    Alarm when calling same tool. Fanuc 18i-m Mitsubishi M-V5Cn-L

    Hello everyone.
    We recently acquired a Mitsubishi M-V5Cn-L machining center with Fanuc 18i-m control, and can't seem to figure out how tool change works on it.
    Problem is whenever we try to call same tool that is already in the spindle, it throws an error "NO. 2058 Not Tool Command"

    So for example if my program finished with T01, and I try to call out "T01; M06" in the beginning of the program, it throws that error.

    Anyone has seem this happen on their machines? Any help will be appreciated.

    Thanks

    It's not unheard of to have a Fanuc control throw an error in this situation. I have an OMC that throws an error when the tool is already in the spindle. I have an 18MC that ignores it if I'm remembering correctly.

    There are many ways to work around this. If not using block delete anywhere in the program, add a block delete ahead of the tool change at the head of the program.

    Another way is to start with T1 in the spindle and do not program a tool change at the head of the program.

    Finally is to change to a blank tool at the end of the program so T1 is reloaded at the beginning of the program.

    The first two of these options leave a small window of potential for accidents if for some strange reason another tool is manually placed in the spindle between one run and the next. Depends on your operational procedures if this potential is worrisome or not.

    Not sure if there is a parameter to change this or not. I have a feeling it's a thing chosen by the machine builder. Look in your documentation for an answer to that.

    the_gentlegiant,
    Thank you for the reply. So at least now I know its not something fundamentally wrong with the machine.
    I have another Fanuc machine that will just ignore/skip thru redundant tool changes, so I was surprised that Mitsubishi would just alarm out.
    There's nothing in the documentation that mentions anything like that.
    I will try contacting Mitsubishi and see what they say about it.

    the zone and industry arena were the same forum, only skinned differently. Now you have to jump through hoops to see industry arena that you didnt have to in the past.

    You toolchange issue is in the way the MTB wrote the ladder. Believe it or not "it is a feature not a bug" is probably true.

    I am looking forward to see what DrDos does to change this behavior.

    I found it on Industryarena. Is Keep Relay K4.5 on or off?

    drdos,
    Looks like Keep Relay K4.5 is off.
    Please see picture attached, to make sure I highlighted correct keep relay.

    Thanks

    Yes that is the correct bit. Try changing it to 1 and see what happens.

    DrDos,
    Good news, I tried changing Keep Relay K4.5 to 1 and it works now!! It simply goes right past redundant tool changes, no alarms. Just like my other Fanuc machines.
    Thank you so much for taking time to help us, really appreciate it.
    Would you be able to share with us what that Keep Relay K4.5 did? Is this keep relay only specific to this particular machine?
    Hopefully this information can be useful for other people with similar machine.

    Also, for some reason on Cnczone it shows that you posted a reply, but when I open a thread that reply is missing. I had to go to your profile account, and read your recent forum posts to find "Yes that is the correct bit. Try changing it to 1 and see what happens."

    Thanks

    K 4.5 is only used on your machine. What the builder did was give you the option to ignore the alarm if you called a tool that was already in the spindle.

    The alarm code is a combination of "cycle start lamp" and "lamp 2" that blink. On the manual this alarm is referred as "tool command error" with the description "the tool in the spindle is designated. Designate another tool".
