RJ3 Servo error 230/231

    I have a problem with a Fanuc RJ3i S430i system.
    I am getting alarm SRVO 230 and 231 saying 24 and 0v chains are abnormal.
    I have a reference manual for programming, but this refers to MAINTENANC MANUAL B--81465EN if simply releasing and squeezing the dead man's switch doesn't work.

    I'm not too familiar with Fanuc so this could be something simple I'm overlooking. This is a training robot and I have come to work (unpaid) to familiarise myself with these robots and have been assured that it has been working in the past.

    Any help much appreciated, as always.

    Apparently it's quite common.

    Menus>System>Type>Config

    Scroll to 28-Reset CHAIN FAILURE detection :False
    Set to TRUE.
    This will stay true for a second or so then go false again.

    Reset and try again.
    If this doesn't work depress and release Estop then try again.

    You HAVE TO keep pressed any e-stop because SRVO-230 can be due to a mis-synchro on open or close phase to any 2 channel contact (relays on redundant and/or Operator Panel).
    Is it fix or you can reset and then appear again? i.e. when pressing a deadman or enabling TP.Just 2 b sure do procedure with keyswitch on AUTO and TP OFF, doing this you'll exclude deadman safety chain.

    of course hw failure can be the cause: Operator Panel, Redundant, TP, TP Cable.

    cheers

    if it is a frequent problem for a cell, consider automatically resetting the chain fault.

    BG_LOGIC

    $MCR.$CHAIN_RESET=(SI[1:Fault Reset] OR UI[5:Fault Reset])

    Hello ,

    I also have a frequent problem with srvo- 230 alarm, and it s causing us dead time.
    Robot controller is RJ3iB version 6.1 so I dont have BG logic. Instead, I created an autoexecute program .

    The problem is that I cant set $MCR.$CHAIN_RESET equal to UI[5:Fault Reset]);

    When I select ''Paramenter Name " I have only R,constant, AR , PR to choose from. I also cant do this from I/O.
    Maybe it s not possibile in this software version?!

    Thanks in advance!

    canvis,
    I have the same problem with my robot. I searched a lot about it but I couldn't find any solution. Set $MCR.$CHAIN_RESET equal to UI[5:Fault Reset]); The software version of my robot because it can't be found in this setting. If you find a different solution I would be glad to share it.
    Respects..
