Tool Compensation Mode

I ran a program in our CNC and i got this error saying "CH 0 Profile radius Less Tool Radius" i have a arc that is .125" and my tool DIA at .123". I've changed the tool dia to be less and also being the exact size of the arc and i still get the same issue. My G code is saying i have the tool compensation mode as "false". How do i turn on the tool compensation mode?
