Hi everyone I'm new to this site. Just would like to know if anyone could help. We bought a 2003 Mazak Multiplex 6200Y with a 640T Fusion control. We're trying to start the gantry and keep getting the alarm 748 (Not Zero Returned Axis Exist). Everything is at the home position. We don't know if we forget to fill in a parameter or a variable as this alarm is not in the manual. Any help would be much appreciated. Thank you
