Okuma Alarm A-1113 – MCS Parameter Learning Error
Alarm-A 1113 on Okuma CNC machines indicates a problem during the MCS parameter learning process.
This alarm appears when the control system fails to correctly complete the correction parameter learning procedure.
The MCS (Machine Coordinate System) learning process is used to determine the correct reference positions and correction values for the machine axes. If this process is interrupted or parameters cannot be stored correctly, the control generates Alarm A-1113.
Possible causes
Several issues may trigger this alarm:
-
Incorrect or incomplete MCS parameter learning procedure
-
Axis reference position errors
-
Servo system or encoder signal problems
-
Incorrect parameter settings in the control system
-
Communication issues between control and servo drives
-
Power interruption during parameter learning
What happens when this alarm appears
When Alarm-A 1113 occurs, the CNC control cannot complete the parameter correction process.
As a result, the machine may refuse to move certain axes or prevent normal operation until the problem is resolved.
Recommended actions
To resolve this alarm, the following steps are usually required:
-
Restart the CNC control and check if the alarm reappears.
-
Verify that the machine reference return procedure has been completed correctly.
-
Repeat the MCS parameter learning procedure according to the Okuma service manual.
-
Check encoder signals and servo drive status.
-
Verify that no parameters were corrupted or incorrectly modified.
If the alarm continues to appear, the issue may require professional diagnostics of the CNC control system or servo electronics.
