    Question Servo problem after battery change

    Hello,

    I really hope that you can help me.
    We are using CNC Brother TC-31A, after the "Low battery" icon appeared, we have replaced the batteries with new ones, but then a new error appeared:
    5066. 17 **M SERVO (BATT DROP)


    Below I've written all info found in operation manual on the 5066 error message
    Error message: M SERVO (***)
    Stop level 5: The servo system stops
    Reset level 3: Turn OFF the power. (An alarm cannot be reset otherwise)
    Cause: A servo error has occurred for the M axis. The cause differs depending on (***). Refer to the servo error list.

    SERVO ERROR MESSAGE
    Display: BATT DROP
    Cause: Battery voltage drop
    Solution: Replace alkaline battery for absolute encoder backup


    Already tried multiple times to turn off the CNC, put the old batteries back, but nothing helps.
    Have no idea how to fix that, it seems like no information is available via internet, that is why I think your experience could be appreciated very highly.


    Thank you in advance,
    Artur

    I've got a reply to the question elsewhere, decided to post it here also, just in case anyone else is searching for the solution.


    Good afternoon Mr. Andrejev

    I guess the voltage of the backup batteries was cut for longer than 20-30 minutes.
    In this case the machine 'forgot' the magazine position and you need to set it again.

    - After clearing the start point data, move the magazine position nr.1 to the tool change area and clear the start point once again.

    - Finally disable the ATC maintenance mode (I/O), (1), (Enter), (page up) set 0 for (ATC maintenance mode) and power the machine off and on again.

    - If everything went well you can start to work with the machine as usual.
