    Just to be clear, the static RAM and ROM will be wiped when they are pulled from the main board.

    At one point I felt I had nothing to lose with this board, so I pulled the board, unhooked the aa battery and pulled all the cards for an hour, in an effort to reset the whole thing. Unexpectedly it did help but also I kept the software and programs intact.

    Yes, there is a CF card installed, I can try to backup using that, thankyou, def worth doing.

    I have a feeling that a fresh board but swapping the eprom and the ram cards over might sort this, its worth a try before giving up no the robot.

    I'll report back in case anyone else is keeping one of these things going against all the odds!!

    Maybe a silly question but, I had assumed the memory is kept on RAM but, I see they are flash memory. Does this mean I could buy a new cpu and swap my existing eprom and flash memory card onto it and keep the same software and programs, possibly avoiding the issue I have at present which is now an intermittent failure to boot (TP stuck on initial screen).

    I was hoping to buy the whole thing, although I have two others here that had their own issues, so lots of cards that might be ok.

    The issue is I cant find anyone who can now upload the software onto these CPUs, it seems its just all too old now. If anyone has a contact I'd be grateful, this robot is just not busy enough to justify an upgrade.

    Hi, vintage robot user here. (m410 rj2)

    I have a pcu thats gone down, it is an A16b-3200-0042, it has an eprom with version 4.22 software on it.

    My question is, if I pick up a second hand part can I just swap out the eprom from my old board if the new one does not have the same version? I tend to drop a simple program in through the tp as its only palletising.



    Thankyou for your help on this. Having got to the bottom of the issue now and back to using a working robot again I can confirm the following findings

    SRVO-150 does indeed appear to be the fan in the top of the cpu. It looked fine but the run signal must have been weak or lost due to the age of the fan.

    SRVO-154 was a bit misleading, one of the control connections to the first servo amplifier was the cause, probably due to me decoupling the amplifier from the cpu next to it in order to fit a new old one.

    Cheers All


    Thankyou for coming back to me on this, it is happening from the off and the error wont reset to allow movement, I will check the three phases at each point next. The reason I hadn't before is that the 3 phase supply at the bottom of each amplifier and cpu does not appear to be applied until the contactors pull in, which cant occur due to the error status, it wont reset, so I assumed it must be the 240v supply.

    Really appreciate your feedback on this. Can you point me in the direction of the regeneration unit please, I haven't come across that before.



    Hi All

    First post but this forum has been SO helpful in the past as a surfer so thankyou.

    I know this is a really old robot, its a fanuc M410iwx on an RJ2 controller, but I would like to get a bit more life out of her yet if poss. I kept getting SRVO 150 error first then it developed the SRVO 154 after I opened up the cpu to check out the cooling fan.

    So far I have measured the voltage into the cpu at the connector input and its 239v, and also changed the cpu for a good second hand one (sold as working by a company at least). The SRVO-154 continues with the new CPU in place and also the SRVO 150 came back and went again after a switch off and on again.

    The old cpu showed a 2 in the display, the new one does not show a number.

    I'm a bit lost now but would really appreciate any input from members who may have had this in the past.
