How to Find Rapid Dial Address on a Fanuc CNC.

1 Prepare the Machine & Work Area

1. Safe state – Put the machine in MDI or “zero-feed” mode, spindle stopped, and ensure no axes will move when you twist the dial.

2. Visual access – Swing the control so the screen and dial are in one frame when you shoot video.

3. Phone ready – Open the camera app in landscape; set focus/brightness so both the screen text and dial are legible.

2 Open the PMC Diagnosis Page

1. Press SYSTEM on the control panel.

2. Cursor-right to PMC (the soft key may read PMC or PMCG).

3. Choose DIAGNOS (Diagnosis) ➜ you’re now in the I/O monitor where X-addresses (inputs) and Y-addresses (outputs) are displayed in real time.

3 Locate the Override Dial’s X-Address

1. Press SEARCH (or F SEARCH) and type X0, then EXECUTE – this jumps to the start of the X-input range.

2. Rotate the rapid/feed-override dial slowly through its detents (0 → 25 → 50 → 75 → 100 %).

3. Watch for any bits that flip from 0 to 1 (or vice-versa) exactly when the dial moves.

4. When you spot changing bits, note the full address (e.g., X010 on a 16-bit page or X10 on an 8-bit page).

   • If more than one address changes, stop the dial at each detent and see which address gives a consistent binary pattern unique to each position.

5. Confirm the candidate address by rotating back and forth; only that X-word should toggle with the dial.

4 Map Each Dial Position

(The pattern above is an example; record the real bits you see.)

1. For each detent, pause long enough for the screen to refresh (about 1 s).

2. Jot down the exact bit pattern or decimal value.

5 Shoot the Verification Video

1. Frame both the dial and the screen so the X-address row is readable.

2. Start recording.

3. Beginning at 0 %, rotate the dial through every detent up to 100 % and back to 0 %.

4. Announce out loud the value you see (e.g., “X10 equals 00000010 – that’s 50 percent”).

5. Stop recording (≈ 30–40 s total).

6 Send the Results to MachineMetrics

• Share the video file (email, Teams, or upload link).

• Include your mapping table and the confirmed X-address (e.g., X10).

• We’ll use this to configure MachineMetrics so the dashboard shows the correct feed-override percentage.
