Multiturn Absolute Encoder:

• 23-bit Resolution: Combines 8 million single-turn positions with 16-bit multiturn tracking (65,536 revolutions), enabling precise position tracking across extended rotations.
• Battery-Free Operation: Energy harvesting from motor rotation maintains multiturn data during power cycles.

Thermal Management:

• Integrated Cooling Fins: Improve heat dissipation, allowing sustained operation at peak torque.
• Thermal Monitoring: Built-in sensors prevent overheating during prolonged high-load use.

2. Performance Benchmarks

Torque and Speed:

• The 1.7 Nm continuous torque suits steady-state operations, while the 5.1 Nm peak torque enables rapid acceleration in applications like packaging machinery.
• At 6,000 rpm, it excels in high-speed tasks such as spindle drives or centrifugal separators.

Encoder Accuracy:

• Multiturn Resolution: Enables applications like rotary tables or wind turbine yaw systems, where tracking multiple revolutions is critical.
• Latency: <1 μs feedback update rate ensures real-time control in synchronized motion systems.

3. Applications

The ILM0702P02A0000 is tailored for:

• Rotary Indexing Tables: CNC machines, assembly lines, and food packaging systems requiring precise angular positioning.
• Wind Turbine Yaw Systems: Multiturn tracking ensures accurate blade orientation relative to wind direction.
• Medical Imaging: CT scanners and radiation therapy systems needing sub-degree precision over thousands of rotations.
• Automotive Testing: Dynamometers and engine test stands requiring repeatable positioning.
• Textile Machinery: Spinning frames and yarn winding systems with frequent start/stop cycles.

4. Technical Advantages

Energy Efficiency:

• Up to 94% efficiency reduces energy consumption, while regenerative braking function (when paired with an external brake) recovers kinetic energy.

Connectivity:

• EtherCAT FSoE: Enables safety communication over EtherCAT for integrated safety architectures.
• Dual-Port EtherCAT: Supports line topology for daisy-chained motion axes.

Precision and Safety:

• The 23-bit absolute encoder eliminates homing sequences, critical for CNC machining.
• Integrated Safe Torque Off (STO) and Safe Stop 1 (SS1) functions comply with ISO 13849-1.

5. Installation and Commissioning

Mounting:

• IEC B14 flange with a 14mm keyed shaft ensures secure coupling to mechanical loads.
• Adjustable mounting feet accommodate misalignment during installation.

Wiring:

• A single 48V DC supply powers the motor.
• Dedicated encoder feedback terminals (M12 connector) simplify integration with controllers.

Software Tools:

• Schneider Electric’s SoMove software streamlines parameter tuning, diagnostics, and firmware updates.
• Preloaded motion profiles (e.g., S-curve, trapezoidal) reduce programming effort.

6. Maintenance and Troubleshooting

Preventive Maintenance:

• The encoder’s self-diagnostics flag deviations in position accuracy.
• Regular inspection of cooling fins prevents thermal overload.

Error Handling:

• LED indicators on the motor housing provide real-time status feedback (e.g., overcurrent, overvoltage).
• Fault codes are logged internally for post-mortem analysis via SoMove.

7. Compatibility and Accessories

Optional Add-Ons:

• External Brake Kit: For applications requiring holding torque (e.g., vertical axes).
• Gearboxes: Planetary or helical options to increase torque density.
• Cables: Pre-terminated motor cables (1m, 2m, 5m lengths) with M12/M23 connectors.
• IP69K Connectors: For washdown environments in food processing.

Controller Compatibility:

• Works seamlessly with Schneider Electric’s PacDrive 3 and Modicon M580 PLCs.
• Third-party controller support via open-source EtherCAT stacks.

8. Environmental and Safety Compliance

• RoHS/REACH Compliance: Ensures absence of hazardous substances.
• Low Noise Emission: Operates at <72 dB(A), suitable for noise-sensitive environments.
• Safety Certifications: Meets ISO 13849-1 (PLd) and IEC 61800-5-2 for functional safety.

9. Ordering and Availability

As a Non-Stock item, the ILM0702P02A0000 requires a 4–6 week lead time from Schneider Electric’s manufacturing facilities. Customers are advised to:

• Confirm regional availability through Schneider Electric’s eCommerce portal or authorized distributors.
• Specify optional accessories (gearboxes, cables) during order placement to avoid delays.

10. Frequently Asked Questions (FAQs)

Q1: What is the difference between this model and the ILM0701P22A0000?
A1: The ILM0702P02A0000 offers 55% higher continuous torque (1.7 Nm vs. 1.1 Nm) and multiturn capability, making it suitable for heavier-duty applications.

Q2: Can this motor operate in a food-grade application?
A2: Yes, with an optional stainless steel shaft and IP69K-rated connectors for high-pressure washdown.

Q3: Is the multiturn encoder resolution upgradeable?
