What happens to positioning accuracy if the multiturn absolute encoder loses power?

Because the encoder is absolute, the motor will regain its exact position on power-up—no homing cycle is needed, which minimizes downtime in B2B automation cells.

How critical is thermal management for this motor when running near its continuous torque?

Operating close to 10.4 Nm continuously increases internal losses and heat; to avoid thermal derating, cooling strategy (natural convection or surface cooling) must ensure winding temperature stays within safe ranges.

What wiring considerations are implied by the side-A connector layout?

Side-A connection imposes routing constraints—ensure cable bend radius, strain relief, and shielding are accounted for on the motor’s “A side” to avoid interference or mechanical stress.

In a multi-axis machine, how does the centering diameter of 110 mm benefit mechanical integration?

The 110 mm centering ensures consistent alignment with standard flanges and mounting plates, easing interchangeability or modular design across axes.

What trade-offs exist in using the keyway shaft plus shaft seal design?

The keyway gives positive torque coupling to hubs or gears, but increases stress concentration; the shaft seal protects against contamination but may add friction or limit speed due to sealing drag.
