Frequently Asked Questions
What overload margin supports demanding cycles on MKD112B-048-KG1-RN?
It reaches 150 Nm maximum torque. That ceiling absorbs short, high-inertia events during acceleration or disturbance rejection, preserving loop stability and commanded path under aggressive motion profiles.
Which supply pairing optimizes modulation for MKD112B-048-KG1-RN drives?
It runs at 650 V rated voltage. Matching the inverter and DC link to this level maintains switching efficiency and current headroom for crisp torque production during rapid changes.
How is continuous electrical loading defined on MKD112B-048-KG1-RN?
It draws 20.3 A rated current. Cable gauge, protective devices, and drive thermal design are selected to support this value, ensuring reliable operation through extended duty cycles.
What assures safe holding on power-off for MKD112B-048-KG1-RN?
It includes a 22 Nm holding brake. The brake locks the shaft when de-energized, preventing gravity-induced drift and safeguarding tooling and parts during maintenance or outages.
Which mounting datum maintains concentricity on MKD112B-048-KG1-RN?
It uses a 130 mm centering diameter. The pilot provides coaxial alignment, reducing vibration and extending coupling life in long-run production.
