Frequently Asked Questions

How does increased concentricity in the MSK100B-0200-NN-M2-BG2-RNNN improve servo accuracy and reliability?

Its concentricity minimizes radial runout and torque ripple for raising effective servo stiffness and contouring fidelity. Its reduced vibration lessens bearing loads for extending service intervals and improving surface finish on machine-tool or indexing applications.

Why choose natural-convection cooling on MSK100B-0200-NN-M2-BG2-RNNN versus forced ventilation?

Its passive cooling removes fans and filters for simplifying maintenance and improving cabinet sealing for dusty or washdown-adjacent environments. Its thermal design must still respect ambient and duty.

How does the 7,600 mH winding inductivity affect current-loop tuning and torque smoothness?

The higher inductance increases the electrical time constant for filtering current ripple and smoothing torque at low speed. Its drive tuning may use slightly reduced current-loop bandwidth and adjusted PI gains to maintain phase margin during rapid transients.

What is the role of the 70 Nm electrically released holding brake on MSK100B-0200-NN-M2-BG2-RNNN?

It mechanically secures vertical or overhauling loads at standstill or power-off for preventing axis drift. It is a holding device, not a dynamic emergency-stop brake.

What mechanical implications do the plain shaft and B-side power connector have on MSK100B-0200-NN-M2-BG2-RNNN installation?

The plain shaft favors backlash-free couplings or press-fit gearheads, while precise alignment minimizes radial/axial loads. Its B-side connector eases cable routing in tight enclosures to maintain bend radii and EMC practices for encoder and power leads.
