  • power off controller

    The charger and the batteries are on the A2, connected with two cables.

    If the batteries are non-rechargeable, I don't know how you can skip the charger.

    I suggested to KUKA once to replace the NiCd with Pb and they said "no, because the charging cycle is designed for NiCd and anything else will stress the charger".

    NiCd between 1200 and 1600mAh is OK, but don't go higher. KUKA said that bigger capacities will also stress the charger.

    I'm sorry, I haven't received any files. But if there is no .LMD in there, you will have a hard time

    I have files for the robot.

    I have several laptops but...

    The installation must be done with Windows 95 or 98. The laptop must be a very old model to have the comport and be able to install Windows 98.


    archive file with .lmd extension? - can you tell me in more detail what this file is.

    Perhaps you can load Win95 inside a Virtual machine. This is how we used to work with these robots/

    For the serial port you can use USB->Serial adapter. Most of them work well.

    The complete image of the software is a file with the extension .lmd. Perhaps you have that in the files that came with the robot...

    You see this board that says A2?

    Carefully remove the cables, unscrew the two big screws up and down and slide it out towards you.

    Inside you will find the two NiCd packs. These need to be replaced in order for the robot to keep the mastering.


    But for now, there is no software in the robot.

    Do you have a laptop, serial cable with DB25 plug and a backup file with the extension .lmd?

    even "ALERX STOP"? :winking_face:

    :face_with_tongue:

    The KRC32 had two batteries

    - Inside the A2 board, it had two NiCd packs, totaling 24V. Their job was to supply the resolvers for a couple of seconds until their values were stores into the system. If you lose the batteries, you lose the mastering; no big deal.

    - It had also a small battery box, with 3x alkaline 1.5V AA batts whose job was to suppy the eprom on the main cpu. That's were everything was stored. Programs, vars, the KSS of the era, everything...


    Leaving the robot running for hours, makes no difference, because the important batteries are non-rechargeable alkaline.


    Unlike modern KUKAs, you exchange the 1.5V batts only with power ON. Otherwise you loose everything. The error message in this case is

    A 217 /:EMERGENCY STOP FROM ACR

    (ALARM STOP) <-- "ALERX STOP"

    and you have to connect a laptop and re-upload everything (something like today's WoV)


    As for the orange battery light....

    On the cabinet one can see some buttons.

    There is this...




    and there is that...




    When the controller is powered ON, one light comes on for a couple of seconds, indicating that the system is booting.

    I cannot remember which one is it. But both icons can be misleading as "battery low".

    What looks like battery, is actually referring to Drives ON and what looks like thunder is Fault.


    KRC32....unforgettable experience :smiling_face:

  • How to make E2 jog faster in T1

    Hello everybody,


    we have installed a new KRC5, KSS 8.7 with two external axes. The ext servos are pretty big, MG_180 and MG _160

    Everything works great in AUT. The ratios, the rpm, the speeds, the ramps.....I'm not an expert, but it sure looks like there is nothing that needs to be changed.


    However, we have a complaint from the customer, that the E2 moves pretty slow when jogging in T1. Sometimes he needs to manually rotate the E2 back to zero (0) degrees and he hates the waiting.

    Is there a parameter to increase the jog speed of only E2, without affecting anything from its behaviour in AUT ?

  • how to connect collision box CAT2

    Hello all,


    we are integrating a brand new welding 120iD, equipped with a CAT2 shock sensor from Binzel. The shock sensor is basically a single normally close contact that opens if the torch accidentally touches an object.

    With other robot brands, we usually connect this signal to something like "motion enable" or "stop".

    As we are not very experienced with Fanuc, where do you usually connect this signal? It is not a complicated setup. We use the buttons on the controller to start a program. No PLC or anything ...

  • KRC5 - Reduce override during Arc welding

    Hello All,


    we are working on a

    KRC 5

    KSS 8.7.5

    ArcTechBasic 3.5


    The manual clearly states that "Program override is automatically set to 100% when the welding process is activated".


    But of course, there is always a customer with a special reason that needs to disable that.

    Do you know how to disable this feature, please? We want to be able to reduce the override during welding.

    (by pressing the minus softbutton, it is reduced only for a fraction of a second before jumping back to 100%)

  • XRC alarm 0200 - Memory error (parameter file)

    Hello people,


    we have an old XRC that displays major alarm 0200 Memory error (parameter file) and the words "Maintenance Mode" at the very bottom left of the screen.

    I assume (or hope) that it has happened due to battery failure. I wouldn't like to believe that it is a breakdown in the electronics.

    We have a full backup incl the .hex files

    May I ask if you have the procedure to guide us recover, reinitialise, reinstall, (...I don't know which is the right word) the system?

    We would like to give it a try ourselves before calling Motoman


    Many thanks in advance
