3. Core Functions

3.1 LCD Driving and System Display

Drives the XRC controller’s front-panel LCD to present critical system information in real time, including robot operating mode (Auto/Manual/Teach), servo on/off status, alarm and error codes with descriptive messages, program execution status, input/output (I/O) port states, and system parameter configurations.

3.2 Local Operation and Control

Processes input signals from the controller’s physical pushbuttons to enable essential on-site operations, such as mode selection switching, program start, stop, and pause, alarm reset and fault acknowledgment, emergency stop (E-stop) status monitoring, and manual jog control for robot positioning.

3.3 Status Indication via Onboard LEDs

Features multiple integrated LED indicators to provide at-a-glance system status, including power supply presence, normal system operation, active alarms or faults, data communication activity between the board and main CPU, and servo system readiness.

3.4 Internal System Communication

Acts as a communication bridge between the user interface and the XRC controller’s main CPU. Transmits user input commands from buttons and switches to the main system, and receives display data and status updates from the main CPU to output to the LCD and LEDs.

4. Compatibility and Installation Instructions

4.1 Compatibility

This board is exclusively compatible with Motoman XRC series robot controllers. It is not compatible with other Yaskawa robot controller series, including NX100, NXC100, DX100, DX200, or with Yasnac CNC systems.

4.2 Installation Steps

  1. Power off the XRC controller completely and wait for a minimum of 5 minutes to allow internal capacitors to fully discharge, preventing electrical shock or component damage.

  2. Wear an ESD (Electrostatic Discharge) wristband connected to a grounded metal surface to avoid static electricity damage to sensitive electronic components on the board.

  3. Locate the dedicated slot on the controller’s backplane for the LCD/interface board. Insert JANCD-SP05 firmly into the slot, ensuring the edge connectors are fully seated.

  4. Secure the board in place with the mounting screws provided with the controller.

  5. Connect the LCD module cable to the dedicated LCD port on the board, then connect the button/LED harness to the corresponding control interface.

  6. Restore power to the controller and verify normal operation: check that the LCD initializes correctly, all power/status LEDs light as expected, and front-panel buttons respond to input.


5. Maintenance and Safety Precautions

5.1 Regular Maintenance

Perform a comprehensive inspection every 3 months. Check all cables and connectors attached to the board for looseness, dust accumulation, or signs of oxidation. Inspect the board surface for dirt, debris, or physical damage.

5.2 Cleaning Guidelines

Use only a dry, lint-free cloth to clean the board and connected components. Do not use liquid detergents, solvents, or compressed air, as these can damage electronic components or leave conductive residues.

5.3 Static Electricity Protection

Always wear an ESD wristband and work in a static-controlled environment when handling the board. Static discharge can permanently damage integrated circuits and other sensitive parts.

5.4 Power Safety

Disconnect all power sources to the controller before performing any disassembly, inspection, or maintenance work on the board. Never work on live equipment.

5.5 Qualified Personnel

All installation, maintenance, and repair procedures must be performed by trained and qualified professional technicians with knowledge of Yaskawa Motoman robot systems.

6. Troubleshooting Guidance

6.1 LCD Screen No Display

This issue may result from a loose or damaged LCD cable, poor connection between the board and backplane, or a faulty LCD module. Ensure the controller is powered off, then check and reseat all cables and the board itself. If the problem persists, inspect the LCD module for damage.

6.2 Front-Panel Buttons Unresponsive

Unresponsive buttons are often caused by a disconnected or damaged button harness, faulty wiring, or a malfunctioning button circuit on the board. Power off the controller, verify the harness connections, and check for broken wires or signs of short circuits.

6.3 All Onboard LEDs Remain Off

A complete loss of LED indication typically indicates an abnormal 5 VDC power supply from the controller backplane or a failed power circuit on the board. Check the backplane power output and inspect the board’s power connector and circuitry for damage.

6.4 System Fails to Recognize the Board

If the XRC main CPU does not detect JANCD-SP05, the board may be improperly inserted, edge connectors may be dirty or oxidized, or the internal communication bus may be faulty. Power off the controller, remove and reinstall the board, and clean the edge connectors with a dry, lint-free cloth.
