Okuma Alarm B-2969 – G23 Feed Command Is Zero

Okuma Alarm B-2969 indicates that the feedrate value (F) assigned to the G23 command is set to zero. This prevents the machine from executing the operation correctly.

Meaning of the Alarm

This alarm occurs when the control system detects that the feed command (F) in a G23 operation is zero or missing. Since feedrate is required for movement, the machine cannot proceed with the operation.

Possible Causes

  • Feedrate value (F) not specified in the program

  • Feedrate set to zero

  • Incorrect CNC program configuration

  • Programming error in G23 command

  • Missing parameter in machining cycle

Recommended Checks

  • Verify that a valid feedrate (F value) is defined

  • Ensure feedrate is greater than zero

  • Review CNC program around the G23 command

  • Check machining cycle parameters

  • Test program execution step-by-step

When Professional Service Is Required

If the alarm persists after correcting the feedrate values, the issue may be related to control system configuration or program logic. In such cases, professional diagnostics are recommended.
