Bosch Rexroth MS2N06-D1BNN-CSSG0-NNNNN-NN Servo Motor – Obsolete MS2N Series Spare Part

RFQ support for obsolete parts: Send the model number, required quantity and destination so DriveKNMS can confirm sourcing options before quotation.

Technical Specifications

Note: Electrical parameters (rated torque, rated speed, rated current, winding voltage) vary by exact winding code. Confirm your drive's motor data set before installation. DriveKNMS does not publish unverified electrical data.

Solving the Discontinued Hardware Crisis

The MS2N series was Bosch Rexroth's mid-range synchronous servo platform, widely deployed across packaging machinery, injection molding, printing presses, and precision assembly lines throughout the 2000s and 2010s. These motors were engineered to operate within the IndraDrive ecosystem — the drive firmware, motor data sets (MDS), and feedback protocols are tightly coupled. Substituting a motor from a different manufacturer or even a different Rexroth series requires re-parameterization of the drive, re-commissioning of the axis, and in many cases, a new motor data set file that the OEM machine builder must validate.

Maintaining a verified spare MS2N06-D1BNN-CSSG0-NNNNN-NN on the shelf eliminates that risk entirely. A failed motor is swapped in under two hours by in-house maintenance staff. The drive recognizes the motor immediately. Production resumes. The capital expenditure decision — whether to upgrade or extend — remains in the hands of plant management rather than being forced by an emergency breakdown.

Extending Automation Asset Life by 5–10 Years: A Practical Framework

Facilities managing aging Rexroth IndraDrive or Indramat-era systems face a structured decision: invest in a controlled upgrade on a planned timeline, or extend the existing system's operational life while that upgrade is budgeted and scheduled. The second path is viable — but only with disciplined spare parts management.

Condition & Reliability Assurance

Discontinued servo motors sourced from the secondary market carry inherent risk if not properly evaluated. DriveKNMS applies a 5-step verification protocol to all MS2N units before dispatch review:

1. Visual and mechanical inspection. Shaft runout measurement, bearing play assessment, housing integrity check, connector pin inspection for corrosion or mechanical damage. Units with bent shafts, cracked housings, or corroded connectors are rejected.
2. Winding resistance and insulation testing. Phase-to-phase resistance balance and insulation resistance (megger test) to identify winding degradation. Motors with insulation resistance below acceptable thresholds are not sold as functional units.
3. Encoder verification. Encoder signal integrity is verified where test equipment permits. Battery voltage is checked on battery-backed absolute encoder variants. Firmware version is documented where readable.
4. Electrolytic capacitor assessment. Internal capacitor condition is evaluated on units where access permits. Capacitor aging is a primary failure mode in motors stored for extended periods.
5. Functional run test. Where DriveKNMS test bench compatibility allows, motors are run under no-load conditions and monitored for abnormal noise, vibration, or thermal behavior prior to shipment.

Condition grade (New, Tested Surplus, Refurbished) is documented on the shipment certificate accompanying each unit.

Key Features for System Maintenance

• Drop-in replacement: The MS2N06-D1BNN-CSSG0-NNNNN-NN installs directly into the existing motor mount without mechanical modification. Flange dimensions and shaft geometry are identical to the original installed unit.
• No drive re-parameterization required: Provided the replacement motor carries the same winding code, the existing IndraDrive motor data set (MDS) remains valid. No Rexroth engineer involvement is required for the swap.
• No PLC or HMI changes: The axis behavior from the machine controller's perspective is unchanged. No program modifications, no safety validation re-runs triggered by hardware changes.
• Avoids engineering reconstruction costs: A cross-series or cross-manufacturer motor substitution requires new MDS files, drive firmware compatibility checks, and OEM machine builder sign-off. This unit eliminates all of that.
• Preserves existing safety certifications: Replacing a motor with an identical part number does not trigger CE re-certification requirements in most jurisdictions, unlike a design change substitution.

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Q: Can you support multi-unit or repeat RFQ requests?
A: Yes. Send the model list, target quantity and destination so DRIVEKNMS can review sourcing options and quote the requirement as a project RFQ.

How should discontinued spare motors be stored?
Store in a dry, temperature-stable environment (10–40°C), away from direct sunlight and vibration sources. Rotate shaft quarterly to prevent bearing brinelling. For battery-backed encoder variants, check and replace encoder battery every 2–3 years in storage.
