We have a Mori Seiki MV35/35. yasnac mx1 control
Here is the problem : It zeros out fine, jogs, manual is fine, no alarms.
If you command it in either MDI or Auto mode as soon as cycle start is pressed it just shows alm flashing on the bottom of the crt. No alarms on either the message or alarm page.It is the same for any m,s,t, or g code, it is same result. Only thing obvious is the contactor for the servos power supply drops out and diagnostic 1218.0 is high ( alm). We have done a regeneration of the memory, no difference. Any suggestions would be appreciated greatly.

Have you put your system switch back to #0 after the regeneration ?Have you tried a simple M03 or M04 in a line by itself without an axis move? I do know that Yasnac's were known to have issues when programming M,S, & T's in the same line of program. Made a habit not to do that. No alarms on screen, but do you have any alarms on the drive amplifiers or DCP unit or spindle drive?

The edit key turned on while in Memory (Auto) mode will cause this to happen.Check the key position.
