Frequently Asked Questions
How does the “increased concentricity” design improve motion quality on MSK100A-0450-NN-M2-BG0-RNNN?
The shaft/hub runout lowers cogging-related torque ripple and mechanical vibration for enhancing interpolation at micro-increments. It yields cleaner surface finish in CNC axes and steadier camera/gantry trajectories in inspection cells.
Why is natural-convection cooling advantageous on MSK100A-0450-NN-M2-BG0-RNNN, and when would retrofitting fans or liquid cooling help?
The convection avoids fans for reducing particulates, noise and maintenance while maintaining thermal balance at moderate continuous load. For elevated continuous power, Rexroth provides axial/radial blowers and liquid-cooling options to extend duty capability.
How does the optical multiturn EnDat 2.1 encoder (2048 signal periods) in MSK100A-0450-NN-M2-BG0-RNNN aid servo precision?
The EnDat’s synchronous serial link transmits absolute position and parameter data deterministically for supporting stiff velocity/position loops. Its optical multiturn sensing and 2048 periods enables fine interpolation and reliable homing-free startup.
What do the standstill ratings mean for MSK100A-0450-NN-M2-BG0-RNNN (17.0 Nm at 13.6 A, 100 K)?
They specify continuous torque/current at a defined motor temperature risefor guiding thermal sizing in hold/low-speed regimes. It is important to use these with ambient and enclosure conditions to verify duty cycle margin.
What integration benefits come from the plain shaft and B-side power connector on MSK100A-0450-NN-M2-BG0-RNNN?
Its plain shaft simplifies coupling selection and alignment in retrofit shafts or precision hubs. Its standardized Rexroth connectors with IP-rated hardware and defined pinouts streamline cabling, temperature-sensor and brake provisions across MSK sizes.
