Product Introduction

The CDB02.1B control unit mounts into the Rexroth IndraDrive cabinet architecture as the command and feedback processing section for servo applications. It works together with a compatible power section, receiving motion commands through MultiEthernet communication and managing encoder feedback from connected motors (which is critical for synchronized multi-axis machinery).

This control unit is a precision electronic asset, not a field device designed for uncontrolled environments. Inspect the connector surfaces, housing, firmware identification, and interface configuration before replacement. Check the hardware revision. A visually identical spare may not contain the same interface population or firmware compatibility required by the installed drive system.

Global Compliance & Industry Certifications

Expected regulatory approvals and compliance considerations for the Rexroth CDB02.1B control unit include:

• CE Mark — applicable for EMC and low-voltage compliance when installed within an approved IndraDrive system.
• UL/cUL Recognition — may apply for industrial drive assemblies installed according to approved configurations.
• RoHS Compliance — applicable to corresponding manufacturing revisions.
• ATEX/IECEx Considerations — the control unit itself is not normally a hazardous-area certified device; classified-area installations require a complete certified system design.
• Marine Approvals (DNV GL) — require verification for specific drive system configurations.

EMC certification is especially important for servo drive electronics because high-frequency switching environments can affect encoder signals and communication stability.

Verify specific lot certifications with OEM.

Long-Term Storage & Asset Preservation Guide

• Keep the .1B inside the original anti-static ESD shielding bag. The connector pins and internal electronics are sensitive to electrostatic discharge.
• Maintain warehouse humidity below 60% RH. Moisture exposure can degrade contact surfaces and reduce insulation resistance.
• Store in a clean cabinet away from vibration, dust, and corrosive chemicals.
• Avoid repeated connector insertion cycles during storage testing. The interface contacts are designed for controlled installation, not frequent handling.
• Record firmware version, serial number, and hardware revision before placing the unit into spare inventory.

Physical Installation Prerequisites

• Install the control unit only with the compatible Rexroth IndraDrive power section.
• Ensure the cabinet provides sufficient airflow for natural convection cooling.
• Leave approximately 50 mm clearance above and below the drive assembly where cabinet design permits.
• Connect protective grounding according to site electrical requirements.
• Verify encoder cable shielding and grounding before commissioning.
• Inspect retaining mechanisms before energizing.
• Confirm MultiEthernet communication parameters match the existing motion control system.

Buyer’s FAQ (Logistics & Compliance Focus)

Q: What HS Tariff Code is commonly used for Rexroth .1B-ET-EC-EC-NN-NN-NN-NN-NN-FW?

A: Industrial servo drive control units are commonly reviewed under HS 8504 for electrical power conversion/control equipment or related automation equipment classifications. Final classification depends on customs interpretation and declared function.

Q: Does Country of Origin (COO) affect import approval for this control unit?

A: Yes. COO affects customs processing, duty evaluation, supplier qualification, and asset traceability. The COO should match the commercial invoice, packing list, and certificate of origin when required.

Q: Is shipping insurance recommended for this Rexroth control section?

A: Recommended. The unit is lightweight, but the internal electronics, connector assemblies, and firmware-dependent control hardware can be damaged by shock, moisture, or improper handling during international transport.

Q: Does the .1B include the latest firmware pre-loaded?

A: The firmware version depends on the ordered FW configuration. Confirm firmware compatibility with the installed IndraDrive system before commissioning, as firmware components may require separate ordering or validation.
