The optical single-turn Hiperface (S1) scale provides finely interpolated commutation and position data for enabling tight velocity and position loops. Its 128 signal periods support granular interpolation for reducing quantization error in machine-tool and robot axes.

Its natural convection eliminates fan wear, reduces acoustic emissions and simplifies maintenance. For elevated continuous torque or confined enclosures, surface-ventilated or liquid-cooled MSK variants lower thermal resistance to extend duty at speed without exceeding winding temperature limits.

The A-side flange socket streamlines cable routing and strain relief on machines with left-hand cable channels for helping minimize bend radius violations. It also separates power from feedback paths predictably for aiding EMC practices and service accessibility.

The precision cylindrical (plain) shaft works excellently with shrink-fit or clamp couplings for providing concentricity and low backlash. Its DIN keyway option can be specified, while torque capacity depends on hub geometry and locking method.

The rated standstill current defines thermal headroom for holding torque and stiffness at zero speed. Its higher phase inductance attenuates current ripple for easing current-loop tuning and enabling smooth torque production under rapidly changing loads.
