Does anyone knows how I can zero retun the atc magazine and sub arm of mori seiki sh 630? The machine crash and did not able to complete the atc moves that its supposed to do before tool change.

Call the Mori dealer. SH63/630 is not one you want to learn on. It also may need the fanuc handy if it's an older one. The sub arm is homed through the custom page, YOU CAN BREAK CAM BEARINGS IN THE ATC if you don't know what you are doing.
