Frequently Asked Questions

What applications benefit from the single-turn (vs. multi-turn) encoder in MSK101C-0300-NN-S3-FB0-NPNN?

Th single-turn absolute feedback is well-suited to short-stroke linear mechanics, rotary indexing tables and belt axes that reference within one revolution. Its multi-turn is preferred when absolute position must persist across many turns without homing.

How does the motor’s winding inductivity (catalogued ~6,000 mH**) influence the chosen drive and current loop?**

Its higher phase inductivity limits ripple and eases current-loop stability but constrains electrical bandwidth, while drive tuning must balance response with switching-frequency limits. It is important to select an IndraDrive amplifier with suitable voltage/current headroom and PWM rate.

How does the B5 flange (IEC) mounting of MSK101C-0300-NN-S3-FB0-NPNN affect mechanics?

The flange assembly enables rigid face-mounting to gearheads or machine plates, forimproving concentricity and reducing overhung load on the shaft. It contributes to bearing-life targets when radial/axial loads remain within the MSK tables.

Why a terminal-box connector instead of molded connectors on MSK101C-0300-NN-S3-FB0-NPNN?

The terminal-box layout simplifies field wiring to segregate power/feedback and serviceability in larger frames. It complies with Rexroth’s standardized MSK connection practices and supports temperature sensor and encoder cabling through defined glands.

What torque/current envelope characterizes MSK101C-0300-NN-S3-FB0-NPNN at standstill and peak?

The typical catalog figures for this type code are 36.5 Nm continuous at 100 K and 110 Nm peak that is reached with about 84.2 A maximum current. Its ambient and mounting conditions to validates thermal margins.
