Okuma Alarm A-1112 – Non-Functioning Device Detected
Alarm A-1112 indicates that the control system has detected a connected device that is not responding or not operating correctly.
The CNC recognizes a hardware unit, but it cannot communicate with it properly or retrieve valid operational data. In some cases, the installed software does not support the detected device configuration.
Possible causes include:
-
Hardware failure of the connected device
-
Communication interruption (cable, interface, I/O board)
-
Incorrect device configuration
-
Software version mismatch
-
Unsupported or newly installed component
This alarm prevents machine operation to avoid unsafe or undefined behavior.
Recommended actions:
-
Verify physical connections and wiring.
-
Check communication interfaces and I/O modules.
-
Confirm device configuration in parameters.
-
Ensure CNC software supports the installed hardware.
-
Restart the control system after inspection.
If the problem remains, hardware diagnostics of the affected unit is required.
