Okuma Alarm P-0728 – FL-net Error

Okuma Alarm P-0728 indicates that an error occurred during startup of the FL-net communication card. This card is used for network communication between the CNC control and external systems. If the control cannot properly initialize the FL-net card during startup, the machine generates this alarm. Restarting the machine may sometimes clear the error, but if it appears again the FL-net card or communication system may need inspection.
