Fanuc oiTC X Axis Running in Negative

Hi to you all, I am running a Colchester 2005 Multiturn Lathe with a Fanuc oiTC control and a strange thing has started happening. All the X dimensions I program are being executed in the Negative (-X) instead of the positive. I have checked my program and its fine. The Z axis seems to be working as programmed but can't understand what is happening in X

Any help would be welcome.

Thanks
