BOSCH REXROTH: INDRADRIVE M Servo Drives

The Bosch Rexroth Indramat IndraDrive M controllers are a high-performance modular drive system designed for multi-axis industrial automation. It includes separate power supply modules and drive controller modules (inverter drives) that work together to control servo motors with precision and efficiency. IndraDrive M components span the HMV series power supply units and HMS/HMD series inverter drives (single-axis and dual-axis). This flexible architecture allows one supply to power multiple drives, enabling energy sharing between axes and regenerative power feedback to the grid. Wake Industrial specializes in supporting this entire product line – including HMV01, HMV02, HMS01, HMS02, and HMD01 units – with professional repair, replacement, refurbishment, and surplus purchasing services. Our technically trained staff and rich inventory ensure that engineers, plant managers, and business owners can keep their Bosch Rexroth IndraDrive systems running at peak performance.

IndraDrive M Series Overview

IndraDrive M is a modular servo drive solution ideal for complex, multi-axis applications. In a typical IndraDrive M setup, a central HMV (power supply) module generates a DC bus from 3-phase AC mains and feeds multiple HMS (single-axis) or HMD (dual-axis) drive controllers. This modular design reduces hardware redundancy – the combined power rating of the central supply can be lower than the sum of individual drives since not all axes draw peak power simultaneously and braking energy can be reused by other axes​. The result is a more efficient system with energy exchange between motors and generator modes, and the option for regenerative braking (feeding energy back to the mains) for energy savings.

All IndraDrive M components are designed for industrial reliability and performance. They operate on a common DC bus (nominal ~700 V DC) derived from standard mains (typically 3×380-480 VAC) and are built to IP20 protection class for cabinet mounting​. An IndraDrive M system can be configured to precisely match your needs – from a few small axes to a large, coordinated motion system with high-power servo motors. The modular inverter units include slots for plug-in control cards, supporting various interfaces (for encoders, safety circuits, fieldbus/Ethernet communications, etc.), so they integrate seamlessly into modern automation environments​. These drives with robust diagnostics and firmware capabilities, ensuring precise motion control and safe operation in industries ranging from manufacturing and packaging to robotics and machining.

(Note: The IndraDrive M series is distinct from Rexroth’s compact IndraDrive C or Cs series. The IndraDrive C drives are all-in-one HCS series units that include their own power supply. Models like the Rexroth HCS02.1E-W0028 or HCS02.1E-W0070-A-03-NNNN and HCS01.1E-W0054-A-03 are single-axis converters with integrated AC input. Wake Industrial is fully equipped to service those as well, but this page focuses on the modular IndraDrive M line.)

HMV01 & HMV02 Power Supply Units (IndraDrive M Infeed Modules)

The Rexroth HMV series power supply units are the backbone of the IndraDrive M system, converting AC line power into the DC bus voltage that the servo inverters use. Wake Industrial supports both the HMV01 and HMV02 families of IndraDrive M infeed modules, including popular models like HMV01.1E-W0030-A-07-NNNN and HMV01.1R-W0045-A-07-NNNN. Key features and specifications of the HMV units include:

• Power Range: HMV01 units span from 18 kW up to 120 kW output capacity, covering a broad range of industrial needs. For example, the HMV01.1E-W0030-A-07-NNNN is a 30-kW supply module (51 A input) with a ~700 V DC output bus​. The HMV01 series offers both standard rectifier units (denoted by 1E, which dissipate regenerative energy via resistors) and regenerative units (denoted by 1R, capable of feeding braking energy back to the grid). A model like HMV01.1R-W0045-A-07-NNNN provides a regenerative 45 kW capacity infeed​, allowing energy-efficient operation for high-inertia systems. The newer HMV02 supply unit is a compact 15 kW module​, which comes standard with regenerative capability (R designation). This makes the Indramat HMV02 ideal for smaller multi-axis setups or as an energy-saving upgrade.
• Mains Input: 3× 380–480 VAC (+10% tolerance) at 50/60 Hz is the typical input for HMV units​. They draw power from standard industrial mains and generate a stable DC link (nominal ~600–700 V DC under load, up to ~750 V DC no-load) to power the servo drives. HMV02 units feature built-in active front ends for maintaining DC bus stability even with supply fluctuations.
• Regenerative Braking: Both HMV01 (in regenerative versions) and HMV02 support regenerative operation​. This means when connected motors decelerate or brake, the excess energy is either fed back into the facility power grid (in regen mode) or dissipated via an internal/external brake resistor (in non-regen mode). The HMV01 series includes models with integrated braking transistors and contactors depending on the version/size, and HMV02 integrates the braking transistor and resistors by design​. This capability keeps the DC bus voltage regulated and improves energy efficiency.
• Cooling & Protection: All HMV modules use internal air cooling (integrated blower fans) for thermal management​. They are built for cabinet installation with IP20 protection, meaning they are guarded against solid objects but need to be in a control cabinet (protected from water and dust)​. These units also include safety interlocks and monitoring for overtemperature, overvoltage, and leakage current to ensure safe operation of your IndraDrive M system. Typical HMV01 units like the HMV01.1E-W0030 feature status LED/diagnostic interfaces (X31, X32, etc. on the front panel) for easy troubleshooting, and weigh on the order of 20–30 kg for mid-range sizes (the 30-kW unit weighs approx. 25 kg). The smaller HMV02 (15 kW) is lighter (around 9.5 kg) and more compact, easing integration into tight panels​.

By providing a central Indramat HMV infeed, your system benefits from a single point of power control. The HMV manages the inrush current, and it can share energy across all connected axes. Wake Industrial can repair or replace any failing HMV unit quickly – whether your Rexroth HMV01 supply has blown capacitors, or your Rexroth HMV02 needs a refurbishment, we have the expertise and stock to minimize your downtime.

