Model Definition

• JANCD: Standard prefix for Yaskawa CNC/robot control PCBs.

• CG: Stands for Graphic & Communication.

• 01: Indicates the first hardware revision of the CG board, with optimized circuitry and component layout for better stability and compatibility.

Technical Specifications

Electrical

• Power Supply: 24 V DC ±10%

• Processor: 32-bit dedicated graphic/communication processor

• Ports: Dedicated interfaces for display (LCD/CRT), serial (RS-232/485), and I/O signals

• Protocols: Supports Ethernet, RS-232, RS-485 for industrial communication

Mechanical & Environmental

• Mounting: Standard slot installation in controller racks

• Dimensions: Approx. 220 mm × 180 mm × 30 mm

• Weight: 0.5–0.7 kg

• Operating Temperature: 0 °C to 45 °C

• Humidity: 10%–80% (non-condensing)

• Protection Class: IP20 (for industrial cabinets)

Core Functions

• Drives LCD/CRT operator panels to show real-time machining data, coordinates, programs, and alarms.

• Processes input from MDI keyboards, hand wheels, and function keys for full HMI.

• Enables high-speed communication with host computers, PLCs, and peripherals via Ethernet/serial ports.

• Offloads graphic rendering and data preprocessing from the main CPU to boost system efficiency.

• Monitors operation panel and circuit status in real time.

Application

• YASNAC J30/J50 CNC machine tools (lathes, mills, machining centers).

• Motoman XRC/NX100 robot controllers (welding, handling, assembly).

• Legacy Yaskawa automation line maintenance and retrofitting as a direct replacement for older CG board revisions.

Compatibility & Notes

• Compatible with backplanes: JANCD-B, JANCD-BB03, JANCD-BB50 (match controller model).

• Not interchangeable with main CPU or standard I/O boards.

• Drop-in replacement for compatible CG revisions (no extra wiring needed).

• Ensure cabinet ventilation and ambient temperature control for long-term reliability.
