Technical Dossier
The Bosch Rexroth HDD02.2 series represents a generation of AC servo drives developed under the DIAX04 drive platform, engineered for high-precision motion control in continuous-duty industrial environments. These drives are deployed across global heavy industry sectors including petrochemical processing plants, nuclear power auxiliary systems, offshore drilling rigs, steel rolling mills, and large-scale automated assembly lines. The HDD02.2 family operates within the DIAX04 firmware ecosystem, supporting multiple motion function packages (ELS, HSM, HDS, etc.) selectable via firmware variant codes. Their modular firmware architecture allows a single hardware unit to be reconfigured for electronic gearing, spindle positioning, or velocity control without hardware replacement. Installed base across Europe, Asia-Pacific, and the Americas remains substantial, making long-term spare parts availability a critical operational concern for maintenance engineers.
The HDD02.2 series is the second-generation hardware revision of the HDD platform within Bosch Rexroth's DIAX04 drive family. The original HDD01.x series established the base analog and digital interface architecture; the HDD02.x revision introduced enhanced current regulation bandwidth, improved EMC shielding topology, and expanded firmware compatibility with the FWA-DIAX04 firmware generation. Key firmware variants include ELS (Electronic Line Shaft), HSM (High-Speed Machining), HDS (Hydraulic Drive Simulation), and MP (Multi-Purpose), each encoded in the firmware part number suffix (e.g., FWA-DIAX04-ELS-05VRS-MS). The -MS suffix denotes the MultiSercos interface variant, enabling synchronous multi-axis coordination over SERCOS fiber-optic ring networks. Compatibility constraints are strict: firmware version must match the hardware revision index and the connected motor encoder type (resolver, EnDat, or Hiperface). As of the mid-2010s, Bosch Rexroth transitioned its primary servo platform to the IndraDrive (HCS/HMS/HMD) family, placing the entire HDD02.2 series in the mature/end-of-life phase. Replacement cross-references map HDD02.2 units to IndraDrive C (HCS02.1) or IndraDrive M (HMS01.1) depending on power class and interface requirements. For sites unable to migrate, lifecycle extension through certified refurbished HDD02.2 units and firmware media preservation is the standard maintenance strategy.
The following SKUs represent verified, commonly stocked models within the HDD02.2 series, classified by power rating and firmware function package. Each unit requires a matched FWA-DIAX04 firmware module (sold separately or pre-loaded).
Servo Drive Units — ELS (Electronic Line Shaft) Firmware Variants
Servo Drive Units — HSM (High-Speed Machining) Firmware Variants
Servo Drive Units — MP (Multi-Purpose) Firmware Variants
Servo Drive Units — Analog Interface Variants
The HDD02.2 series reached end-of-active-production status as Bosch Rexroth consolidated its servo drive portfolio around the IndraDrive platform. Standard distribution channels no longer carry new stock for most HDD02.2 variants. DriveKNMS maintains a dedicated inventory of tested, refurbished, and new-surplus HDD02.2 units sourced from decommissioned machinery, factory overstock, and authorized secondary market channels. For firmware media (FWA-DIAX04-* modules), DriveKNMS holds physical firmware cards and can supply matched firmware-hardware sets to eliminate compatibility risk. Lead times for common variants (W015N, W020N, W040N) are typically 3–10 business days. For high-power variants (W075N and above) or rare firmware combinations, sourcing timelines are quoted individually. All units are supplied with a test report and 12-month operational warranty. Cross-reference support to IndraDrive equivalents is available on request for customers planning platform migration.
HDD02.2 drives incorporate a multi-layer internal architecture: power stage (IGBT module + gate driver board), control board (DSP + FPGA), interface board (SERCOS or analog), and firmware module socket. DriveKNMS applies a structured test protocol specific to this architecture. Power stage verification uses a programmable AC source to confirm rated current delivery (15A / 20A / 40A / 75A) under resistive and inductive load conditions. Control board diagnostics include oscilloscope-based verification of PWM output symmetry, encoder feedback signal integrity (resolver excitation frequency and amplitude, EnDat clock/data timing), and SERCOS ring communication at 2Mbps and 4Mbps baud rates. Firmware module authentication confirms version code, checksum, and boot sequence completion. Final functional test runs the drive through velocity loop, position loop, and electronic gearing modes using a matched Rexroth MKD or MHD motor on a dynamometer bench. Units failing any stage are quarantined and not shipped. Test records are retained and available to customers on request.
