Model Definition

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

• CG: Graphic & Communication (color graphic support).

• 02: Second hardware revision, with optimized layout, upgraded components, and improved noise immunity over CG01.

Technical Specifications

Electrical

• Power Supply: 24 V DC ±10%

• Processor: 32-bit graphic/communication MCU with faster rendering speed

• Interfaces: Color LCD/CRT video output, RS-232/485, Ethernet, and dedicated panel I/O

• Protocols: Ethernet TCP/IP, Modbus RTU, Yaskawa proprietary protocols

• EMC: Enhanced surge and electrostatic discharge protection for industrial environments

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 indoor control cabinets)

Core Functions

• Drives color LCD/CRT operator panels to display real-time machining data, axis coordinates, CNC programs, and alarm messages.

• Processes inputs from MDI keyboards, manual pulse generators, and function keys for full HMI operation.

• Enables high-speed, stable communication with host computers, PLCs, and peripheral devices.

• Offloads graphic rendering and data preprocessing from the main CPU, boosting system response efficiency.

• Provides real-time monitoring and diagnostic functions for operator panels and onboard circuits.

Application

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

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

• Legacy Yaskawa automation line maintenance; direct drop-in replacement for CG01 and older CG board revisions.

Compatibility & Notes

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

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

• Pin-compatible with CG01 but offers better color display performance and communication stability.

• Ensure cabinet ventilation and clean power supply to extend service life.
