You know what the "TS" stands for, right? How well does it work before you run this program? When you try jogging each axis, does it respond well? When you ask it to move 100mm, for instance, does it do that?

What happens when you go into the MDI (Manual Data Input) screen and give it a command like G01 X25 F30 ? Does it hit the limit switches? If so, try giving it a G21 command to switch it from inches to mm. If it goes 25 mm and stops, then you've got some other problem with your G-code.
