Product Overview
The Rexroth R911317820 MSK100B-0200-NN-M2-AP0-RNNN is a synchronous servo motor for industrial motion-control systems requiring high torque, multiturn absolute feedback and a keyed mechanical connection. The configuration uses natural-convection cooling and an increased-concentricity RNNN design.

Functional Characteristics
The M2 encoder provides multiturn absolute position feedback through EnDat 2.1. It is important to verify the drive interface because M2 is not directly interchangeable with S1, S2 or M1 feedback systems.
The P shaft code identifies a keyway according to DIN 6885-1 with a shaft sealing ring. The key, coupling, alignment and permissible radial loading must be checked during installation. The motor does not include a holding brake.
The RNNN design provides increased concentricity for applications where shaft runout and smooth rotary transmission are important. This suffix should be retained when replacing a motor used with precision gearboxes, couplings, rollers or measuring mechanisms.
Applications and Compatibility
Suitable applications may include printing machinery, metal-forming equipment, packaging lines, machine tools, handling axes and winding equipment. Confirm motor cable, encoder cable, drive firmware, connector clearance, shaft dimensions and controller parameters before installation.
