I've been running a Mori SL25 with the 15-T and FAPT for 14 years and it has 2 soft keys that I've never found a use for, I don't have a book for the control and I was just wondering what they are used for, 1 is on the Position page and the key is "MEM_FRP" and the other is on the Tool Offset page and it says "WORK_COORD", can someone enlighten me?
