Frequently Asked Questions
What advantages does liquid cooling provide on the MSK071C-0300-FN-S1-UG0-NNNN in duty cycles with high thermal load?
The liquid circuits remove copper/iron losses directly from the stator jacket for stabilizing winding temperature and allowing higher continuous torque density. It is valuable for cyclic start-stop processes or extended continuous operation where air cooling would impose derating.
How does the optical singleturn Hiperface encoder in MSK071C-0300-FN-S1-UG0-NNNN aid precision motion?
The singleturn optical system provides precise absolute position within one revolution and low interpolation error for enabling tight velocity and position loops. Its Hiperface ensures robust parameter readout and commissioning with Rexroth drives.
Why specify a plain shaft on MSK071C-0300-FN-S1-UG0-NNNN, and what couplings suit it?
The plain (cylindrical) shaft supports backlash-free, frictional couplings (e.g., clamping or bellows) for low runout and torsional stiffness. It simplifies alignment in precision axes versus keyed interfaces, especially in servo applications.
What is the role of the 240° rotatable power/encoder connector on MSK071C-0300-FN-S1-UG0-NNNN?
The swiveling connector eases cable routing in confined frames that minimizes bend-radius stress, and improves serviceability. Installers can orient terminations to avoid drag chains or interference with guarding.
How should I interpret 14.0 Nm continuous torque at standstill (100 K) for MSK071C-0300-FN-S1-UG0-NNNN?
It’s the continuous stall torque with a 100 K permissible winding temperature rise under specified cooling for guiding safe thermal sizing.
