Even small misalignment or angular offset can introduce radial loading that shortens bearing life, so flange and coupling alignment must stay within manufacturer-specified tolerances. Also, the 130 mm centering diameter demands matching precision in the mating surface to avoid eccentric loading.

The brake must be released (powered) before motion, adding a small delay in control logic, and residual drag or friction from the brake mechanism can minimally affect low-torque moves. In high repeat-motion cycles, frequent brake actuation may marginally heat the brake coil and slightly influence duty cycling.

Because the encoder is absolute and multiturn, it retains its position across power cycles, eliminating the need for homing moves and enabling immediate closed-loop control. The DSF (digital servo feedback) provides real-time rotor position to the controller, enhancing control bandwidth and reducing latency in motion loops.

At standstill the motor draws its maximum current, so cables, connectors and drive hardware must be rated to that peak current at ambient and temperature derating. Also ensure the drive’s current limit and thermal model support continuous holding without overtemperature.

The keyway introduces a stress concentration and slightly reduces torsional stiffness compared to a plain shaft, so select couplings that accommodate the key and avoid altering the stress profile. Also, ensure the key is properly sized and seated to prevent backlash in high-precision use.
