Okuma Alarm B-2957 – G22 Feed Command Is Zero
Okuma Alarm B-2957 indicates that the feedrate value (F) assigned to the G22 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) for a G22 operation is zero or not properly defined. Since feedrate is required for movement, the machine cannot proceed.
Possible Causes
-
Feedrate value (F) not specified
-
Feedrate set to zero
-
Incorrect CNC program configuration
-
Programming error in G22 command
-
Missing or invalid parameter
Recommended Checks
-
Verify that a valid feedrate (F value) is defined
-
Ensure feedrate is greater than zero
-
Review CNC program around the G22 command
-
Check machining parameters
-
Test program execution step-by-step
When Professional Service Is Required
If the alarm persists after correcting feedrate values, the issue may be related to control system configuration or deeper program logic errors. In such cases, professional diagnostics are recommended.
