solution in your case? Did you managed to fix this? I have the same problem with a KRC4 compact cabinet - the robot was working fine untill a small piece of plastic went into the fan and stopped it. Afterwards we have a red led and no signal on the motherboard.

  • Stop due to locked drive A...?

    Hi again!

    As i never used krcdiag before, feel a bit lost... on the end i think i found how to see the errors but they are not telling me anything usable.

    I exported them so if someone can tell me what these registered errors mean...

    here is a part of the messages:


  • Stop due to locked drive A...?

    Thanks guys! I was really out of options with this " locked " messages... i will dig in the plc logic - we use it for all the ext signals, may be there is a glitch in the logic? Will check the logs and lets see where this will go...

    Thanks again! Unvaluable help!

  • Stop due to locked drive A...?

    Hello, i have a problem with a KRC4 robot:
    KRC4 KSS 8.2
    KR180 R2500 Extra
    The robot is doing palletizing and was ok before the installation - we tested it for a week.
    The robot is working in automatic external as a device with a PLC controller Siemens S7 1200 as master.
    All the signals for the gripper and the conveyor system + sensors are managed by the PLC.
    We have this error: " Stop due to locked drive A4 "
    where the locked axis can be anything from A1 to A6 - it is different all the time. The message cannot de acknowledged in EXT mode :frowning_face:
    The issue is appearing at random position, there are no singularities over the whole range of movement of the robot.
    Any idea what can cause this? I am struggling to find any info about it :frowning_face:

  • KUKA BendTech

    Quote from massula

    This is pretty odd, since this document itself isn't appearing in Xpert as well.

    But a quick look in this document gave me the impression that this new BendTech 6.0 is something specific from KUKA Automatisering + Robots N.V. branch (Belgium), not a package sold by KUKA main branch.

    Do you know if they are selling the app?>

  • Kuka robot moves in the wrong direction

    Hello, a bit late answer from me, but i hope it will be helpful in your future andventures with this robot and Sprutcam.

    To have correct position and values of the virtual model in Sprutcam and the real robot you need to measure and match the tool TCP and orientation. Sprutcam have very useful tool - android app - where you can enter the data of two measured tool - long and short one. Then the app calculates the value of the A B and C and also inserts them in the robot scheme in the Machine maker.

    In your case first of all - do your part of the work and make (or ask somebody to do) as precise possible the laser head - that will give you much better experience when you program the robot and also will help you to prevent any eventual damages to the laser head - Sprutcam is really good in collision avoidance.

    I hope that helps, if you need more info - ask here, or you can also ask your Sprutcam reseller to help - the initial setup needs some experience
