Okuma Alarm B-2362 – Nose-R Compensation Cancel (G40) Only Allowed in G00 or G01

Okuma Alarm B-2362 indicates that tool nose radius compensation cancel (G40) has been commanded outside of the allowed motion modes. This operation is only permitted during G00 (rapid) or G01 (linear feed) movements.

Meaning of the Alarm

This alarm occurs when the control system detects that the G40 command is executed in an unsupported mode. Tool nose radius compensation can only be canceled while the machine is operating in G00 or G01.

Possible Causes

  • G40 command used outside G00 or G01 mode

  • Incorrect CNC program sequence

  • Compensation cancel applied during unsupported motion type

  • Programming error in toolpath

  • Incorrect machining cycle configuration

Recommended Checks

  • Verify that G40 is executed only in G00 or G01 mode

  • Review CNC program sequence around compensation commands

  • Ensure correct order of G-code instructions

  • Check toolpath logic and machining cycle setup

  • Test program execution step-by-step

When Professional Service Is Required

If the alarm persists after correcting the program, the issue may involve control system behavior or deeper configuration problems. In such cases, professional diagnostics are recommended.
