6. Selection Recommendations
- Power Requirements: Match output current (18 A) to system load (e.g., 3–5 servo axes).
- Environment: Choose IP54 variants for wet/dusty environments (e.g., food processing).
- Redundancy: Pair with Yaskawa’s CPS-RED series for dual-power configurations in critical systems (e.g., medical device manufacturing).
- Budget: Base model ($500–$700) suits standard applications; redundant systems start at $1,200.
7. Installation and Maintenance Notes
- Safety: Follow IEC 61558-2-16 safety standards; ensure proper grounding (PE terminal).
- Cooling: Maintain airflow (200–500 LFM) to prevent overheating; avoid ambient temperatures >55°C.
- Wiring: Use 4–6 mm² cables for input/output; torque terminals to 4 N·m.
- Maintenance: Inspect capacitors annually; replace every 5–7 years (depending on duty cycle).
