Hello, a new member here. We just started to have a problem with one of our Mori Seiki that's been in use for over 9 years now. We did take it out of service for a short time when we got new replacement machines, but had to put it back in service when one of our Okuma machines went down. It was running fine for quite a while, but it is just now showing the message EX 0357 Turret Index Time out. The program starts ok, does the rough passes, but when it indexes the new tool for the final pass, the message appears. Our lead operator also found these alarm messages in the history:

749 S-spindle LSI Error
500 Overtravel +Z (2 times)
400 Servo Alarm - X axis overload
414 Servo Alarm - Z axis detected Error
751 Spindle - 1 Alarm Detect (3 times)
414 Servo Alarm - X axis detect
750 Spindle Serial Link Error (3 times)
501 Over Travel -X

The serial link error may have been caused when I was checking the cables in the back. Any help would be greatly appreciated. Thank-you.
