Accidently deleted my tool change program. Was having issues loading a program but in the process of straightening that out I lost my O9020 program. I can load a program into the machine but when I try and load the O9020 program back in it throws an 074 ps alarm (program does not fall within the rang of program numbers of 0-9999, modify the number and try again). Any ideas on this? Any help would greatly be appreciated.
