Frequently Asked Questions
Why is the 240° rotatable connector useful on the MSK071C-0300-NN-M2-UG2-RNNN?
The adjustable flange socket lets installers aim the connector to relieve bend radius to avoid cable clashes and simplify enclosure-to-machine routing. It allows both the 240° adjustment and the allowable reorientation torque/limits.
Is the 30 Nm electrically-released brake on MSK071C-0300-NN-M2-UG2-RNNN for stopping or holding?
It’s a holding/parking brake intended to secure the axis at standstill, while dynamic deceleration remains a drive function. It explicitly allows holding at standstill with electrically-released operation.
What continuous current/torque values define drive sizing for MSK071C-0300-NN-M2-UG2-RNNN at 100 K?
Its typical listings show 8.5 A continuous current and 14 Nm continuous torque for guiding current-loop and thermal sizing. Its peak vectors of 32.9 A and 44 Nm shape short-term dynamics and acceleration envelopes.
How does the “increased concentricity” design of MSK071C-0300-NN-M2-UG2-RNNN benefit mechanics and couplings?
Its tighter shaft concentricity reduces runout-induced radial load for improving bearing life and minimizing coupling misalignment excitation. It helps maintain low vibration and repeatable motion profiles in precision assemblies.
When should a plain shaft (UG2) be preferred on MSK071C-0300-NN-M2-UG2-RNNN, and what coupling styles fit?
The plain shafts pairs well with friction-fit, zero-backlash elastomer or metal bellows couplings for precise torque transmission. It simplifies assembly while maintaining torsional stiffness without keyway micro-play.
