MSK071C-0300-FN-M2-UG2-RNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK071C-0300-FN-M2-UG2-RNNN is a high-performance servo motor belonging to the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S Synchronous Servomotor, this unit features liquid cooling and delivers a continuous torque at standstill of 14.0 Nm at 100 K. With a maximum torque of 44.0 Nm and a rated speed code of 0300, it is designed for demanding precision motion control tasks in automated production systems. The unit’s primary function is to provide reliable, high-precision rotary motion for industrial robotics, packaging machines, and CNC equipment.
Incorporating advanced optical encoder technology, the motor supports a multiturn absolute encoder with an EnDat2.1 interface, offering an encoder resolution of 2048 signal periods. The rotatable encoder connector (240°) simplifies installation in confined spaces and maximizes flexibility. Constructed with a plain shaft and an increased concentricity design, the MSK071C-0300-FN-M2-UG2-RNNN accommodates precise alignment and minimal mechanical runout. Electrical characteristics include a winding inductivity of 10,900 mH, a continuous current at standstill of 8.5 A (100 K), and a maximum current of 32.9 A.
This servomotor is equipped with a robust electrically-released holding brake providing 30 Nm of torque, ensuring safe and stable load holding when de-energized. The requirement for the FN liquid cooling variant enhances thermal management under continuous operation, improving efficiency and preventing overheating. Its plain shaft design and increased concentricity contribute to enhanced durability and reduced maintenance needs. Compliant with Bosch Rexroth Indramat’s rigorous quality standards, this motor offers precise, repeatable performance and long service life. Ideal for industrial applications, it delivers superior dynamic response and energy efficiency, reducing cycle times and operational costs.

Frequently Asked Questions
How does the EnDat 2.1 multiturn (2048 periods) encoder in MSK071C-0300-FN-M2-UG2-RNNN improve positioning accuracy and avoid homing?
The optical EnDat 2.1 multiturn encoder supplies absolute position over 4,096 mechanical revolutions with 2,048 signal periods for fine interpolation, so axes retain position across power cycles. It eliminates homing routines, shortens startup and improves closed-loop resolution on robotics, packaging and CNC axes.
How does the 240° rotatable power/encoder connector on MSK071C-0300-FN-M2-UG2-RNNN aid machine layout and serviceability?
The “U” electrical connection option provides a 240° rotatable plug to let installers aim cable exits away from obstructions and maintain bend-radius in dense panels. Its flexibility eases routing to reduce strain on feedback leads during maintenance and supports rapid module swaps in multi-axis machines.
What is the function of the electrically-released 30 Nm holding brake in MSK071C-0300-FN-M2-UG2-RNNN on vertical or safety-critical axes?
The integrated holding brake is spring-applied and electrically released for delivering about 30 Nm static torque to secure the load when power is removed or during E-stop events. It prevents back-driving on vertical axes that stabilizes positioning during servo disable and simplifies compliance with safe-torque-off strategies.
What does the plain shaft with increased concentricity on MSK071C-0300-FN-M2-UG2-RNNN imply for coupling selection and runout?
Its plain shaft with increased concentricity minimizes total indicated runout at the coupling to aid smooth rotation and lower vibration in high-repeatability axes.
How does the multiturn absolute range (up to 4,096 mechanical revolutions) interact with machine kinematics on MSK071C-0300-FN-M2-UG2-RNNN?
The absolute tracking across 4,096 revolutions accommodates reducers and long-travel axes without index switches for preserving position through power interruptions. It when combined with safe-torque-off at the drive, the axis can re-enable to a known position quickly for improving OEE on tightly scheduled packaging or robotic workcells.
