Model Definition

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

• CG: Graphic & Communication.

• 01: First hardware revision of the CG platform.

• C: Enhanced version with improved communication robustness, wider voltage tolerance, and better environmental adaptability.

Technical Specifications

Electrical

• Power Supply: 24 V DC ±15% (wider than CG01)

• Processor: 32-bit graphic/communication MCU with enhanced error handling

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

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

• EMC: Improved surge and noise immunity for harsh industrial environments

Mechanical & Environmental

• Mounting: Standard slot mount in controller racks

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

• Weight: 0.5–0.7 kg

• Operating Temperature: 0 °C to 50 °C (extended upper limit)

• Humidity: 10%–85% (non-condensing)

• Protection Class: IP20 (for indoor control cabinets)

Core Functions

• Drives LCD/CRT operator panels, showing real-time machining data, axis positions, programs, and alarms.

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

• Provides high-speed, noise-resistant communication with host computers, PLCs, and peripherals.

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

• Monitors panel and circuit status with enhanced diagnostic features for easier maintenance.

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 boards.

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.

• “C” version is pin-compatible with CG01 but offers better stability in high-noise, high-temperature environments.

• Ensure cabinet ventilation and clean power supply for long-term reliability.
