Product Overview

The Rexroth R911312986 MSK071E-0300-FN-S2-UG2-RNNN is a fan-cooled synchronous servo motor configured for demanding continuous-duty motion applications. It combines S2 single-turn EnDat 2.1 feedback, a rotatable connector, plain sealed shaft, holding-brake option 2 and increased-concentricity construction.

The complete FN fan-cooled and brake-equipped configuration can have different continuous-duty and weight values from the naturally cooled basic motor. Confirm the configuration-specific data before final drive sizing or freight calculation.

Cooling, Brake and Encoder Notes

Fan cooling supports higher continuous thermal loading when the specified airflow is maintained. The fan power supply, airflow direction, mounting clearance and fan condition must be checked.

The S2 encoder requires an EnDat 2.1-compatible drive interface. Brake option 2 is intended for holding a stationary axis and must not be used as a normal dynamic stopping brake.

The RNNN suffix identifies increased concentricity. This can be valuable for precision coupling and smooth rotary transmission.

Replacement Checklist

  • Confirm the FN fan-cooled construction.
  • Verify S2 EnDat 2.1 feedback.
  • Check the fan supply and installation clearance.
  • Verify brake option 2 wiring.
  • Retain the RNNN design where required.
