JANCD-CP50B (Yaskawa Yasnac J50 CNC Main CPU Board)

JANCD-CP50B is the revised B-version main CPU board for the Yaskawa Yasnac J50 series CNC controller, serving as the core motion and system controller for machine tools and automation systems. It is an upgraded iteration of the original JANCD-CP50, with enhanced components and reliability. Now discontinued by Yaskawa; only new surplus, refurbished, and used units are available for maintenance and replacement.

Description

Basic Specifications

  • Manufacturer: Yaskawa Electric (Yasnac)

  • Model: JANCD-CP50B (J50 MAIN CPU Board)

  • Type: CNC Main CPU / Motion Control PCB

  • Compatible System: Exclusively for Yasnac J50 CNC (not interchangeable with CP50, CP11, or other CP-series boards)

  • Processor: 32-bit industrial CPU

  • Max. Control Axes: Up to 16 axes synchronous motion

  • Interpolation Speed: 0.05 ms per command (high-speed processing)

  • Power Supply: 24 V DC

  • Operating Temperature: 0 °C ~ 45 °C (industrial standard)

  • Condition: New surplus, refurbished, used

  • Warranty: 12 months (seller-dependent)

Key Features (vs. CP50)

  1. B-Revision Upgrade: Improved voltage regulation, more stable memory modules, and better solder joints for extended service life.

  2. 16-Axis High-Speed Motion: Supports linear/circular interpolation, electronic cam, and multi-axis synchronization for complex machine tools.

  3. Enhanced I/O & Communication:

    • Onboard Profibus-DP, CAN, Modbus; connects up to 126 Profibus slaves.

    • Faster 32-bit data bus (100 MB/s) for high-speed data exchange.

  4. Industrial-Grade Durability: Vibration-resistant, EMI-shielded PCB for factory environments; built-in self-diagnostics and fault logging.

  5. Direct Replacement: Plug-and-play for J50 CNC racks; no complex configuration needed when replacing CP50B or original CP50.

Core Functions

  1. Execute CNC G-code programs and calculate real-time motion trajectories.

  2. Control servo drives/spindles with high-precision linear/circular interpolation.

  3. Manage I/O signals and communication with HMI, panels, and peripherals.

  4. Store system parameters, user programs, and tool offsets.

  5. Provide self-diagnostics and error logging for fast troubleshooting.

Compatibility & Notes

  • CP50 vs. CP50B: CP50B is the revised B-version of CP50; functionally identical but with upgraded hardware for better reliability.

  • Not Interchangeable: Cannot replace CP11 (ERC robots) or later CP-series boards (different pinout, dimensions, architecture).

  • Legacy Use Only: Exclusively for Yasnac J50 CNC (pre-LX1 platform); original production discontinued, limited stock available.
