The MSK071C-0450-NN-M1-UP2-NNNN servomotor from Bosch Rexroth Indramat is part of the MSK IndraDyn S Synchronous Motors series. It uses absolute optical encoding via a rotatable 240° Hiperface connector with 128 signal periods and natural convection cooling. The standard design includes an electrically released holding brake with 30 Nm torque and a shaft with keyway. It delivers a maximum torque of 44 Nm and requires Cooling FN.

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.
