Bosch Rexroth MS2N06-D1BNN-CSSG0-NNNNN-NN Replacement for IndraDyn S

Product Overview

Bosch Rexroth MS2N06-D1BNN-CSSG0-NNNNN-NN Replacement for IndraDyn S: Seamless Transition from Legacy Drive Systems

Upgrading or replacing a servo motor in an active production environment demands precision, compatibility assurance, and minimal disruption to ongoing operations. The Bosch Rexroth MS2N06-D1BNN-CSSG0-NNNNN-NN is a synchronous servo motor from the IndraDyn S series — a platform widely deployed across CNC machining centers, packaging lines, injection molding machines, and general-purpose motion control systems. Whether you are retiring an end-of-life drive axis, recovering from an unexpected motor failure, or executing a planned modernization of an older Rexroth drive system, this unit is engineered to integrate directly into your existing architecture with minimal re-engineering effort.

The MS2N06-D1BNN-CSSG0-NNNNN-NN belongs to the compact IndraDyn S frame-size 06 family, designed for applications requiring high torque density in a space-constrained control cabinet or machine axis. Its encoder interface and power connector pinout are fully compatible with the Bosch Rexroth IndraDrive family — including IndraDrive Cs (HCS01), IndraDrive C (HCS02/HCS03), and IndraDrive M (HMS/HMD) drive controllers — allowing direct substitution without rewiring the motor cable or modifying the drive parameter set beyond axis-specific tuning values.

For facilities migrating from older Rexroth DIAX04 or Ecodrive03 drive systems, the MS2N06 series represents a forward-compatible upgrade path. The motor’s resolver or multi-turn absolute encoder option (depending on the specific variant suffix) is recognized natively by IndraDrive firmware, and the SERCOS III or EtherCAT communication layer on the drive side remains unchanged. Engineers performing this type of retrofit typically also replace the associated HCS02.1E or HMD01.1N drive module, the DST01 or DSC01 safety module, and the associated MSK or MKD legacy motor that is being retired — all of which can be sourced alongside this unit to complete the axis replacement in a single procurement cycle.

Physical installation follows the standard IEC 72 flange and shaft dimensions for the IndraDyn S frame-06 class. The motor mounts directly to the existing gearbox or machine coupling without machining modifications in the vast majority of retrofit scenarios. Cooling is via natural convection (IC410 class), eliminating the need for external fan wiring or coolant circuit integration that some legacy motors required. The IP65 protection rating ensures suitability for environments with coolant mist, swarf, or moderate wash-down exposure.

From a wiring standpoint, the power cable connector (Rexroth INK0xxx series) and the feedback cable connector (IKS4xxx or IKG4xxx series) are standard across the IndraDyn S platform. If your existing cable harness was routed for an MSK060 or MSK061 motor, the MS2N06 uses the same connector family, and in many cases the existing cables can be reused without modification — a significant labor saving during a time-critical breakdown replacement. The brake connector (if the variant includes a holding brake) also follows the standard Rexroth 24 VDC brake wiring convention.

For system integrators managing a broader axis modernization project, the MS2N06-D1BNN-CSSG0-NNNNN-NN is typically deployed alongside complementary components including the Rexroth IndraControl L45 or L65 CNC controller, the HAS02 or HAS05 accessory module for axis expansion, the NFD03 mains filter for EMC compliance, and the HNF01 or HNL01 line filter/choke assembly. Power supply modules such as the HMV01 or HMV02 regenerative supply unit are also commonly part of the same cabinet upgrade, ensuring the DC bus architecture supports the updated motor’s peak current demands.

All units supplied by TOPNLMS are sourced from verified industrial channels, inspected prior to dispatch, and shipped with full documentation. Stock availability is confirmed at time of order, and standard lead time for in-stock units is 3–7 business days to most destinations. Express shipping options are available for breakdown emergencies.

Seamless Upgrade Solutions

A complete axis modernization using the MS2N06-D1BNN-CSSG0-NNNNN-NN typically involves more than the motor itself. During the retrofit process, engineers commonly address the drive controller — replacing an aging HCS02.1E-W0054 or HMD01.1N-W0012 with a current-generation IndraDrive C or M unit to match the motor’s updated encoder protocol. The DC bus supply is often upgraded simultaneously, with the HMV01.1R or HMV02.1R regenerative power supply replacing older non-regenerative units to improve energy efficiency and reduce braking resistor heat load in the control cabinet.

On the signal and safety side, the DST01.1 or DSC01.1 safety module is frequently replaced to meet current SIL 2 / PLd requirements, particularly in machinery directive compliance projects. The IndraControl L45 or XM22 motion controller may also be updated as part of the same project scope, with the existing SERCOS fiber ring or EtherCAT topology preserved to minimize re-commissioning effort on the remaining axes.

For wiring infrastructure, the INK0602 power cable and IKS4039 feedback cable are the most common cable assemblies used with this motor frame size and are available as pre-assembled Rexroth-standard lengths. Terminal modules such as the Rexroth HAS02.1 or third-party DIN-rail signal isolators are used where legacy analog setpoint signals must be bridged into the new digital drive architecture. In multi-axis cabinets, the HAS05 axis expansion module and associated DC bus bars are also part of the standard bill of materials for a full-cabinet retrofit.

Retrofit Guidance FAQ

Q: Can I reuse my existing motor power and feedback cables?
A: In most cases, yes. The MS2N06 uses the standard Rexroth INK0xxx power connector and IKS4xxx/IKG4xxx feedback connector, which are shared across the IndraDyn S platform. If your existing cables were routed for an MSK060 or MSK061, they are directly compatible. Verify cable length and shielding integrity before reuse.

Q: Do I need to modify my drive parameters after replacement?
A: If replacing a like-for-like IndraDyn S motor (same frame, same encoder type), the existing motor data set (MDS) in the IndraDrive can typically be reloaded. If migrating from a DIAX04 or Ecodrive03 system, a full axis commissioning using IndraWorks DS or IndraWorks Engineering is required to load the correct motor data file and re-tune the velocity and position control loops.

Q: Is the physical mounting footprint identical to the MSK060?
A: Yes. The MS2N06 shares the IEC 72 frame-06 flange dimensions and shaft diameter with the MSK060 family, allowing direct bolt-on replacement in the vast majority of machine designs without mechanical modification.

Q: What communication protocol does this motor support?
A: The MS2N06 motor itself is protocol-agnostic — communication is handled at the drive controller level. The IndraDrive platform supports SERCOS III and EtherCAT natively. If your existing system uses SERCOS II (fiber), a drive firmware update or drive replacement may be required to migrate to SERCOS III copper or EtherCAT.

Q: Can this motor be used in a cabinet with limited space?
A: The frame-06 form factor is one of the most compact in the IndraDyn S range. Natural convection cooling (IC410) eliminates the need for external fan assemblies, further reducing the installation envelope. Verify the motor length (L1 dimension) against your axis travel and coupling clearance before installation.

Q: What if the replacement motor does not perform identically after installation?
A: TOPNLMS provides a 12-month warranty covering manufacturing defects and performance deviations from published specifications. If the unit does not perform as expected after correct installation and commissioning, contact our technical support team for replacement or credit authorization.
