1. Design Innovation: Multiturn Encoder and Keyed Shaft
The ILM0701P12A0000 stands out 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.
14mm Keyed Shaft:
- Torque Transmission: The keyed design eliminates backlash, critical for applications like conveyor systems or robotic arms.
- Interchangeability: Compatible with industry-standard couplings and gearboxes.
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 ILM0701P12A0000 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.
Connectivity:
- EtherCAT FSoE: Enables safety communication over EtherCAT for integrated safety architectures.
- Dual-Port EtherCAT: Supports line topology for daisy-chained motion axes.
Energy Efficiency:
- Up to 95% efficiency reduces energy consumption, while regenerative braking function (when paired with an external brake) recovers kinetic energy.
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 (if forced air is used) 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 <70 dB(A), suitable for noise-sensitive environments.
- Safety Functions: Supports STO (Safe Torque Off) and SS1 (Safe Stop 1) per ISO 13849-1.
9. Ordering and Availability
As a Non-Stock item, the ILM0701P12A0000 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.

10. Frequently Asked Questions (FAQs)
Q1: What is the difference between single-turn and multiturn encoders?
A1: Single-turn encoders track positions within one revolution, while multiturn encoders track thousands of revolutions, critical for rotary tables or wind turbines.
Q2: Can this motor operate in a food-grade application?
A1: Yes, but an optional stainless steel shaft and IP69K-rated connectors are recommended.
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 I use this motor for vertical applications without a brake?
A4: Yes, but an external brake is recommended to prevent backdriving in case of power failure.
Conclusion
The Schneider Electric Lexium 62 ILM0701P12A0000 integrated servo motor redefines precision and efficiency in motion control. Its combination of a multiturn absolute encoder, keyed shaft, 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 torque transmission, the ILM0701P12A0000 sets a new benchmark in its class.
