Description
Product Description
The YASKAWA PS-02 is a high-performance PLC module designed for industrial automation, specializing in motor control and system integration. Engineered for reliability, the PS-02 features advanced speed search technology that detects rotating motor shafts (e.g., coasting during power outages) to enable seamless restart without manual intervention. This capability reduces downtime and enhances operational efficiency in dynamic industrial environments. The YASKAWA PS-02 supports flexible connectivity with industrial networks, making it ideal for applications requiring precise motor control, real-time monitoring, and rapid system response.

YASKAWA PS-02
Advantages and Features
- Advanced Speed Search: Detects motor speed during coasting (e.g., power loss) and restarts directly without stopping, reducing downtime by up to 30%.
- Dual Detection Modes: Combines back EMF voltage estimation (for short power interruptions) and DC current injection (for complete power loss) for versatile operation.
- Rugged Design: Industrial-grade construction (IP20 protection) resists dust, vibrations, and temperature fluctuations.
- Flexible Integration: Supports modular I/O expansion and multiple communication protocols for seamless integration with HMIs, SCADA systems, and IoT platforms.
- User-Friendly Programming: Intuitive configuration via YASKAWA’s PLC software suite, minimizing commissioning time.
Application Areas and Case Studies
- Manufacturing: Conveyor systems, pumps, and fan control in automotive and food processing plants.
- Energy: Power generation auxiliary systems and renewable energy installations.
- Utilities: Water treatment facilities and HVAC automation.
Case Study: A European water treatment plant used the YASKAWA PS-02 to automate pump control. The module’s speed search feature reduced restart delays by 25%, ensuring continuous operation during grid fluctuations and improving system reliability.
Competitive Comparison
Compared to standard PLC modules, the PS-02 offers a built-in speed search function (eliminating the need for external sensors) and dual detection modes, reducing hardware costs by 15%. Its compact design (2 kg) and wide temperature range (-10°C to 55°C) outperform competitors in harsh industrial settings.

Selection Recommendations
- Compatibility: Ensure compatibility with existing YASKAWA drives (e.g., V1000 series) or third-party systems.
- Environment: Opt for IP20-rated models for indoor use; consider ruggedized versions for outdoor/harsh environments.
- Functionality: Prioritize speed search requirements (e.g., frequent power interruptions) to leverage the module’s core feature.
Precautions
- Installation: Follow DIN rail mounting guidelines and ensure proper grounding to prevent EMI interference.
- Maintenance: Regularly inspect connectors; replace backup batteries (if applicable) every 5 years.
- Safety: Adhere to IEC 61131-5 safety standards for motor control systems.
- Startup: Perform no-load testing (as per manual) before full operation to verify speed search accuracy.
Conclusion
The YASKAWA PS-02 excels in applications requiring reliable motor control and rapid system recovery. Its innovative speed search technology, rugged design, and flexible integration make it a versatile choice for industrial automation.
