Rexroth HMS01.1N-W0110-A-07-NNNN Replacement for IndraDrive: Smooth Migration from Legacy Servo Systems
The Bosch Rexroth HMS01.1N-W0110-A-07-NNNN is a high-performance IndraDrive M axis inverter rated at 11 kW continuous output power, engineered for demanding multi-axis servo applications across industrial automation, machine tool, press, and packaging lines. As Rexroth progressively phases out earlier IndraDrive C (HCS series) and legacy DIAX04 / ECODRIVE03 platform variants, facilities operating aging servo systems face mounting pressure to source verified replacement units or execute structured migration plans. This page is dedicated to engineers and procurement teams seeking a tested, immediately shippable HMS01.1N-W0110-A-07-NNNN — whether as a direct spare, a drop-in replacement for a failed axis module, or as the cornerstone of a broader control system modernization project.
The HMS01.1N-W0110-A-07-NNNN belongs to the IndraDrive HMS (High-performance Multi-axis Supply) series, which operates on a shared DC bus architecture alongside the HMD01 single-axis inverter and the HMV01 / HMV02 regenerative supply modules. In a typical IndraDrive M multi-axis cabinet, the HMS01.1N-W0110-A-07-NNNN mounts on the same DC bus rail as other HMS or HMD inverter modules, all powered by a shared HMV01.1R or HMV01.1E supply unit. This shared-bus topology means that replacing a single failed HMS01.1N-W0110-A-07-NNNN does not require reconfiguring the entire drive cabinet — the replacement unit slots into the existing mechanical rail, reconnects to the DC bus capacitor bar, and interfaces with the existing SERCOS II fiber-optic ring or PROFIBUS DP network without rewiring motor power cables or encoder feedback lines, provided the motor type and encoder protocol remain unchanged.
For facilities migrating from an older IndraDrive C (HCS02 or HCS03) single-axis topology to a multi-axis HMS architecture, the HMS01.1N-W0110-A-07-NNNN offers a significant reduction in cabinet footprint. The HMS series shares the same 270 mm depth profile as HCS02 and HCS03 units, and the motor power connector pinout is compatible with standard Rexroth MSK servo motor cables — meaning existing motor wiring harnesses can typically be reused without modification. The encoder interface supports both Hiperface and EnDat 2.1 protocols via the standard X8 encoder connector, ensuring compatibility with MSK030, MSK040, MSK050, MSK060, and MSK070 series servo motors already installed in the machine.
Communication integration is a critical concern during any servo drive replacement or upgrade. The HMS01.1N-W0110-A-07-NNNN supports SERCOS II (fiber-optic, 2 Mbit/s and 4 Mbit/s) and PROFIBUS DP (up to 12 Mbit/s) as its primary fieldbus options, as indicated by the “-A-07” option code in the part number. This dual-protocol capability allows the unit to integrate directly into existing Siemens SIMATIC S7 or Rexroth IndraMotion MLC controller architectures without requiring a gateway or protocol converter. When replacing a failed axis module in a SERCOS II ring, the new HMS01.1N-W0110-A-07-NNNN simply takes the same SERCOS address as the failed unit — configured via the onboard rotary switch — and the IndraMotion MLC or IDS controller recognizes it automatically upon the next ring initialization cycle.
Firmware and parameter migration is straightforward for most replacement scenarios. The HMS01.1N-W0110-A-07-NNNN runs IndraDrive firmware (MPH, MPB, or MPD depending on the application package), and existing axis parameters stored in the controller’s non-volatile memory or in an IndraWorks DS project file can be downloaded to the replacement unit via the SERCOS or PROFIBUS interface, or directly through the X2 serial service interface using a standard Rexroth IKS4044 programming cable. This eliminates the need for manual parameter re-entry and significantly reduces commissioning time during an emergency replacement — a critical advantage when minimizing production downtime is the primary objective.
For facilities planning a phased migration from a legacy Rexroth DIAX04 HDS or ECODRIVE03 FCS drive system to the IndraDrive platform, the HMS01.1N-W0110-A-07-NNNN is a natural target endpoint. The DIAX04 and ECODRIVE03 drives use an older SERCOS I interface and proprietary parameter structures that are not directly compatible with IndraDrive firmware. However, Rexroth’s IndraWorks migration tools provide parameter mapping utilities that translate DIAX04 axis parameters into IndraDrive-compatible format, and the motor power and encoder wiring is physically compatible with the same MSK motor families. In practice, a DIAX04-to-HMS01 migration typically requires only firmware re-parameterization and a SERCOS address reassignment — the motor cables, encoder cables, and cabinet mounting hardware can all be reused, keeping retrofit costs and downtime to a minimum.

Seamless Upgrade Solutions
A successful HMS01.1N-W0110-A-07-NNNN installation rarely involves the axis inverter alone. In a complete IndraDrive M multi-axis cabinet, the axis module operates in conjunction with several interdependent components that must be verified or replaced as part of the migration. The HMV01.1R-W0045 or HMV01.1E-W0120 regenerative supply module provides the shared DC bus voltage that powers all HMS and HMD axis inverters in the cabinet — if the supply module is aging or undersized for the expanded axis count, it should be assessed alongside the HMS01.1N-W0110-A-07-NNNN replacement. Similarly, the HMD01.1N single-axis inverter modules sharing the same DC bus rail must be confirmed compatible with the firmware revision running on the new HMS unit to avoid SERCOS ring initialization conflicts.
