The R911328823 (MSK071C-0450-NN-M1-UP2-NNNN) is a Rexroth Indramat IndraDyn S synchronous servomotor with a motor size of 071 and length C. It features a brushless design and is rated to IP65 protection class, providing resistance to dust and water ingress. The motor operates with natural convection cooling (FN), and maintains optimal performance within an ambient temperature not exceeding 50°C. It includes a 30 Nm electrically-released holding brake and a shaft with keyway. The integrated multiturn absolute optical encoder uses a Hiperface interface and provides 128 signal periods, enabling precise feedback. Electrical connections are made with power and feedback cables via a 240-degree rotatable connector. The winding code is 0450, with continuous standstill current of 10.4 A, continuous standstill torque of 14.0 Nm, maximum current of 40.1 A, maximum torque of 44.0 Nm, and winding inductivity of 6,700 mH.

Frequently Asked Questions

What is the benefit of the 240° rotatable encoder connector during installation of the MSK071C-0450-NN-M1-UP2-NNNN?

The swiveling plug simplifies dress-pack routing and strain-relief in tight cabinets or moving carriages for reducing bending stress on feedback cables. Its better cable orientation also improves EMC layout discipline and serviceability in multi-axis machines.

How does the electrically released 30 Nm holding brake help in vertical-axis safety for MSK071C-0450-NN-M1-UP2-NNNN?

The spring-applied brake clamps to hold load when power is removed for preventing back-driving on Z-axes or gantries. It electrical release enables smooth torque takeover by the servo loop on power-up for limiting step change in position under suspended loads.

Does the MSK071C-0450-NN-M1-UP2-NNNN support industrial environmental protection levels?

The MSK071C variants are available with IP65 protection to offer dust-tight construction and water-jet resistance around connectors and seals. It suits wash-down-adjacent packaging zones and many machine-tool enclosures with appropriate cabling glands.

How do the 128 signal periods of the optical encoder translate to motion control resolution on MSK071C-0450-NN-M1-UP2-NNNN?

The analog sin/cos periods are multiplied by serial counts (32× rule) and drive interpolation for yielding fine electrical angle granularity. It enables tight velocity ripple control and low cogging effects during contouring.

What do the current ratings (10.4 A continuous at standstill, 40.1 A maximum) imply for drive selection on MSK071C-0450-NN-M1-UP2-NNNN?

The IndraDrive (or equivalent) requires continuous current headroom for thermal steady-state and peak current capacity for transient torque. Its cable gauge and DC bus capability must support ~44 Nm peaks without saturating or tripping current limits.

Common Misspellings

Internal Product Review

The servo motor MSK071C-0450-NN-M1-UP2-NNNN from Bosch integrates a multiturn absolute Hiperface optical encoder of 128 periods of positioning and the encoder connects via 240° rotatable plug. It has an electrically released 30 Nm brake system and it possess a keyed design of shaft. This unit supports up to 44 Nm peak torque and offers IP65 protection to cope in industrial environments.
