Hello
I am new to the forum, I have a problem with the machine DRIMILL CENTER KN 30 HS KIRA FANUC control, the problem is that it does not run the tool change
Alarms are following:

-X overtravel 511
-Y overtravel 521
-Z overtravel 531

Running the code M86, after running the code and manually placed for tool change, marking the following warning:

X overtravel
Y overtravel
Z overtravel

and the second LED (red LED) to the power source in NC is turn on .

Review the settings

700 00000100
701 00000100
702 00000100
704 -00400100
705 -00300100
706 -00250100

and change for:

700 99999999
701 99999999
702 99999999
704 -99999999
705 -99999999
706 -99999999

and still does not change the tool overtravel alarms.
**

MST function complete signal failure is not returned in the specified period after M. S. T. instruction has been executed.

how to save the position of the tool change point? or how executing change tool?

Help please!
