Bosch Rexroth HMS01.1N-W0054-A-07-NNNN Replacement for IndraDrive M

Product Overview

Bosch Rexroth HMS01.1N-W0054-A-07-NNNN Replacement for IndraDrive M: Seamless Transition from Legacy Servo Drive Systems

When your existing Bosch Rexroth IndraDrive M servo drive reaches end-of-life or becomes unavailable through standard distribution channels, the HMS01.1N-W0054-A-07-NNNN represents the most direct, lowest-risk replacement path available. Rated at 5.4A continuous output current and designed for the IndraDrive M platform, this unit maintains full backward compatibility with the wiring harnesses, SERCOS II/III and PROFIBUS-DP communication stacks, and 24 VDC control voltage infrastructure already installed in your control cabinet. Engineers who have managed legacy HDS, HMD, or HMV series drive systems will find the HMS01.1N-W0054-A-07-NNNN a familiar and immediately deployable solution — no re-engineering of the power stage, no re-parameterization of the axis controller from scratch, and no modification to the existing motor feedback cable routing.

In practice, most retrofit projects involving this unit begin at the control cabinet level. The HMS01.1N-W0054-A-07-NNNN shares the same DIN rail and panel-mount footprint as earlier IndraDrive M variants, meaning the physical installation space in your existing enclosure does not need to be modified. The DC bus connector, brake resistor interface, and motor power output terminals are pin-compatible with the predecessor units, allowing the existing cable assemblies — including shielded motor power cables and resolver or encoder feedback lines — to be reconnected without retermination. This dramatically reduces the risk of wiring errors during commissioning and shortens the overall downtime window to the minimum required for a controlled shutdown, unit swap, and parameter restore.

On the communication side, the HMS01.1N-W0054-A-07-NNNN supports the SERCOS III real-time Ethernet protocol natively, and is also compatible with PROFIBUS-DP fieldbus configurations commonly found in older Bosch Rexroth IndraControl L and IndraControl V controller platforms. If your system architecture uses an IndraMotion MLC or IndraMotion MTX CNC controller as the motion master, the drive will enumerate correctly on the SERCOS ring without requiring a firmware downgrade or protocol bridge. For installations still running SERCOS II fiber-optic rings, a protocol transition module may be required — a consideration that should be evaluated during the pre-replacement audit phase.

The power supply architecture of the IndraDrive M system is another area where compatibility is maintained. The HMS01.1N-W0054-A-07-NNNN is designed to operate within a shared DC bus topology, drawing regulated DC link voltage from an HMV01 or HMV02 supply unit already present in the drive line-up. This means the existing mains transformer, line filter, and regenerative supply module do not need to be replaced as part of this upgrade. The 24 VDC auxiliary supply for the control electronics is sourced from the same PSU already powering the adjacent HMS or HMD axis modules, further simplifying the electrical integration.

From a programming and parameterization perspective, the IndraWorks DS engineering software — the standard tool for Bosch Rexroth IndraDrive commissioning — supports full parameter upload and download for the HMS01.1N-W0054-A-07-NNNN. If a parameter backup was taken from the outgoing drive using IndraWorks or the older DriveTop utility, the majority of axis-specific parameters including current controller gains, velocity loop settings, position feedback configuration, and motor data records can be restored directly. Motor data sets for Bosch Rexroth MSK, MKD, and MHD series servo motors are embedded in the drive firmware, eliminating the need to manually enter motor nameplate data during re-commissioning.

For multi-axis machine tools, packaging lines, or press automation systems where several IndraDrive M axes share a common rack and DC bus, replacing a single HMS01.1N-W0054-A-07-NNNN axis module does not require taking the entire drive line offline. The modular architecture of the IndraDrive M system allows individual axis modules to be hot-swapped at the DC bus level — provided the supply unit HMV and the adjacent HMS or HCS axis modules remain powered and the SERCOS ring is temporarily interrupted only for the affected node. This capability is particularly valuable in high-availability production environments where scheduled maintenance windows are short.

