The M2 encoder provides multiturn absolute position feedback through the EnDat 2.1 interface. The RNNN suffix identifies increased concentricity and should be retained where shaft runout affects the connected mechanism.
The plain shaft requires a properly rated clamping coupling. Brake code 0 confirms that no integrated holding brake is installed. The machine must provide another load-holding method when required.
Typical applications include high-speed indexing, packaging machinery, printing systems, robotics, assembly equipment and compact machine-tool axes. Drive sizing must consider the higher-speed 0300 winding and its current requirements.