On the I/O and signal conditioning side, the HMS01.1N-W0110-A-07-NNNN’s digital and analog I/O is typically supplemented by an IndraDrive I/O extension module or an external Rexroth Inline I/O terminal block connected via PROFIBUS DP. For applications requiring signal isolation between the drive’s 24 VDC I/O and field-level sensors, a DIN-rail-mounted signal isolator or relay module is recommended to protect the drive’s I/O interface from ground loops or voltage transients common in retrofit environments. The X14 and X31 I/O connectors on the HMS01.1N-W0110-A-07-NNNN use the same pinout as other IndraDrive M series modules, so existing I/O wiring looms can be transferred directly without re-termination.
For the control layer, the IndraMotion MLC L25 or L45 motion controller communicates with the HMS01.1N-W0110-A-07-NNNN over the SERCOS II fiber ring. If the existing controller is an older CSB01 or CDB01 variant, firmware compatibility with the HMS01 firmware version should be verified in the Rexroth compatibility matrix before commissioning. In PROFIBUS-based architectures, the Siemens SIMATIC S7-300 or S7-400 PLC with a CP342-5 or CP443-5 PROFIBUS master module communicates directly with the HMS01.1N-W0110-A-07-NNNN using the standard Rexroth GSD file. No additional hardware gateway is required between the PLC and the drive, which simplifies the cabinet wiring and reduces commissioning time.
Power supply integrity is equally important during a retrofit. The 24 VDC control voltage supply for the HMS01.1N-W0110-A-07-NNNN’s logic and I/O circuits is typically provided by a dedicated DIN-rail power supply unit — a PSR or PSS series unit from Phoenix Contact, or equivalent — mounted in the same cabinet. If the existing 24 VDC supply is shared with other control components, verify that its rated output current is sufficient to support the additional HMS01 logic load without voltage droop during startup transients.
HMI integration is typically handled through the same PROFIBUS or Ethernet network that connects the controller to the drive. A Rexroth IndraControl VEP or VPP operator panel, or a third-party HMI connected via OPC-UA or Modbus TCP through the controller, can display drive status, fault codes, and axis position data without any direct connection to the HMS01.1N-W0110-A-07-NNNN itself. This architecture simplifies the physical wiring in the control cabinet and reduces the number of cable entries through the cabinet door, which is a practical advantage in space-constrained retrofit installations.
For applications where the HMS01.1N-W0110-A-07-NNNN is being integrated into a new or expanded machine section alongside existing axes, the SERCOS II fiber ring topology allows the new axis to be inserted into the ring without disrupting the other axes — provided the ring is re-initialized after the new module is connected. The fiber-optic SERCOS cables (IKO0xxx series) between modules should be inspected for bend radius compliance and connector cleanliness before commissioning, as contaminated or kinked fiber connectors are a common source of SERCOS ring faults in retrofit installations.
Retrofit Guidance FAQ
Q: Can I replace a failed HMS01.1N-W0110-A-07-NNNN without re-parameterizing the axis from scratch?
A: Yes, in most cases. If the IndraMotion MLC or SIMATIC S7 controller retains the axis parameter set in its non-volatile memory or in an IndraWorks DS project backup, the parameters can be downloaded to the replacement unit via SERCOS II or the X2 serial interface using an IKS4044 cable. The SERCOS address must be set to match the failed unit’s address using the onboard rotary switch before powering up the ring.
Q: Do I need to replace the motor power cables when installing the HMS01.1N-W0110-A-07-NNNN?
A: No. The HMS01.1N-W0110-A-07-NNNN uses the same motor power connector pinout as other IndraDrive M series axis modules. Existing IKW or IKS motor power cables rated for the motor’s current and voltage can be reused without modification, provided they are in good condition and correctly shielded.
Q: Is the HMS01.1N-W0110-A-07-NNNN compatible with PROFIBUS DP masters from Siemens, Schneider, or ABB?
A: Yes. The PROFIBUS DP interface is fully compliant with IEC 61158 and is compatible with any certified PROFIBUS DP master, including Siemens SIMATIC S7, Schneider Modicon Quantum, and ABB AC500 PLCs. The Rexroth GSD file must be loaded into the PLC’s hardware configuration tool to define the drive’s I/O data structure.
Q: What is the physical installation space requirement?
A: The HMS01.1N-W0110-A-07-NNNN has a standard IndraDrive M form factor with 270 mm depth and mounts on the standard Rexroth drive rail. The 11 kW variant typically occupies a 100 mm wide slot. Verify the available slot width in the existing cabinet before ordering if replacing a different power-class unit.
Q: Can the HMS01.1N-W0110-A-07-NNNN operate on a SERCOS II ring alongside older HMS01.1N units with different firmware versions?
A: Mixed firmware versions on the same SERCOS ring are generally supported, but Rexroth recommends aligning all axis modules to the same firmware revision to avoid potential ring synchronization issues. Firmware can be updated via IndraWorks DS over the SERCOS interface or via the X2 serial port.
Q: What safety precautions are required when replacing an axis module in a live multi-axis cabinet?
A: The entire DC bus section must be de-energized and the bus capacitors fully discharged before removing or installing any HMS or HMD axis module. The HMV supply module’s DC bus discharge resistor typically discharges the bus within 5–10 minutes after mains disconnection. Always verify bus voltage with a calibrated meter before touching any bus bar connections.
Q: How do I verify the HMS01.1N-W0110-A-07-NNNN is a genuine, specification-matched unit before installation?
A: Check the nameplate on the unit’s front panel for the full part number, hardware revision (HW), and serial number. Cross-reference the hardware revision against the Rexroth compatibility matrix for your firmware version. TOPNLMS provides the serial number and hardware revision in the shipment documentation so you can verify before the unit arrives on site.
