3. Main Functions

3.1 LCD Drive & System Display

Drives the XRC front‑panel LCD to show robot operating mode (Auto/Manual/Teach), servo status, alarm/error codes and messages, program status, I/O states, and system parameters.

3.2 Operator Panel Input Handling

Scans and debounces front‑panel pushbuttons and mode switches; sends key codes and mode signals to the main CPU for local operation including start/stop, jog, alarm reset, and E‑stop acknowledgment.

3.3 Status LED Indication

Onboard and front‑panel LEDs indicate power, system run, alarm/fault, communication activity, and servo ready status for quick visual diagnosis.

3.4 Communication with Main CPU

Transmits operator input to the XRC main CPU and receives display data and status updates to drive the LCD and LEDs; supports real‑time HMI refresh.

4. Compatibility & Installation

4.1 Compatibility

Exclusively for Motoman XRC controllers. Not compatible with NX100, NXC100, DX series, or Yasnac CNC systems.

4.2 Installation Steps

  1. Power off the controller and wait ≥5 minutes for capacitor discharge.

  2. Use an ESD wristband connected to ground.

  3. Insert JANCD-SP17 into the designated XRC backplane slot; seat firmly.

  4. Secure with mounting screws.

  5. Connect LCD cable and keypad/LED harness to the board connectors.

  6. Power on and verify LCD initialization, LED states, and button responsiveness.


5. Maintenance & Safety

5.1 Maintenance

Inspect every 3 months: check cables/connectors for looseness, dust, or oxidation; clean board surface with a dry lint‑free cloth only.

5.2 ESD Safety

Always ground yourself when handling the board to avoid static damage to ICs.

5.3 Power Safety

Disconnect all power before removal, inspection, or maintenance.

5.4 Qualified Personnel

Installation and service must be performed by trained technicians familiar with Motoman XRC systems.

6. Troubleshooting

6.1 LCD No Display

Possible causes include loose LCD cable, poor backplane connection, or faulty LCD module. Power off, reseat cables and board; check LCD module if issue persists.

6.2 Keys/Panel Unresponsive

Check keypad harness connection, wiring continuity, and switch integrity; inspect for shorts or damaged traces on the board.

6.3 All LEDs Off

Verify 5 VDC supply from backplane; check power connector and onboard power circuitry for damage.

6.4 Board Not Recognized

Reseat the board; clean edge connectors with dry cloth; inspect backplane slot and communication bus.
