With 2048 signal periods per revolution and multiturn count, the controller can achieve high positional fidelity over many turns and reduce quantization error in closed-loop motion.

The MSK series datasheet defines permissible radial and axial bearing loads for each size to avoid premature bearing failure—exceeding these limits shortens life and impacts positional accuracy.

The thermal time constant is 100 minutes, meaning that heat buildup and temperature rise during short bursts is slow—so short overloads are tolerated, but sustained overloads will overheat the motor.

Better concentricity reduces run-out and mechanical vibration in the rotor–stator gap, improving positional accuracy and lowering wear on bearings and adjacent gears in high-precision applications.

Its high continuous and peak torque, standardized interface (EnDat 2.1), and modular form factor make it suitable for synchronized multi-axis motion, but you must ensure that your drive controller supports its electrical and feedback interface and that the cooling and mounting demands are met.
