Model Definition

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

• C: Core CPU / Central Control (main processing unit)

• P/G (suffix):

  • CP: CPU Board (main processor)

  • CG: Graphic/Communication CPU Board

• 01/02/50: Hardware revision or platform designation

Specifications (Typical for JANCD-C series)

Electrical

• Power: 24 V DC ±10%

• Processor: 32-bit industrial CPU

• Memory: 4–16 MB DRAM, 2–8 MB Flash

• Bus: High-speed backplane bus (XRC/NX100/J50)

Mechanical & Environmental

• Dimensions: 170 × 100 × 30 mm

• Weight: 0.2–0.4 kg

• Mounting: Rack slot mount (controller main rack)

• Operating Temp: 0 °C to +50 °C

• Humidity: 10%–80% RH, non-condensing

Key Functions

• System Core: Executes robot/CNC programs, motion control logic, and system management.

• Motion Control: Calculates servo commands for axes (robot joints/CNC axes).

• Data Processing: Handles I/O signals, communication protocols, and fault diagnostics.

• Communication: Connects to teach pendants, HMIs, PLCs, and networks (Ethernet/RS-232).

• System Supervision: Monitors hardware status, ensures safety interlocks, and manages system startup/shutdown.

Common Variants & Applications

Compatibility & Notes

• Dedicated to Yaskawa controllers: Not interchangeable with non-JANCD boards.

• Backplane dependency: Works with JANCD-B (XRC) / JANCD-BB03 (NX100) / JANCD-BB50 (J50) backplanes.

• Critical spare part: Failure causes controller boot failure or system alarms.
