The R911327947 (MSK101D-0450-NN-S2-AG2-RNNN) is a Rexroth IndraDyn S synchronous servomotor engineered for industrial applications requiring IP65-class protection. It features a plain steel output shaft with sealing rings and supports cooling via natural convection, with optional air blower attachment. The embedded single-turn optical encoder (EnDat2.1, 2048 signal periods) provides feedback for control accuracy. The motor measures size 101, length D, with winding code 0450. Key specifications include 57.0 Nm continuous torque at standstill (100 K), 50.6 A continuous current at standstill (100 K), 160.0 Nm maximum torque, 187.7 A maximum current, and 1,700 mH winding inductivity. It includes an electrically-released holding brake (70 Nm torque) and is designed for increased concentricity.

How does the EnDat2.1 interface improve communication between the servo motor and the drive controller?

The EnDat2.1 interface allows digital transmission of position and diagnostic data ensuring precise and interference free communication. The result is higher control accuracy and simplified cabling in automation setups.

Why is increased concentricity important for servo motor performance?

The increased concentricity minimizes mechanical runout which enhances motion smoothness and accuracy. The benefit is more reliable positioning and reduced vibration during high speed operation.

What is the practical impact of a 2048 signal periods encoder resolution?

The high resolution encoder provides fine position feedback for precise control of rotational movements. The result is smoother motion and higher repeatability in automated machinery.

How does an electrically released holding brake enhance operational safety?

The holding brake engages automatically when power is removed securing the motor shaft in position. The feature prevents mechanical drift or load movement during emergency stops or power loss.

How does requiring Cooling FN affect installation planning?

The requirement indicates the motor must be mounted where sufficient airflow or cooling clearance is available. The proper installation ensures stable thermal behavior and extended service life.