HMS01 & HMS02 Single-Axis Servo Inverters

The Rexroth HMS series are the single-axis inverter drives in the IndraDrive M family. These units take the DC bus power from the HMV supply and output a controlled three-phase AC to a servo motor, providing precise speed and torque control. HMS01 and HMS02 are the two main lines of single-axis drives, covering different power ranges. Wake Industrial services the full range of HMS drives, from small drives for fractional-kilowatt servo motors to large high-current drives for heavy machinery. Some highlights of the HMS single-axis inverters:

Wide Power and Current Range

The HMS01 series supports servo motors from 5.5 kW up to 132 kW output power, making it suitable for both standard and high-power applications. Continuous output currents range roughly from 12 A up to 250 A (with peak currents up to 350 A) depending on the model​. This includes units like the HMS01.1N-W0070 (about 70 A drive) up to very large units delivering over 100 kW for multi-motor gantries or spindle drives. The HMS02 series is targeted at the lower end, covering 5.5 kW to 11 kW per axis, with continuous currents about 14–25 A (peaks ~28–54 A)​. This makes HMS02 drives ideal for smaller servo axes or when a compact form factor is needed. The HMS02.1N-F0110-A-07-S003 is one such case.

Both series run on the common DC bus voltage of approximately 540–750 V DC​, ensuring compatibility with the IndraDrive M supply modules.

Advanced Control & Connectivity

 Each HMS drive is essentially a power section that is controlled by a plug-in control unit (often referred to as an IndraDrive control). These control units (notably the CDB or CSB series, depending on the generation) provide the brains of the drive, with firmware that handles closed-loop servo control and a variety of interfaces. HMS drives feature slots for option modules to interface with encoder feedback, fieldbus networks (SERCOS, PROFIBUS, EtherCAT, etc.), and safety systems (such as safe torque off, per IEC 61508). This modularity means an HMS01 drive can be configured for your specific control architecture easily. For example, you might have an HMS01 drive with a SERCOS III communication card controlling a high-performance IndraDyn servo motor with an absolute encoder – all managed seamlessly by the IndraDrive firmware. The flexibility of the IndraDrive M system is a big advantage for machine builders and system integrators.

Robust Performance

 HMS drives are known for fast control cycles and high dynamics, suitable for precision tasks. They offer configurable switching frequencies to optimize dynamic response and efficiency. For instance, an HMS drive might support 4 kHz or 8 kHz PWM; at higher switching frequencies the continuous current rating is slightly derated due to heat, but you get finer control. (As an example, a drive might handle 20 A continuous at 4 kHz, but 13 A at 8 kHz, as seen in certain HMD dual-axis specs​ – the same principle applies to single-axis units.) In practice, these drives can achieve ±0.01% speed accuracy and very low torque ripple, making them suitable for demanding motion applications. They also incorporate protections for overcurrent, short-circuit, overtemperature, and more, to protect both the drive and the connected motor. Diagnostic codes on the drive’s display help maintenance teams quickly identify issues.

HMD01 Dual-Axis Servo Inverters

The Rexroth HMD01 is the dual-axis inverter in the IndraDrive M lineup. An HMD module contains two independent servo drive channels in one physical unit, which is a space-saving solution for multi-axis systems. Each channel in an HMD can drive a separate motor, with both sharing the common DC bus supply from an HMV module. Wake Industrial supports the HMD series drives, including model HMD01.1N-W0036-A-07-NNNN and all its variants. Notable characteristics of the HMD dual-axis drives include:

• Power and Current Ratings: The HMD01 series covers approximately 3 kW to 7.5 kW per axis output power. In terms of current, each axis can provide around 7 A up to 20 A continuously, with peak currents up to 36 A on short duty cycles​. For example, the HMD01.1N-W0036-A-07-NNNN is rated as 36 A peak current per axis on a 700 V DC bus. It can continuously output about 13–20 A (depending on cooling and switching frequency) per channel​, which corresponds to roughly 5–7 kW continuous motor power per channel. This dual-axis unit effectively packs two drives in one, which simplifies wiring and reduces cabinet footprint for systems like printing machines, packaging lines, or any application with many coordinated servo axes.
• Integration and Features: Just like the single-axis HMS drives, HMD dual-axis inverters have slots for control sections and interface options. One control unit can command both axes, or in some configurations, separate control units can be used for each axis (depending on the exact IndraDrive control firmware and hardware configuration). The HMD drives share the same DC bus (540–750 V DC range) and cooling method (internal air blower) as their single-axis counterparts​. HMD modules also include built-in mains connection components such as pre-charge circuits and filter capacitors, so that they can easily be parallel on the DC bus with other units​. They are built to IP20 and designed for cabinet mounting with proper clearances for airflow.
• Compact Multi-Axis Solution: By using an HMD01 dual drive, machine builders can reduce the number of physical modules. For instance, instead of two separate HMS drives for two axes, one HMD handles both, often at a lower combined cost and with less wiring (only one DC bus connection, one set of DC bus terminals for two motors, etc.). The trade-off is that both axes share the same housing and cooling, so thermal management is crucial. Rexroth designed the HMD with robust cooling and even load distribution in mind – for example, the unit’s total thermal capacity might allow one axis to run at full 20 A continuous while the other is at a lighter load, without overheating. This balance is considered in the product specs. The HMD is ideal for applications like dual-axis gantries, XY tables, or coordinated motions where axis sizes are similar.

If your Rexroth HMD dual-axis drive is experiencing issues, the Wake Industrial team can diagnose and repair it. We maintain HMD01 drive controllers in stock for immediate exchange if needed.
