Key Functions

  1. Power Conversion: Converts industrial AC to clean, regulated 5 V/24 V DC for the controller.

  2. System Power Distribution: Supplies stable power to main CPU, motion boards, I/O, and communication modules.

  3. Fault Protection: Automatically shuts down and triggers an alarm under overload or short‑circuit conditions.

  4. Noise Suppression: Filters voltage spikes and EMI to ensure system stability.

  5. Modular Redundancy: Supports hot‑swap replacement in critical applications.

Applications

  • Yasnac XRC Robot Controllers: Welding, handling, assembly, and painting robots.

  • Yasnac i80 CNC Machines: Machining centers, lathes, and multi‑axis machine tools.

  • Retrofit & Replacement: Maintenance projects for aging Yaskawa automation systems.

  • Industrial Automation Lines: High‑reliability power for motion‑control equipment.

Installation & Maintenance

  • Use ESD protection when handling to avoid static damage.

  • Verify AC input voltage is within 200–230 V range before powering on.

  • Check LED indicators (PWR, OK, ALM) for normal operation.

  • Clean dust from the heat sink and vents every 6 months.

  • Ensure adequate cabinet ventilation (avoid overheating).

  • Back up system parameters before replacing the module.
