Frequently Asked Questions
How does the electrically released 32 Nm holding brake help on vertical Z-axes? (MSK100A-0300-NN-S1-BG1-NNNN)
It retains load when power is off to mitigate unintended motion during e-stop or drive disable. Its brake sizing offsets reflected inertia/weight to keep ballscrews or belt lifts stationary during maintenance.
Why choose a plain shaft variant for couplings versus keyed options on MSK100A-0300-NN-S1-BG1-NNNN?
Its plain shafts with shrink-disc or clamping hubs minimizes runout and torsional backlash for improving frequency response. It also avoid keyway stress risers that benefits dynamic reversing on gantries and spindles.
What electrical interface and cabling orientation should be planned? (MSK100A-0300-NN-S1-BG1-NNNN)
The B-side power connector provides flexible cabling to the IndraDrive. Its proper routing and shield termination are essential to maintain EMC compliance and preserve encoder signal integrity.
What encoder resolution (128 signal periods) means in practical positioning accuracy for the MSK100A-0300-NN-S1-BG1-NNNN?
Its each period interpolates via the drive for yielding fine electrical angle resolution and smooth torque production. Its effective line counts after interpolation define achievable cyclic error and permit tight contouring at low speeds.
Why specify natural-convection cooling on MSK100A-0300-NN-S1-BG1-NNNN for continuous duty?
The conduction and surface convection define the thermal path, so continuous torque at 100 K is predictable (≈17 Nm) without auxiliary fans or liquid circuits. It eases enclosure design and maintenance to provide ambient and mounting meet Rexroth thermal guidelines.
