Product Overview

The Rexroth R911312990 MSK101E-0200-NN-S2-AG0-RNNN is a large-frame MSK servo motor equipped with an S2 single-turn EnDat 2.1 encoder and increased-concentricity construction. It is intended for high-torque industrial axes where accurate feedback and controlled mechanical runout are important.

Product Information

Reference Base-Motor Data

Precision Configuration

The S2 encoder uses the EnDat 2.1 interface with 2,048 signal periods. It provides absolute angular position within one shaft revolution. Drive and feedback-cable compatibility must be confirmed.

The RNNN ending means increased concentricity. It does not indicate ATEX construction. This configuration can be valuable where the motor is directly coupled to a precision gearbox, roller, ballscrew or measuring mechanism.

The motor has a plain shaft and no integrated holding brake. Coupling and load-holding requirements must therefore be addressed separately.

Typical Applications

Typical uses include precision machine tools, printing machinery, converting systems, high-torque handling equipment, winding lines and automated production modules.

• Confirm material number R911312990.
• Verify the S2 EnDat 2.1 interface.
• Check the A-side connector position.
• Retain the RNNN accuracy configuration.
• Confirm that no integrated brake is required.
