Frequently Asked Questions
What secures the axis on MKD112B-048-KG1-AN during shutdowns or e-stops?
It includes a 22 Nm holding brake. The spring-applied mechanism locks the shaft when de-energized, preventing unintended motion on vertical or inclined axes and preserving tooling or part alignment during service intervals.
How much current capacity frames the inverter choice for MKD112B-048-KG1-AN?
It draws 29.5 A rated current. That figure sets continuous drive sizing and cable gauge, ensuring thermal limits and voltage drop remain in spec while preserving dynamic response during frequent accelerate-decelerate profiles.
How does MKD112B-048-KG1-AN perform in challenging environments?
It meets IP65 protection class. Dust and water jets remain outside, protecting encoder electronics, terminals, and bearings so accuracy and dielectric integrity persist through washdown and abrasive airborne exposure.
Which interface keeps MKD112B-048-KG1-AN structurally stable?
It uses a 192 mm flange size. The wide, machined face maintains squareness and distributes loads, reducing micro-movement that can degrade coupling alignment during reversing duty.
How does mass influence dynamics on MKD112B-048-KG1-AN?
It weighs 67 kg. The higher mass damps vibration and lowers resonance amplitude, improving surface finish, path accuracy, and tool life in large frames or rigid automation cells.
