Frequently Asked Questions
How do the 8.5 A standstill current and 14.0 Nm continuous standstill torque on MSK071C-0300-NN-M2-UP1-RNNN affect axis sizing?
They define continuous thermal load at zero speed for holding or feed. Its gear ratio, duty cycle and cooling must preserve margin before approaching the 32.9 A, 44 Nm peak limits.
Why is a multiturn absolute optical encoder with EnDat 2.1 used on MSK071C-0300-NN-M2-UP1-RNNN?
It preserves absolute position through power cycles and reports diagnostics over a digital link. Its EnDat 2.1 simplifies cabling to improve noise immunity and shortens commissioning versus incremental encoders with homing routines.
What is the practical effect of a 10,900 mH winding inductivity in the MSK071C package?
The inductance filters current ripple and linearizes torque for improving low-speed smoothness. It also limits current-loop bandwidth, so drive tuning must balance responsiveness against stability and PWM switching losses.
How does the electrically released, 23 Nm holding brake in MSK071C-0300-NN-M2-UP1-RNNN improve safety and startup?
The brake holds the axis unpowered and releases only when energized to prevent drift. Its capacity suits vertical axes and fixtures for mitigating sag during e-stop, jog and initial encoder alignment.
What benefits does the “increased concentricity” mechanical design bring to servo performance?
Its reduced runout lowers vibration and bearing load for enabling tighter position gains. Its better rotor balance reduces periodic disturbance that yields cleaner contour accuracy and improved surface finish on interpolated paths.

Internal Product Review
The Bosch's servo motor MSK071C-0300-NN-M2-UP1-RNNN possess a multiturn absolute optical encoder (EnDat 2.1) that connects through a rotatable 240° connector. It uses natural-convection cooling and comes with an increased concentricity temper vibration. This motor has a keyed shaft and 23 Nm electrically released brake for secure load management in packaging, printing, robotics and machine tools.
