Precision and Brake Notes
The M2 encoder provides multiturn absolute feedback through EnDat 2.1. The RNNN configuration provides increased concentricity for applications sensitive to shaft runout. These features make the motor relevant for accurate indexing, precision coupling and controlled rotary transmission.
Brake option 2 supports stationary load retention. The brake is not a personnel-safety device and must not be used as a regular service brake. The complete motor weight can exceed the basic reference weight.
Replacement Checklist
- Confirm R911316296.
- Verify M2 EnDat 2.1 feedback.
- Check brake option 2 wiring and holding requirement.
- Confirm the plain-shaft coupling.
- Retain the RNNN increased-concentricity design.
