Anyone have experience with this error code?

Manual says:
"Servo enable travel axis"
The axis-specific servo enable signal was removed by the PLC user program during traversing"
"Inhibiting of NC START"

What does this mean? What do i look for?
I think the "2" in 1682 is the axis which in this case i think would be my Z axis. 0=X, 1=Y, 2=Z, 3=W but this is a guess.

My router crashed twice on the same Z move with this error while cutting wood but would not repeat the error dry running.

Stuck with holes in my spoil boards....

Thank you.
