Description
Product introduction
In automated production equipment, the servo motor must match the drive’s feedback system, torque requirements, and mechanical interface. The Bosch Rexroth MSK040C-0600-NN-M1-UG1-NNNN is suited to applications built around compatible IndraDrive control hardware, where accurate position feedback and holding-brake functionality are required.
For replacement planning, the R911306061 material number is an important cross-check. Confirm the encoder type, brake wiring, shaft dimensions, connector orientation, and drive parameters before installing the Bosch Rexroth MSK040C-0600-NN-M1-UG1-NNNN. A motor with a similar MSK designation may have a different encoder or brake configuration.

MSK040C-0600-NN-M1-UG1-NNNN
Application scenarios and maintenance considerations
- CNC and machine tools: Servo-driven axes requiring position feedback and controlled acceleration.
- Automated assembly equipment: Coordinated motion for indexing, transfer, and precision positioning.
- Packaging machinery: Repeated motion cycles where encoder feedback and brake operation must match the machine sequence.
- Legacy IndraDrive systems: Replacement of an installed motor while preserving the original drive architecture and parameter configuration.
Field note: The holding brake is intended to hold a stationary load, not to serve as the normal dynamic stopping device. Confirm that the drive’s braking sequence and mechanical load requirements are appropriate before commissioning.

| MSK050C-0600-NN-M1-UG1-NNNN — R911298355 | Larger MSK050 frame configuration |
These are related catalog variants, not automatic substitutes. Verify mechanical fit, encoder compatibility, torque, speed, and drive sizing before selecting an alternative.
Engineer’s replacement checklist
- Match the identification: Confirm both
MSK040C-0600-NN-M1-UG1-NNNNand material numberR911306061. - Verify feedback and brake circuits: Check Hiperface encoder compatibility, brake voltage, wiring, and drive configuration.
- Inspect mechanical fit: Compare the shaft, seal, flange, connector orientation, and mounting dimensions. After installation, perform the approved motor identification and commissioning procedure.
Frequently asked questions
1. What is the Bosch Rexroth MSK040C-0600-NN-M1-?
It is an IndraDyn S permanent-magnet synchronous servo motor with a multiturn absolute encoder and an electrically released holding brake.
2. What is its material number?
The matching material number is R911306061.
3. Does this motor include a holding brake?
Yes. The UG1 configuration is listed with a holding brake. The corresponding UG0 variant is listed without one.
4. Which encoder does it use?
The M1 configuration uses a multiturn absolute Hiperface encoder. Confirm the installed drive supports this feedback type before replacement.
5. Is it interchangeable with another MSK040 motor?
Not necessarily. Encoder type, brake option, shaft configuration, and electrical characteristics must match the application.
6. What information should be checked before purchase?
Provide the complete model code, material number, nameplate photograph, connector details, and existing drive model. Also confirm whether the required unit is new, unused surplus, or tested used stock.
