Even slight radial or angular misalignment beyond a few hundred micrometers can cause bearing stress and vibration; ensure the centering diameter (110 mm) is accurately referenced and coupling alignment is within spec to preserve motor life.

The encoder stores absolute rotor position across power cycles, reducing or eliminating the need for separate homing routines after restart. This stability shortens commissioning and downtime in closed-loop applications.

The motor’s rated ambient limit is ~45 °C, beyond which the controller may need to derate torque or current; at ~55 °C in derated mode, safe continuous operation is still possible per vendor datasheets.

The keyway ensures positive, backlash-free torque transfer, but you must size the key and coupling to avoid local stress concentrations; avoid shock loads or misaligned coupling that could shear the key or damage the shaft.

DSF yields very high-resolution, real-time position/velocity feedback, enabling tighter loop gains and better disturbance rejection; but the drive/controller must support the DSF protocol and handle its data rate and initialization requirements.
