• Large keyed shaft (35 mm) with 10 mm key for robust mechanical coupling and torque transmission.
• High radial and axial load ratings (Fr 1470 N, Fa 490 N) support demanding mechanical linkages.
• Natural convection cooling and IP40 protection suitable for protected industrial environments.

Typical applications

• Heavy‑duty robotics, gantry and CNC axes
• Packaging, printing and high‑throughput material‑handling systems
• Indexing tables, rotary actuators and OEM automation requiring high torque and precision
• Systems using Lexium 23 Plus drive family (verify compatibility per datasheet)

Installation and service notes

• Verify mechanical and electrical compatibility (mounting flange, connector pinout, drive compatibility) prior to installation.
• This unit is discontinued (Discontinued 23‑Jan‑2021; EOS 31‑Dec‑2023). Plan spares and service strategy accordingly and contact Schneider Electric customer care for support, repairs or recommended replacements.
• Observe ambient operating limits (0…40 °C) and IP40 environmental requirements. Follow Schneider Electric wiring, grounding and EMC guidance.
