Final answer:
Either the Feedhold button or the Emergency button can be pressed to stop the axes of machines during program run, but the ability to continue from the same line depends on the machine control system.
Step-by-step explanation:
In the context of machine controls, either the Feedhold button or the Emergency button can be pressed to stop the axes of machines during program run. However, the continuation of the program from the same line it was stopped depends on the specific machine control system being used.
Some machine control systems allow the program to be resumed from the same line, while others may require additional steps or adjustments before the program can continue.
It is important to consult the machine's documentation or seek guidance from a qualified technician to understand the specific behavior of the machine control system in use.
