Frequently Asked Questions about MS2N06-B1BNN-BSUL1-NNNNN-NN:

Q: How does the 128-period encoder improve motor performance?

A: The encoder provides high-resolution feedback for precise shaft positioning. The result is improved accuracy in motion control applications.

Q: Why is the rotor inertia of 0.00059 kgm² important?

A: The low rotor inertia allows quicker response times and smooth acceleration. The MS2N06-B1BNN-BSUL1-NNNNN-NN benefits from balanced motion and lower energy use.

Q: What role does the 52.4 mH winding inductance play?

A: The high inductance improves current regulation and smoothens torque delivery. The design helps reduce vibration and electromagnetic noise.

Q: How does the holding brake’s 24 V system affect safety?

A: The 24 V electrically released brake ensures stable stopping under power-off conditions. The system adds mechanical holding in vertical or load-sensitive axes.

Q: What are the implications of the 12.2-minute motor time constant?

A: The longer thermal time constant provides thermal stability over extended runs. The motor maintains consistent output without frequent cooling cycles.
