    Default Fanuc control 11M for Makino machine

    I have a makino horizontal CNC machine with Fanuc control 11M problem.

    Alarm: B-axis access error.

    Please advice if anyone knows how to clear the alarm.

    Thanks.

    Dear .sir you can check maybe could be some machnical problem on the B-axis.

    I agree with Azri it could possibly be a mechnical problem. An excess error on a Fanuc control means that the drive is trying to move the axis and it is not moving the distance the control thinks it should. I have also seen coolant\oil cause this problem if it gets into the motor connectors.

    Could also be deviation between an encoder and scale if the B has a rotary scale installed which would be either contamination on the glass scale, a scratch, or bad cable.
