Product Overview
The Bosch Rexroth MSK040B-0600-NN-S1-UP0-NNNN is an IndraDyn S synchronous servo motor designed for controlled rotary motion in industrial automation equipment. It converts electrical output from a compatible servo drive into mechanical torque for machine axes that require managed speed, acceleration, and positioning. The MSK series is used in applications such as machine tools, packaging machinery, and automated handling systems. Selection should be based on the motor’s complete type code and the electrical and mechanical requirements of the target axis, rather than the MSK family name alone.
This configuration identifies a size 040, length B motor with winding code 0600, natural-convection cooling, and an optical singleturn Hiperface encoder. The feedback device provides 128 signal periods, and its electrical connector can rotate through 240 degrees to accommodate installation constraints. The shaft uses a keyway for mechanical torque transmission, while the UP0 configuration is listed without a holding brake. These details matter when replacing a failed motor: encoder type, shaft geometry, connector clearance, and brake requirements can affect commissioning and mechanical integration.
For procurement and maintenance teams, the Bosch Rexroth MSK040B-0600-NN-S1-UP0-NNNN should be verified against the installed drive’s approved motor data and the machine’s original bill of materials. Supplier listings report approximately 1.7–1.9 Nm standstill torque, 5.1 Nm maximum torque, and a maximum current of 8 A; confirm the exact rating basis against the applicable Rexroth documentation before using those values for sizing or protection settings. The motor has no integral holding brake, so vertical axes or suspended loads require an independently engineered holding and safety arrangement. Confirm actual condition with supplier, and inspect the nameplate, connector, shaft, and encoder feedback before installation.

Frequently Asked Questions
Q1: Can the MSK040B-0600-NN-S1-UP0-NNNN be hot-swapped?
Do not treat it as a hot-swappable component. Isolate power and follow the machine’s lockout, stored-energy, and drive-manufacturer procedures before disconnecting or installing the motor.
Q2: Is firmware required for this motor?
The motor itself is not typically described as a standalone firmware device. The compatible drive controller must be configured with the correct motor data and supported control parameters. Confirm the procedure for the installed IndraDrive model.
Q3: How do I confirm compatibility with an existing drive?
Check the full motor type code and order number, drive model, motor power and current limits, encoder interface, feedback cable, and application torque-speed requirements. A shared MSK family designation alone does not establish compatibility.
Q4: Does this motor have a holding brake?
No. The UP0 configuration is listed without a holding brake. For vertical or suspended loads, assess the need for an independent load-holding mechanism and follow the machine’s safety design.
Q5: Can motor parameters or position data be lost?
The S1 encoder is singleturn. Rexroth documentation distinguishes singleturn feedback from multiturn versions, so the system’s homing and position recovery behavior must be reviewed after power loss or motor replacement. Follow the drive and machine commissioning procedures.
Q6: How can I verify authenticity and condition?
Request clear nameplate photos, the complete type code, order number, connector and shaft photos, and any inspection or repair records. Confirm actual condition with supplier; do not infer factory-new status from the model number alone.
Q7: What maintenance should be planned?
Inspect the shaft, bearings, mounting interface, connectors, cables, and encoder feedback as part of the machine’s maintenance program. Investigate abnormal vibration, noise, overheating, or position errors before returning the axis to service. Use the applicable Rexroth operating instructions for handling and installation requirements.
