Bosch Rexroth MS2N04-B0BNN-CSSG1-NNNNN-NN Replacement for IndraDyn S

Product Overview

Bosch Rexroth MS2N04-B0BNN-CSSG1-NNNNN-NN Replacement for IndraDyn S: Seamless Transition & Legacy System Compatibility

The Bosch Rexroth MS2N04-B0BNN-CSSG1-NNNNN-NN is a compact, high-performance servo motor from the IndraDyn S MS2N series, engineered for precision motion control in demanding industrial automation environments. As legacy drive systems age and original equipment manufacturers phase out older model support, facilities running Rexroth IndraDrive, IndraMotion, or earlier DIAX04-based motion platforms increasingly face the challenge of sourcing reliable, specification-matched replacements without triggering costly full-system overhauls.

TOPNLMS specializes in exactly this scenario: supplying tested, ready-to-ship replacement and upgrade solutions for discontinued or hard-to-source Bosch Rexroth servo motors, enabling your engineering team to restore production continuity with minimal downtime and zero compromise on performance.

Seamless Upgrade Solutions

Migrating from an aging Rexroth motion system to the MS2N04-B0BNN-CSSG1-NNNNN-NN rarely involves swapping the motor alone. A successful retrofit typically requires coordinating several interdependent components across the drive cabinet and control architecture.

On the drive side, the MS2N04 is designed to operate with Bosch Rexroth IndraDrive C series converters such as the HCS02.1E and HCS03.1E, as well as IndraDrive M supply and axis modules (HMS01, HMD01). If your existing cabinet runs an older HDS or DKS drive, upgrading to a current IndraDrive platform alongside the motor replacement will unlock SERCOS III and EtherCAT communication capabilities, eliminating the protocol translation overhead common in legacy SERCOS II or analog command architectures.

The feedback cable between the MS2N04 motor and the drive must match the CSSG1 encoder specification. Rexroth INK0602 or INK0603 series motor feedback cables are the standard choice for this encoder variant. Reusing legacy resolver cables is not compatible — this is one of the most common wiring errors during MS2N retrofits and should be verified before commissioning.

For axis control, the MS2N04 integrates directly with Bosch Rexroth IndraMotion MLC and IndraMotion MTX CNC controllers via the IndraDrive axis interface. If the existing machine runs an older DIAX04 or Ecodrive03 motion controller, a controller migration to the IndraMotion MLC L25 or L45 platform is recommended to take full advantage of the MS2N04’s encoder resolution and dynamic response characteristics.

Power supply integrity is critical. The MS2N04’s winding (BNN designation) is matched to a specific DC bus voltage range supplied by the IndraDrive power section. Ensure the HMV01 or HMV02 supply module is correctly sized for the combined axis load. Undersized supply modules are a frequent cause of drive fault codes (F2xxx series) during initial commissioning after a motor swap.

On the I/O and safety side, if the machine uses a Rexroth SafeMotion or Safe Torque Off (STO) function, verify that the safety wiring to the drive’s X41 safety connector is preserved and re-validated after the motor replacement. The MS2N04 supports STO at the drive level — no additional safety encoder module is required for basic STO functionality.

Terminal and connector compatibility should also be reviewed. The MS2N04 uses Rexroth standard power connectors (INP0x series) and feedback connectors (INS0x series). If the existing cable harness uses older MS2 connectors, adapter sets or new cable assemblies may be required. TOPNLMS can advise on connector compatibility based on your existing cable part numbers.

Finally, for machines where the MS2N04 drives a gearbox or direct-drive load, confirm that the shaft diameter, key slot, and flange centering bore match the mechanical coupling. The smooth shaft (NN suffix) variant requires a friction-fit or clamping hub — not a keyed coupling — which differs from some legacy MS2 shaft configurations.

Retrofit Guidance FAQ

Q: Can I reuse my existing motor power cable from the legacy MS2 motor?
A: In most cases, yes — provided the connector type on the motor end matches the MS2N04’s radial power connector (INP series). Verify the cable cross-section is rated for the motor’s peak current. If the legacy cable uses an axial connector, a new cable or adapter is required.

Q: Do I need to re-parameterize the drive after replacing the motor?
A: Yes. The IndraDrive must be loaded with the correct motor data set (MDS) for the MS2N04-B0BNN-CSSG1-NNNNN-NN. This is done via IndraWorks DS or IndraWorks Engineering software. The motor data file is available from Bosch Rexroth’s parameter database. Failure to update the MDS will result in incorrect current limits and encoder scaling.

Q: Is the MS2N04 compatible with SERCOS II drives, or only SERCOS III?
A: The MS2N04 motor itself is protocol-agnostic — communication protocol is determined by the IndraDrive firmware and hardware variant. HCS02 and HMS01 drives support both SERCOS II and SERCOS III depending on the firmware version. Confirm your drive’s firmware level before assuming protocol compatibility.

Q: Will the MS2N04 fit in the same physical space as my existing motor?
A: The MS2N size 04 frame maintains the same flange dimensions and overall length as the equivalent MS2 size 04 motor. In most installations this is a direct bolt-in replacement. However, if the legacy motor had a holding brake (B1 or B2 suffix), the MS2N04-B0 (no brake) will be slightly shorter — verify that the coupling and load alignment are not affected.

Q: What is the lead time for the MS2N04-B0BNN-CSSG1-NNNNN-NN?
A: TOPNLMS maintains stock of high-demand IndraDyn S MS2N series motors. In-stock units ship within 1–3 business days from Xiamen. For urgent production-down situations, contact us directly at [email protected] or +86 18359293191 for expedited handling.

Q: Can TOPNLMS supply the matching IndraDrive and cables as a complete retrofit kit?
A: Yes. We can source and supply matched IndraDrive C/M axis modules, motor feedback cables, power cables, and connector sets as a coordinated package. Provide your existing drive part numbers and we will confirm compatibility before shipment.

Warranty Assurance

Every MS2N04-B0BNN-CSSG1-NNNNN-NN supplied by TOPNLMS is covered by a 12-month warranty from the date of shipment. Our pre-shipment inspection process includes visual inspection, encoder signal verification, winding resistance measurement, and insulation resistance testing. Units that do not meet specification are quarantined and not shipped.

In the event of a warranty claim, TOPNLMS provides a replacement unit or full refund within the warranty period. Our technical team is available to assist with fault diagnosis remotely — in many cases, drive fault codes and commissioning logs allow us to determine whether a reported fault is motor-related or drive/parameter-related before a return is initiated, saving your team time and avoiding unnecessary shipping.

Warranty coverage includes manufacturing defects, encoder failure, and winding faults under normal operating conditions. It does not cover damage resulting from incorrect installation, mismatched drive parameterization, overvoltage events, or mechanical overload. Our pre-sale technical support is designed to prevent these scenarios — we encourage customers to share their drive configuration and application details before ordering.

TOPNLMS ships globally from Xiamen, China, with DHL Express, FedEx International Priority, and UPI freight options. Export documentation, commercial invoices, and packing lists are provided with every shipment. For customers requiring CE declarations or material certificates, these can be provided upon request.
