1. Design Innovation: Multiturn Encoder and Brake Integration
The ILM0701P02F0000 distinguishes itself through two critical features:
Multiturn Absolute Encoder:
- 23-bit Resolution: Combines 8,388,608 single-turn positions with 16-bit multiturn tracking (65,536 revolutions), enabling precise position tracking across extended rotations.
- Battery-Free Operation: Utilizes energy harvesting from motor rotation to maintain multiturn data during power cycles, eliminating the need for backup batteries.
Failsafe Brake System:
- Spring-Applied Design: Engages automatically during power failures to prevent uncontrolled motion.
- Dynamic Braking: Supports controlled deceleration via regenerative energy dissipation (requires external resistor for high-inertia loads).
2. Performance Benchmarks
Torque and Speed:
- The 1.1 Nm continuous torque suits steady-state operations, while the 3.3 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 ILM0701P02F0000 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.
- Printing Presses: Web tension control and registration adjustments in high-speed printers.
- Automotive Testing: Dynamometers and engine test stands requiring repeatable positioning.
4. Technical Advantages
Multiturn Capability:
- Eliminates homing sequences after power cycles, reducing downtime in applications like robotic welding cells.
- Battery-free operation lowers maintenance costs and environmental impact.
Safety Integration:
- SIL 2 Certification: Compliance with IEC 61508 for functional safety in critical processes.
- Safe Operating Stop (SOS): Initiates controlled deceleration to a standstill during emergencies.
Connectivity:
- EtherCAT FSoE: Enables safety communication over EtherCAT for integrated safety architectures.
- Dual-Port EtherCAT: Supports line topology for daisy-chained motion axes.
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 both the motor and brake.
- Dedicated brake control terminals (M12 connector) simplify integration with safety PLCs.
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 brake wear indicators prevents unexpected failures.
Error Handling:
- LED indicators on the motor housing provide real-time status feedback (e.g., brake fault, overcurrent).
- Fault codes are logged internally for post-mortem analysis via SoMove.
7. Compatibility and Accessories
Optional Add-Ons:
- Gearboxes: Planetary or helical options to increase torque density.

9. Ordering and Availability
As a Non-Stock item, the ILM0701P02F0000 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 single-turn and multiturn encoders?
A1: Single-turn encoders (e.g., ILM0701P01F0000) track positions within one revolution, while multiturn encoders (ILM0701P02F0000) track thousands of revolutions, critical for rotary tables or wind turbines.
Q2: Can the brake hold the motor in case of a power failure?
A1: Yes, the spring-applied brake engages automatically, providing 5 Nm static holding torque.
Q3: Is the multiturn encoder resolution upgradeable?
A3: No, the 23-bit resolution is fixed. For higher precision, consider the ILM1202 model (24-bit).
Q4: Can this motor operate in a food-grade application?
A4: Yes, but an optional stainless steel shaft and IP69K-rated connectors are recommended.
Conclusion
The Schneider Electric Lexium 62 ILM0701P02F0000 integrated servo motor redefines precision and safety in motion control. Its combination of a multiturn absolute encoder, failsafe brake, and 1.1 Nm torque makes it indispensable for applications requiring sub-degree accuracy over extended rotations. While its Non-Stock status reflects its specialized nature, the 4–6 week lead time is justified by the motor’s advanced capabilities and Schneider Electric’s rigorous quality control. For engineers seeking a compact, high-performance servo solution with multiturn tracking and safety integration, the ILM0701P02F0000 sets a new benchmark in its class.
