Frequently Asked Questions

Why is the 70 Nm electrically released holding brake important on MSK101C-0300-NN-M2-AG2-RNNN?

The 24 VDC, spring-applied/energize-to-release brake secures vertical or load-holding axes during e-stop or power loss. It limits back-driving and simplifies compliance with safety stop functions on Z-axes.

What encoder configuration does MSK101C-0300-NN-M2-AG2-RNNN use and why does it matter?

It uses an optical multiturn absolute encoder that is EnDat 2.1 with 2048 signal periods for enabling precise multi-rev position capture and secure parameterization. It improves repeatability and simplifies homing for coordinated axes.

How does natural-convection cooling influence integration of MSK101C-0300-NN-M2-AG2-RNNN?

Its fanless thermal dissipation reduces components and acoustic emissions for easing maintenance and enclosure design. It suits cabinets or machine frames where airflow is available, while leaving headroom for external “FN” cooling if the duty cycle later increases.

What does “increased concentricity” imply for MSK101C-0300-NN-M2-AG2-RNNN?

The tighter shaft runout and rotor alignment reduces radial error motion to improve encoder fidelity and gearbox life. It’s advantageous for high-precision indexing or web handling where synchronous velocity tracking is critical.

How does winding inductivity (~6,000 mH) and rated speed code “0300” affect drive tuning for MSK101C-0300-NN-M2-AG2-RNNN?

The higher inductivity smooths current ripple for enabling stable current loops; drive parameters can use higher gains without oscillation. Its speed code sets base back-EMF constants to influence achievable speed/torque curves and bus voltage selection.
