The keyway ensures torque transmission stability under load but can introduce stress concentrations and alignment errors if not machined precisely. For high-precision axis motion, backlash in the key-seat and key-fit tolerances must be considered and minimized.

The MDD series typically assumes ambient operation ~0–45 °C and installation below ~1000 m altitude before derating. Forced ventilation or additional cooling may be required under heavier loads or in enclosed cabinets.

Bosch recommends keeping the feedback cable length under about 75 meters to maintain integrity of the digital signals and prevent latency or signal distortion.

For systems needing safe lock-in position during power loss (e.g. vertical, safety axes), choose versions with holding brakes; for high-speed axes where inertia and dynamic response dominate, brakeless models often yield better performance. Use external brakes only if integration or safety requirements demand them.

That torque rating means the motor can hold or generate sustained force when stationary — useful for resisting external loads or gravity without slipping. In dynamic applications, this informs sizing margins to avoid overheating or saturation during high torque demands.