Beyond the drive module itself, a complete migration plan for an IndraDrive M system typically involves reviewing the condition of associated components including the HAS01 accessory module for brake control and I/O expansion, the HLB01 or HLC01 DC bus capacitor modules used for energy buffering, and the NFD or NFE mains filter units installed upstream of the supply module. In systems where the HMS01.1N-W0054-A-07-NNNN is being replaced due to a fault condition rather than planned obsolescence, it is also advisable to inspect the motor feedback cable, the resolver-to-digital converter interface, and the motor thermal sensor wiring for signs of insulation degradation that may have contributed to the original drive fault.

For facilities managing spare parts inventory across multiple Bosch Rexroth IndraDrive M installations, stocking the HMS01.1N-W0054-A-07-NNNN as a critical spare provides insurance against unplanned downtime on axes running MSK or MKD servo motors in the 5A current class. The unit ships fully tested, with all firmware pre-loaded and factory default parameters intact, ready for site-specific commissioning using IndraWorks DS. Each unit is individually inspected prior to dispatch and covered by a 12-month warranty against manufacturing defects and functional failure.

Compatibility Comparison Table

Seamless Upgrade Solutions

A successful IndraDrive M axis replacement rarely involves the drive module alone. In most field retrofit scenarios, the HMS01.1N-W0054-A-07-NNNN is deployed alongside a set of supporting components that together ensure the upgraded axis integrates cleanly into the existing system architecture. The HMV01.1R or HMV02.1R regenerative supply unit provides the regulated DC link voltage for the entire drive line-up and should be verified for adequate capacity when adding or replacing axis modules. Adjacent to the supply unit, HAS01 accessory modules handle brake relay outputs and digital I/O expansion for the axis, and these typically remain in service without modification during a single-axis swap.

On the communication infrastructure side, if the existing SERCOS ring uses fiber-optic cabling for SERCOS II, a transition to SERCOS III Ethernet may require updating the master controller firmware on the IndraMotion MLC or adding a SERCOS III interface card to the IndraControl L controller. PROFIBUS-DP installations using a DP/V1 master on the IndraControl V platform are unaffected, as the HMS01.1N-W0054-A-07-NNNN maintains full DP/V1 slave compatibility. For systems where signal isolation between the drive and field instrumentation is required, DIN-rail-mounted signal isolators or terminal multiplier modules installed in the same control cabinet can be retained without modification.

Motor-side components including the MSK050C or MKD041B servo motors, their associated motor power cables with M23 circular connectors, and the resolver feedback cables with D-sub terminations are all compatible with the HMS01.1N-W0054-A-07-NNNN without retermination. The HLB01 DC bus capacitor module, if present in the drive line-up for energy buffering during rapid deceleration cycles, continues to function normally alongside the replacement axis module. For facilities that also operate HCS01 or HCS02 compact servo drives on the same machine platform, the HMS01.1N-W0054-A-07-NNNN can coexist on the same SERCOS ring or PROFIBUS segment, simplifying spare parts management across mixed drive configurations.

Retrofit Guidance FAQ

Q: Can I reuse the existing motor power and feedback cables?
Yes. The HMS01.1N-W0054-A-07-NNNN uses the same motor power output connector pinout and the same feedback interface as predecessor IndraDrive M axis modules. Existing shielded motor cables and resolver or EnDat feedback cables can be reconnected directly without retermination, provided they pass a standard insulation resistance test prior to recommissioning.

Q: Do I need to update the PLC or motion controller program?
In most cases, no. If the replacement drive is configured with the same axis parameters and motor data set as the outgoing unit, the motion controller program running on the IndraMotion MLC or IndraControl L does not require modification. Parameter restore via IndraWorks DS is the recommended commissioning path.

Q: Is the SERCOS II fiber-optic ring compatible?
The HMS01.1N-W0054-A-07-NNNN natively supports SERCOS III over Ethernet. For systems still using SERCOS II fiber rings, a protocol gateway or master controller firmware update may be required. Please contact our technical team to confirm compatibility with your specific controller revision before ordering.

Q: How much physical space does the replacement require in the control cabinet?
The HMS01.1N-W0054-A-07-NNNN has the same standard IndraDrive M module width and DIN rail mounting pattern as the predecessor unit. No cabinet modification, additional DIN rail space, or busbar extension is required for a like-for-like replacement.
