How precise is the Hiperface singleturn optical encoder with “128 signal periods”?

Hiperface provides 128 sin/cos periods per rev with 5-bit absolute data per period (4096 distinct absolute positions/rev), and the drive can interpolate the analog sin/cos for finer resolution. That delivers high dynamic stiffness without the cogging of low-line count encoders.

What are the implications of “singleturn” feedback in multi-revolution moves?

Because it’s singleturn, absolute position is valid only within one turn, so on power-up you must home or use a reference to recover multi-turn position. For axes that may drift under load, add a home switch or external absolute reference strategy.

How should the liquid-cooling circuit be designed for reliability?

Use clean water coolant, inside-diameter ≥9 mm lines, and keep supply pressure at the motor ≤3 bar; design for required flow, temperature rise, and pressure drop across the loop. Avoid hard/floating network water to prevent scaling and corrosion

For a B2B retrofit, which controllers and currents should I check against?

Size the drive for the motor’s peak current capability (≈137.7 A for this winding) and verify speed-torque limits against the IndraDrive bus and mains configuration used in your plant. Confirm current-loop bandwidth and thermal model settings to fully utilize liquid-cooled ratings.

Does the keyed shaft affect balancing and coupling choice?

These motors are balanced “with key,” so select couplings/hubs accordingly and note the key is not included. Improper balancing can introduce runout and bearing loads at high speed.
