Okuma Alarm B-2543 – Turret Index Error Position

Okuma Alarm B-2543 indicates that an axis feed command was issued while the turret was in an incorrect index position. This means the machine control detected that the turret had not properly completed its indexing cycle or was not locked in the correct tool position when a movement command was given. Because the turret must be fully indexed and locked before axis movement can occur, the control stops the machine and generates this alarm to prevent tool collision or mechanical damage. The problem can occur due to incomplete turret indexing, sensor or position detection issues, mechanical problems in the turret mechanism, or control timing errors. Restarting the machine and ensuring the turret completes its indexing cycle may sometimes resolve the issue, but if the alarm continues the turret indexing system or related components may need inspection.
