Bosch Rexroth CLC-D02.2 Positioning Control Card – Obsolete Indramat Spare Part

When a CLC-D02.2 positioning control card fails in a production environment, the consequences are not limited to a single axis going offline. In legacy Bosch Rexroth Indramat motion control architectures, this card is the computational core of closed-loop positioning. Its failure cascades: the drive controller loses position feedback processing, the axis faults out, and the entire cell stops. For manufacturers still operating Indramat CLM or CLC-series controllers — systems that were engineered to run for decades — sourcing a replacement card through OEM channels is no longer possible. Bosch Rexroth discontinued this product line years ago. A forced migration to a current-generation drive platform carries engineering costs that routinely exceed $200,000 USD per axis group when PLC reprogramming, mechanical reconfiguration, and production downtime are factored in. DriveKNMS maintains verified stock of the CLC-D02.2. This is not a commodity listing. It is a targeted solution for facilities that have made a deliberate decision to protect their capital investment in existing automation infrastructure.

Technical Specifications

Note: Specific electrical parameters (voltage ratings, current specs) are confirmed individually upon request and verified against the unit's hardware revision label. No parameters are published here that have not been physically verified — accuracy in obsolete drive components is a safety matter.

Solving the Discontinued Hardware Crisis

The Bosch Rexroth Indramat CLC and CLM controller family was deployed extensively throughout the 1980s and 1990s in European and Asian automotive, press, and machine tool industries. These systems were built to a standard of mechanical and electrical robustness that many current-generation platforms do not match for heavy industrial duty cycles. The CLC-D02.2 card specifically handles the position loop computation — interpolating encoder feedback, executing the positioning profile, and communicating axis status to the supervisory controller.

There is no functional equivalent card available from current Bosch Rexroth product lines. The architecture of the CLM/CLC platform is proprietary; the card slot, bus protocol, and firmware interface are not replicated in any modern successor product. This means that for a facility operating this equipment, the only paths when a CLC-D02.2 fails are: (1) locate a verified spare from the secondary market, or (2) undertake a full drive system replacement. Path 2 is not a maintenance decision — it is a capital project.

Facilities that have extended the service life of their Indramat-based lines by 5 to 10 years through strategic spare parts procurement consistently report the same outcome: the cost of maintaining a critical spares inventory for legacy drives is a fraction — typically 3% to 8% — of the cost of a forced platform migration. The CLC-D02.2 is precisely the type of component that belongs in that inventory. It is a single-card failure mode that can halt production for weeks if no spare is on hand, and it is a straightforward swap when one is available.

Condition & Reliability Assurance

DriveKNMS applies a 5-stage inspection protocol to all obsolete control cards before they are offered for sale. This process is not a visual check — it is a structured technical evaluation designed to identify the failure modes specific to cards of this age and design generation.

Stage 1 – Electrolytic Capacitor Assessment: Capacitors on cards of this era are the primary age-related failure point. Each capacitor is inspected for physical deformation, electrolyte leakage, and ESR deviation. Cards with capacitor degradation are either reconditioned with matched-specification replacements or removed from saleable inventory.

Stage 2 – Firmware Version Verification: The firmware revision on the card's EPROM is logged and cross-referenced against known compatible versions for the target CLM/CLC platform. Mismatched firmware versions are a common source of post-installation faults in legacy drive systems.

Stage 3 – Pin and Connector Inspection: All edge connectors and board-mounted connectors are examined under magnification for oxidation, pin deformation, and contact contamination. Corroded contacts are cleaned using appropriate contact restoration procedures.

Stage 4 – PCB Integrity Check: Board traces, solder joints, and component mounting are inspected for cold joints, micro-fractures, and any evidence of prior repair work. Prior repairs are disclosed.

Stage 5 – Functional Verification: Where test equipment is available for the specific platform, cards undergo powered functional testing. Test results are documented and available upon request.

Key Features for System Maintenance

The CLC-D02.2 is a direct hardware replacement for the original card position in the CLM/CLC controller chassis. Installation does not require reprogramming of the supervisory PLC, reconfiguration of the drive parameters stored in the controller, or any mechanical modification to the machine. The card seats into the existing slot, the controller recognizes it on power-up, and the axis resumes operation under the existing program.

This drop-in replacement characteristic is the core economic argument for sourcing a spare rather than migrating the platform. Engineering hours for a card swap are measured in hours. Engineering hours for a drive platform migration on a multi-axis machine are measured in weeks. The CLC-D02.2 spare eliminates the migration trigger entirely — the machine continues to run on its existing program, with its existing mechanical calibration, without any revalidation burden on the production team.

For facilities operating under ISO or automotive quality management systems, avoiding a drive platform change also avoids the revalidation and re-qualification process that a new drive system would require. This is a compliance cost that is rarely included in migration cost estimates, and it is not trivial.

FAQ

Q: What warranty applies to an obsolete card like the CLC-D02.2?
A: DriveKNMS provides a 90-day warranty covering functional performance under normal operating conditions. Given the age of this product line, warranty terms are confirmed in writing at the time of sale. Extended warranty arrangements are available for volume purchases — contact us to discuss.

Q: How do I know the card is genuine and not a counterfeit or substandard repair?
A: All cards are sourced from decommissioned OEM equipment or verified industrial surplus channels. The card's hardware revision, date codes, and component markings are inspected for authenticity. Any prior repair work identified during inspection is disclosed in the product condition report provided with the shipment.

Q: Should we hold more than one CLC-D02.2 in our spares inventory?
A: For any facility with more than two axes running on CLM/CLC controllers, holding a minimum of two CLC-D02.2 cards is a defensible maintenance position. The global supply of this card is finite and decreasing. Lead times from the secondary market will lengthen as remaining stock is absorbed. Procurement decisions made under emergency conditions — after a failure has already occurred — consistently result in higher prices and longer downtime. Planned procurement at current availability is the lower-cost path.

Q: Can you source other Indramat CLC/CLM series components?
