Good day.
The "OT113 CPU ERROR" appears when machine is turned on. Can't find any notice about this error in manual.
Best regards.

No manual here either but maybe:
Check DC power-supply.
Re-seat boards, check all connectors at controller.
Any LED's lit RED on controller?

OT 113 CPU ERROR:
The CPU or a peripheral circuit of the speed control unit of the
spindle motor is faulty.

Yep, fanuc spindle converter gives the message "AL-17". But I see 15 error messages in the manual only. When I push four buttons ("mode", "data set", ->,<-) message disappeares. We bought the lathe recently. What could happend?

My notes say Alarm 17:
(1) Meaning
In the main circuit, the voltage at the DC link is abnormally high.
A fuse of the AC reactor unit may have blown.
(2) Cause and troubleshooting
(a) An input fuse of the AC reactor unit has blown.
→ Replace the fuse.
(b) Regeneration circuit failure
→ Replace the unit.

Thanks. To my mind there are some problems with capacities. Couse this alarm appears in the morning (temperature changes).
