The Hiperface combines absolute position within one turn with analog sin/cos for high-resolution interpolation in the drive for improving commutation and low-speed smoothness. It also carries electronic nameplate data over RS-485 for rapid commissioning.

It continuously removes copper and iron losses so windings stay near the specified thermal point for sustaining the 14.0 Nm stall rating. It lower winding temperature drift maintains current-loop linearity and reduces thermal derating over long production runs.

The higher inductance filters PWM ripple for lowering copper heating and torque ripple at the expense of current-loop bandwidth. Its proper current-controller tuning (Kp/Ki) and bus voltage selection balance dynamic stiffness with smooth torque production.

It’s intended for backlash-controlled clamp or shrink-disk couplings that maintain concentricity and accommodate minor misalignment. Its torsional stiffness selection to match load inertia preserves servo bandwidth without exciting mechanical resonances.

The singleturn is sufficient if axes home at startup and absolute travel per cycle remains within one revolution. Its multiturn is preferred for multi-rev positioning, power-loss recovery without homing and coordinated multi-axis synchronization.
