Product Introduction

The Bosch Rexroth DKC02.3-100-7-FW installs vertically inside a servo control cabinet as part of a multi-axis motion system. The rear heatsink, ventilation channels, and terminal arrangement require proper cabinet planning because this drive dissipates significant heat during continuous operation (especially during high acceleration and braking cycles). Keep airflow paths clear. Inspect the power terminals and DC bus connections before energization.

This EcoDrive controller provides three-phase motor output control with a 100 A rated current and a 700 V DC bus nominal voltage. It interfaces with motion controllers through the designated communication option and is commonly used with Rexroth Indramat servo motors in automated machinery. Firmware is a separate consideration during replacement. Verify the installed drive parameters, controller revision, and motor data before returning equipment to service.

Global Compliance & Industry Certifications

Expected compliance considerations for the Bosch Rexroth .3-100-7-FW include:

• CE Mark — applicable for European industrial machinery installations when installed according to EMC and safety requirements.
• UL/cUL Recognition — may apply depending on the certified drive system configuration.
• RoHS Compliance — dependent on production revision and documentation.
• IEC 61800 Drive System Standards — relevant for adjustable speed electrical power drive systems.
• ATEX/IECEx — not a standalone certification for this servo drive; hazardous-area operation requires a complete certified system design.
• Marine approvals (DNV GL) — only applicable for specific marine automation packages.

CE and EMC compliance are important for servo drives because high-frequency switching from the power stage can affect nearby instrumentation and communication wiring if cabinet installation is incorrect.

Verify specific lot certifications with OEM.

Long-Term Storage & Asset Preservation Guide

Store the .3-100-7-FW in a dry indoor environment with the original packaging sealed. Protect the terminal covers, connector pins, and ventilation openings from dust accumulation.

Maintain warehouse humidity below 60% RH. Long storage periods can affect internal electrolytic capacitors, insulation materials, and connector surfaces.

Before installation after extended storage:

• Inspect the DC bus capacitor condition.
• Check connector oxidation.
• Verify cooling fan movement.
• Confirm firmware and parameter compatibility.
• Perform controlled power-up procedures according to maintenance practice.

Do not place heavy equipment on top of stored drives. The front interface and plastic covers can crack under uneven loading.

Physical Installation Prerequisites

• Install vertically inside a suitable electrical cabinet.
• Mount on a rigid metal back panel capable of supporting approximately 10 kg.
• Provide sufficient airflow around the heatsink area.
• Leave at least 150 mm clearance above and 80 mm below the drive for cooling airflow.
• Connect protective earth before applying power.
• Use correctly rated AC input and motor cables.
• Separate encoder wiring from high-current motor cables.
• Verify DC bus connections before commissioning.
• Check cabinet temperature under full machine load.

Buyer’s FAQ (Logistics & Compliance Focus)

Q: What HS Tariff Code is commonly used for the Rexroth .3-100-7-FW?

A: Servo drive controllers are commonly classified under HS 8504.40 for static converters, although customs classification can vary depending on the declared function and importing country requirements.

Q: Does Country of Origin (COO) affect importing this Rexroth servo drive?

A: Yes. COO affects customs clearance, duty calculations, warranty traceability, and industrial asset records. Match the COO information across the invoice, packing list, and product label.

Q: Should shipping insurance be arranged for this drive controller?

A: Recommended. The unit contains power semiconductors, capacitors, control electronics, and precision connectors. Shock or moisture exposure may cause failures that appear only during startup.

Q: Does the .3-100-7-FW include the latest firmware pre-loaded?

A: Firmware availability depends on the specific hardware revision and supplied configuration. Some references indicate firmware is handled separately from the drive
