12330

Write file failed

Fanuc · R-30iA R-30iB Controller

What does 12330 mean?

A general failure occurred during a file write operation. This IO_STATUS error suggests an underlying issue that prevented data from being successfully written to the file associated with the file_id. The program will abort if the file_id is invalid.

Common Causes

  • The target storage device (e.g., floppy disk, memory card) may be full or inaccessible.
  • A low-level I/O error occurred on the file system during the write process, indicating hardware or media issues.
  • The file_id used does not correspond to a valid opened file, leading to an invalid write target.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Verify the target storage device has sufficient free space to accommodate the data being written.

  2. 2

    Confirm the file_id corresponds to a properly opened file and that the device is mounted and accessible.

  3. 3

    Use the KAREL command READ file_id(cr) to clear any existing IO_STATUS error condition.
