Rexroth HSM01.1-FW Retrofit Memory Card for Legacy Systems

Rexroth HSM01.1-FW Retrofit Memory Card for Legacy Systems

The Bosch Rexroth HSM01.1-FW is a firmware and parameter storage memory card designed for use within the IndraDrive and IndraDyn servo drive platform. As legacy automation systems age and original spare parts become increasingly scarce, the HSM01.1-FW plays a critical role in sustaining operational continuity across aging production lines, retrofit control cabinets, and modernization projects where full drive replacement is not yet feasible or cost-effective. This module stores drive firmware, axis parameters, and application-specific configuration data, enabling engineers to restore a failed drive to its last known operational state without requiring a full recommissioning cycle from scratch.

For maintenance teams managing end-of-life Rexroth IndraDrive systems, the HSM01.1-FW provides a reliable path to extend the service life of existing servo axes. Whether the goal is to replace a failed memory card in a DKC01.1 or DKC02.1 drive controller, restore a corrupted firmware image in an HDS03.2-W075N spindle drive, or migrate stored parameters from a decommissioned axis to a refurbished replacement unit, the HSM01.1-FW is the foundational component that makes non-disruptive recovery possible.

Retrofit Planning for Existing Automation Systems

Successful integration of the HSM01.1-FW into a retrofit project requires a structured approach that accounts for the full scope of the drive system architecture. Before removing the failed or obsolete memory card, engineers should document the existing drive configuration using the Rexroth IndraWorks DS engineering software, exporting all axis parameters, encoder data, and application-specific settings to a backup file stored on a separate medium.

In a typical IndraDrive retrofit scenario, the HSM01.1-FW is installed in a DKC01.1 or DKC02.1 drive controller that forms part of a multi-axis SERCOS ring. The memory card holds the firmware image and parameter set that defines how the drive responds to motion commands from the master controller — often a Rexroth IndraMotion MLC or a third-party PLC communicating over PROFIBUS-DP or EtherCAT. When replacing the card, it is essential to verify that the firmware version stored on the new HSM01.1-FW is compatible with the hardware revision of the host drive. Mismatched firmware can result in fault codes at startup, incorrect encoder feedback processing, or communication link failures that prevent the axis from being recognized by the motion controller.

Power supply integrity is another critical checkpoint. The HMV01.1E-W0030 mains supply module or equivalent DC bus supply must be verified to deliver stable voltage within the drive’s operating range before the new memory card is inserted. Voltage fluctuations during the card initialization sequence can corrupt the firmware load process and render the card unreadable. Similarly, the CSB01.1C control section board and CSE01.1-SE encoder evaluation module should be inspected for signs of wear or contamination, as these components interact directly with the memory card during the boot sequence.

For systems that include an HMS01.1-W communication module handling PROFIBUS or EtherCAT connectivity, the node address and baud rate settings stored on the HSM01.1-FW must match the network configuration defined in the PLC project. After card replacement, the communication link should be verified using the network diagnostic tools available in the PLC programming environment before the axis is enabled. I/O mapping and module addressing should also be confirmed, particularly in systems where the IndraDrive axes are integrated into a distributed I/O architecture alongside third-party terminal modules.

HMI screens configured to display axis status, fault codes, and parameter values via the BTV06.1HN-RS operator panel or equivalent interface should be tested after the retrofit to confirm that all data tags are resolving correctly. In some cases, HMI tag addresses are linked to specific parameter numbers that may differ between firmware versions, requiring a review of the HMI project before returning the system to production.

For multi-axis systems using IndraDrive Cs compact drives or IndraDrive Mi integrated motor-drive units, the HSM01.1-FW retrofit procedure follows the same general sequence but may involve additional steps related to motor encoder data storage and axis-specific calibration. The FWA-ECODR3 firmware package should be confirmed as the correct base firmware for the target drive family before programming the replacement card.

Downtime Control During System Migration

Minimizing unplanned downtime during an HSM01.1-FW replacement is achievable through careful pre-migration preparation. The most effective strategy is to pre-program the replacement memory card with the correct firmware version and parameter set before the maintenance window begins. Using IndraWorks DS, engineers can load the backed-up parameter file onto the new card while the production line is still running, so that the physical swap during the maintenance window is reduced to a simple card exchange and a brief drive restart sequence.

Where the drive supports hot-plug card insertion, the replacement can be performed without de-energizing the entire control cabinet, reducing the impact on adjacent axes and shared infrastructure such as the DC bus supply and cooling systems. However, the axis being serviced must be safely stopped and its enable signal removed before the card is touched. The safety relay circuit and any associated STO (Safe Torque Off) wiring should be verified to be in the safe state before any physical intervention on the drive.

After the new HSM01.1-FW is inserted and the drive restarts, the commissioning engineer should monitor the drive’s status LEDs and fault display for any initialization errors. The SERCOS or EtherCAT communication link should be confirmed as active within the expected startup time. If the drive enters a fault state, the fault code should be recorded and cross-referenced against the IndraDrive troubleshooting documentation before any further action is taken. In most cases, a successful card swap results in the drive returning to its previous operational state within a single restart cycle, with no changes required to the PLC program or HMI configuration.

Pre-shipment functional testing of the HSM01.1-FW ensures that the card is verified to initialize correctly and hold its firmware image before it reaches the customer site, further reducing the risk of extended downtime caused by a defective replacement part.

Retrofit Support FAQ

Q: Is the HSM01.1-FW a direct replacement for the original Bosch Rexroth part?
A: Yes. The HSM01.1-FW supplied through NINERMAS is sourced to match the original Rexroth specification. Each unit is pre-tested to confirm correct initialization and firmware storage function. Customers are advised to confirm the firmware version required for their specific drive hardware revision before ordering.

Q: What pre-shipment testing is performed on the HSM01.1-FW?
A: Each HSM01.1-FW undergoes functional verification prior to dispatch, including card initialization testing and firmware image integrity checks. Units are shipped with a 12-month warranty covering manufacturing defects and functional failures under normal operating conditions.

Q: Do I need to re-wire the drive after replacing the HSM01.1-FW?
A: No wiring changes are required for a like-for-like memory card replacement. The HSM01.1-FW is a plug-in module that interfaces with the drive through the card slot on the front panel. All power, signal, and communication wiring to the drive remains unchanged. However, if the retrofit involves upgrading to a different drive model or communication protocol, terminal wiring and cable routing should be reviewed against the new drive’s connection diagram.

Q: What is the warranty coverage and how is it supported?
A: The HSM01.1-FW is covered by a 12-month warranty from the date of shipment. Warranty claims are handled directly through NINERMAS. In the event of a confirmed defect, a replacement unit will be dispatched after the faulty item is returned and inspected. Customers with urgent production requirements are encouraged to contact the NINERMAS sales team to discuss advance replacement options.
