Rexroth Indramat CDB02.1B-ET-EC-EC-NN-NN-NN-NN-NN-FW Dual-Axis Drive

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The Bosch Rexroth CDB02.1B-ET-EC-EC-NN-NN-NN-NN-NN-FW is a dual-axis digital control section designed for the compact IndraDrive family. Operating as the brain of a double-axis drive platform, this unit independently manages motion loops, encoder feedback interpretation, and network communication for two servo axes simultaneously. The ET option delivers flexible Multi-Ethernet connectivity, allowing real-time synchronization over PROFINET, EtherNet/IP, EtherCAT, or Sercos III protocols without requiring hardware changes. Dual EC encoder slots enable high-precision position evaluation for both axes across standard feedback types.

Procuring this control section as New Surplus inventory provides immediate machine recovery and avoids multi-week OEM manufacturing delays. This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned line, and not refurbished. All modules undergo quality verification to ensure original manufacturer reliability. Avoiding second-hand units eliminates the risks of corrupted flash memory, worn connector contacts, and latent circuit degradation. Maintaining a verified New Surplus CDB02.1B control section on-site guarantees fast swap-outs during drive hardware faults, keeping multi-axis CNC machines, packaging lines, and robotics cells operational.

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

1. Turn off main incoming power and execute Lock-Out/Tag-Out (LOTO) on the drive enclosure. Wait at least 5 minutes for internal DC bus capacitors to discharge fully before touching terminals.
2. Put on an anti-static wrist strap connected to a verified earth ground point to protect sensitive microprocessors from Electrostatic Discharge (ESD).
3. Verify that the correct firmware micro-SD card (FW) matching your machine parameters is prepared and clean.

Stage 2: Removal

1. Unplug all field communication cables (RJ45 Multi-Ethernet ports) and encoder feedback connectors from Axis 1 and Axis 2.
2. Unfasten top/bottom retaining screws securing the CDB02.1B control section to the power section housing.
3. Gently pull the control section straight out from the power module slot, taking care not to bend backplane connector pins.

Stage 3: Installation (Clone & Seat)

1. Remove the replacement New Surplus CDB02.1B module from its anti-static packaging.
2. Insert the system firmware micro-SD card into the designated firmware card slot on the control section.
3. Align the CDB02.1B card with the guide tracks of the power module, slide it in firmly until backplane contacts engage, and tighten the retaining screws.

Stage 4: Power-On & Testing

1. Reconnect Multi-Ethernet cables, feedback cables, and I/O harnesses to Axis 1 and Axis 2 ports.
2. Restore 24 VDC control power. Observe the onboard LED/display screen during startup self-test.
3. Use Rexroth IndraWorks software to verify parameter loading, confirm Multi-Ethernet network synchronization (e.g., EtherCAT/PROFINET status green), and clear drive enable interlocks before running motor motion tests.

Firmware/Software Versions & Upgrade Notes

• Firmware Designator (FW): The “-FW” suffix indicates that firmware must be flashed or loaded via a micro-SD parameter memory card. The physical control section hardware is universal; drive performance and communication protocols are configured by the loaded firmware version (e.g., FWA-INDRV*-MPH/MPB).
• Multi-Ethernet Flexibility (ET): The Multi-Ethernet hardware interface supports multiple protocols. Protocol selection (Sercos III, PROFINET IO, EtherNet/IP, or EtherCAT) is made via firmware configuration settings in IndraWorks.
• Encoder Interface (EC/EC): Both Axis 1 and Axis 2 slots are factory-fitted with EC standard encoder hardware, supporting EnDat 2.1/2.2, Hiperface, 1Vpp, and TTL encoders.
• Unpopulated Slots (NN): Options 4 through 8 are unpopulated (NN), leaving the base board streamlined for cost-effective dual-axis execution without unnecessary auxiliary cards.

Frequently Asked Questions (FAQ)

Q: This unit is listed as New Surplus. How can I be sure it is not pre-owned or rebuilt?

A: This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo quality verification to ensure OEM-level reliability. Our stock originates from canceled OEM machine projects, system integration inventory overstock, and spare holds. Every unit features pristine backplane contacts, factory serial labels, and zero field operation hours.

Q: How does your pricing compare to buying factory-direct from Bosch Rexroth or an online broker?

A: Our pricing reflects the cost of securing genuine New Surplus inventory globally. It may be slightly higher than a risky refurbished unit, but it is substantially less than OEM list prices, and it buys you 100% peace of mind. You bypass extended manufacturing lead times while avoiding corrupted memory chips and worn connector pins common in second-hand modules.

Q: Does this control section come pre-loaded with drive firmware?

A: The “FW” designation means the hardware requires a system firmware card (FWA/FW) containing machine parameters and operational software. You can transfer your existing firmware micro-SD card from your original .1B board directly into this replacement unit to retain parameter settings.

Q: What is the difference between .1B and CSB02.1B control sections?

A: The is a double-axis control section capable of controlling two separate motors/axes from a single board. The CSB02.1B is a single-axis control section designed for single-motor applications.

Q: What warranty and quality verification process do you provide with this drive controller?

A: We supply a full 1-Year functional replacement warranty with every .1B control section. Before dispatch, each unit undergoes physical inspection, pin/slot continuity checks, and anti-static packaging controls to guarantee immediate field deployment readiness.
