Brake Number Conflict

    Robot gurus. I have a R-900iB700/R-30iB that suffered a crash to the motor of a group 2 aux axis. Long story short is the motor is no longer attached to the gear box (at least most of it anyway) and all cables of said motor have been unplugged (motor power/ encoder/ brake).

    We would like to move the robot to a better position to be worked on. With the motor removed we are seeing faults SRVO-069 and SRVO-068 which seem to (understandably) relate to the encoder. I can disable the group 2 motion in the TEST CYCLE screen which clears these alarms however another alarm pops up, SRV0-117 Brake Number Conflict. When resetting, it goes away for a few moments then comes right back. Where might I be able to tell the controller that the brake does not exist so we can move the group1 axis?

    Any chance you could hook up the aux axis and tie it up out of the way just to clear the alarms and move your robot? We have a robot with two motion groups that is now re purposed as a temporary material handler and just made a bracket to hold the servo allowing us to leave it plugged in. I know you said yours was broken off of the gear box but if the cables are undamaged this would work.

    Unfortunately the motor-side cables were indeed damaged, particularly the brake connector was ripped from the motor. The motor itself has been shipped out for repair so we don't actually have one to hook up.

    The brake group setting appears to be what I'm looking for. I did find how to get in to the Controlled Start menu, though where might I find the brake group setting?

    First, take an image backup.

    Do a controlled start, which with an R30iB, the easiest way is to press FCTN, then 0 for next, then 8 for cycle power, then select options and CRTL for controlled start.

    Once in a controlled start, press MENU, then 9 for MAINTENANCE. At this menu, you should be able to adjust the brake settings, or, if it were my robot, I would just delete the axis for the time being and then restore it with the image backup once you have all of your repaired hardware returned.

    When you do restore the image, after repairing the bad axis, you will have several faults, because the robot is in a different position. Fanuc will tell you to remaster the robot, but all you need to do is a single axis master of the now rebuilt axis, and then go into system variables, then to $DMRgroup, then set master_done to TRUE. At that point you can go back to the mastering page and calibrate.

    This got to be rather long winded, please ask if you need clarification on any of these instructions.

    Found it, thanks!!

    Ok next issue. I've attempted to do the img backup to a USB through the normal screen and through the controlled startup. Both times it failed around the mid 20s file count. Any encounters of this before?

    For clarity, I'm fairly new to this site. I don't believe they have current backups nor have I ever tried to take them on this particular robot.

    You can't take an image backup from the USB port on the TP it has to be plugged into the controller USB port for an image. Make sure your USB is properly formatted to FAT(32) you can do this on a PC or on the TP itself. Then plug it into the controller and follow these steps.

    MENU>FILE>1.FILE

    F5 for Utilities and select 1. Set Device

    Select USB Disk (UD1:) which is the controller port.

    Then hit F4 [BACKUP] and select IMAGE

    Tried on both controller and TP. Good to know img only works on controller port though. I'm suspecting something is up with my usb. It is FAT32, but I can't reformat it due to needing other stuff on it at the moment. Will try and get another usb soon.

    Best bet is to have a USB with nothing at all on it as it's a lot easier to do. Otherwise you need to create a folder and select it through the robots file menu. I'm going to PM you with some info on how to do this automatically using a command file that i've found on these forums.

    "I could tell that my parents hated me. My bath toys were a toaster and a radio."

    yeah mine is a 128GB. So I ended up using the PCIA slot with an adapter to a CF card that our maintenance team had. Worked like a charm so was indeed something to do with the USB itself.

    After that, went back to the procedure of turning off the brake (opted not to delete the axis at this time!) and was able to then clear all the faults and move Mr. Robot in to an easier position to be worked on.

    Thanks for the help!

    Could you tell me how I could do that variable is or something ... I had a similar problem ... Thank you
