Bosch Rexroth HCD90 271-5818 – Drive Control Motherboard | NSLN100 / NLON100 Platform
The Bosch Rexroth HCD90 271-5818 is the core control motherboard for the NSLN100 / NLON100 series AC servo drive units within the Rexroth HCD90 drive platform. Designed for high-precision motion control in demanding industrial environments, this board governs all primary drive logic, feedback processing, and communication interfacing. Procurement engineers sourcing replacement or spare boards for Rexroth HCD90-series installations will find this unit fully interchangeable with OEM specifications.
Product Positioning: This motherboard is a direct OEM-equivalent replacement component for Bosch Rexroth HCD90 series servo drives. It is suited for MRO (Maintenance, Repair & Overhaul) procurement, spare-parts inventory management, and system upgrade projects across automotive, machine tool, packaging, and press automation sectors.

Engineering Advantages
- OEM-Equivalent Design: Manufactured to Bosch Rexroth original specifications — no firmware or parameter re-mapping required on installation.
- Plug-and-Play Replacement: Direct board-swap compatibility with NSLN100 and NLON100 drive chassis; no mechanical modification needed.
- Integrated Feedback Processing: Onboard resolver/encoder interface circuitry supports high-resolution position feedback without external signal conditioning.
- Robust EMC Design: Shielded PCB layout and filtered I/O conform to CE/EMC directives for industrial drive environments.
- Tested Before Shipment: Each unit undergoes functional power-on and signal-path verification prior to dispatch.
System Architecture & Signal Flow
The HCD90 271-5818 motherboard sits at the center of the HCD90 drive’s control hierarchy. It receives setpoint commands via the fieldbus interface (SERCOS / Profibus / analog, depending on drive configuration), processes position and velocity feedback from the motor encoder or resolver, executes the current-control loop in real time, and outputs PWM gate signals to the power stage IGBT module. Fault detection, parameter storage (EEPROM), and diagnostic LED status reporting are all managed on this board.
Signal flow: Fieldbus Input → Setpoint Decoder → Position/Velocity Controller → Current Controller → PWM Output → Power Stage

Technical FAQ
Q: Is the 271-5818 board compatible with both NSLN100 and NLON100 drive variants?
A: Yes. The 271-5818 motherboard is the common control board used across both NSLN100 and NLON100 chassis variants in the HCD90 series.
Q: Do I need to re-parameterize the drive after replacing this board?
A: Parameter data is stored in the drive’s EEPROM on this board. If replacing a failed board, you will need to reload your axis parameters via the Rexroth IndraWorks commissioning tool or from a backup parameter file. Konmask can assist with parameter recovery guidance.
Q: What is the lead time for this part?
A: In-stock units ship within 3–7 business days. For out-of-stock situations, typical lead time is 4–8 weeks. Contact us for real-time availability.
Q: Can Konmask provide a test report or certificate of conformity?
A: Yes. Functional test reports and certificates of conformity are available upon request for quality-assurance documentation requirements.
Q: What export documentation is provided?
A: Standard export package includes commercial invoice, packing list, and certificate of origin. ECCN classification and AES filing available for US-bound shipments.
