Bosch Rexroth Indramat DKC02.3-040-7-FW – ECODRIVE 03 Servo Drive Controller for 40 A Applications

This unit is part of the well-proven ECODRIVE 03 family. The DKC02.3-040-7-FW is a compact servo drive controller typically used with Rexroth MKD/MHD/MDD synchronous servo motors in packaging, printing, and general automation lines. One thing I appreciate is how straightforward it is to swap into existing panels—wiring, parameter handling, and firmware are all designed to be service-friendly, which in many cases cuts downtime to a minimum.

Order Placement Process and Guarantees

• Warranty: 365 days
• Lead time: 1 week when in stock; no more than 1 month at the latest
• Payment terms: 50% advance payment; full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• 40 A power stage – Sized for mid-to-high torque servo axes; ideal for heavier feeders, winders, or high-inertia loads.
• ECODRIVE 03 platform – Stable, widely deployed generation with strong parts availability and predictable lifecycle support.
• Modular firmware (-FW) – Firmware supplied separately; you can match the firmware level to your installed base for consistent behavior.
• Flexible control modes – Position, velocity, and torque control for synchronous servo motors; resolver feedback supported in typical setups.
• Fieldbus options – Common interfaces (e.g., SERCOS, PROFIBUS, INTERBUS) available depending on option cards; helpful when retrofitting mixed fleets.
• Robust protection – Overcurrent, overtemperature, and DC bus monitoring functions help safeguard both drive and motor.
• Booksize, panel-mount design – Fits cleanly in standard control cabinets with top/bottom ventilation space.
• Service-friendly – Parameter backup/restore and clear diagnostics reduce commissioning time; from my experience, that’s a big win for maintenance teams.

Technical Specifications

Application Fields

You’ll commonly see the DKC02.3-040-7-FW driving axes in packaging form-fill-seal machines, folder-gluers, labelers, and cartoners. It also performs well in printing lines (web tension, register control), woodworking equipment (feed and positioning axes), and general material handling. A maintenance manager told me they favor this model for retrofit projects because it “just behaves the same as the rest of our ECODRIVE rack—no surprises in tuning.”

Advantages & Value

• Drop-in compatibility – Seamless with existing ECODRIVE 03 environments; typically no cabinet redesign.
• Stable lifecycle – Parts and documentation are widely available, which seems to shorten mean time to repair.
• Cost control – Predictable commissioning and minimal engineering overhead save both time and budget.
• Supportable firmware – Separately supplied firmware lets you align versions across multiple lines to keep behavior consistent.

Installation & Maintenance

• Cabinet & ventilation – Mount vertically in a closed control cabinet to EN/IEC standards; allow unobstructed airflow above/below the heat sink.
• Wiring – Use correctly rated line protection, line reactor/filter as required, and shielded motor/feedback cables with proper grounding on the drive side.
• Braking – Size the external brake resistor for your deceleration profile; check duty cycle and ambient temperature.
• Safety – Lock out/tag out before servicing; discharge the DC bus fully; verify earthing; observe creepage/clearance.
• Commissioning – Load matching firmware, restore parameters, and run autotune. From my experience, backing up parameter sets before changes saves a lot of time.
• Routine care – Quarterly dust cleaning, connector inspection, fan check, and periodic firmware/parameter audits. Keep cabinet temperature stable to extend component life.

Quality & Certifications

• Conformity: CE; UL recognition and RoHS compliance in many cases for ECODRIVE 03 family units
• Manufacturer’s policy: standard warranty coverage typically applies when installed and operated per Rexroth guidelines
• Warranty provided here: 365 days
