Frequently Asked Questions
What advantages does the M3 multiturn Hiperface encoder bring on MSK071C-0200-NN-M3-UG1-NNNN, and why is it preferred for coordinated multi-axis machines?
The M3 variant provides absolute position across revolutions (multi-turn) with capacitive sensing and Hiperface communication for aiding deterministic homing-free startups and safe motion recovery.
How does the 240° rotatable motor/encoder connector help during commissioning of MSK071C-0200-NN-M3-UG1-NNNN?
The swiveling connector simplifies cable exit routing in tight cabinets and gantry frames for reducing bend-radius stress and installation time. It also helps maintain shielding integrity by orienting connectors away from noise sources and moving cable chains.
Why use an electrically released 23 Nm holding brake on MSK071C-0200-NN-M3-UG1-NNNN, and when does it engage?
It is spring-applied, power-off safe for engaging on e-stop or power loss to hold vertical/z-axes or indexers up to its rated static torque. Its electrical release during power operation prevents back-driving and improves restart accuracy after stops.
How does the specified winding inductivity (19,500 mH) of MSK071C-0200-NN-M3-UG1-NNNN influence drive tuning and current ripple?
The higher phase inductance attenuates PWM ripple and helps current-loop stability to allow smoother torque at low speed. It may require appropriate current-controller bandwidth and voltage headroom to maintain dynamic response during fast transients.
What are the design implications of natural-convection cooling on this motor’s continuous torque?
The passive cooling helps in the delivery of continuous torque at thermal steady state, while ambient airflow and mounting affect achievable duty. Where higher continuous output is needed, the MSK platform supports blower or liquid-cooling variants for other models in the family.

Internal Product Review
The Rexroth Indramat’s MSK071C-0200-NN-M3-UG1-NNNN servomotor uses an M3 multiturn capacitive Hiperface encoder through a 240° rotatable connector for feedback. It comes with a plain-shaft mechanics and relies on natural-convection cooling. It supplies 14 Nm continuous and 44 Nm peak torque, while draws 23.4 A of peak current. This motor has a 23 Nm electrically released brake that makes it well-suited for controlled robotics and automation work.
