Bosch Rexroth Indramat DKC02.3-100-7-FW | 100A SERCOS EcoDrive03 Controller

Description

1. Product Overview

The Bosch Rexroth Indramat DKC02.3-100-7-FW is a high-power, dynamic digital drive controller belonging to the iconic EcoDrive03 platform. It acts as the precision engine behind advanced AC brushless servo motor setups, making it a cornerstone for multi-axis coordinated motion control.

The configuration code 02 signifies that this drive relies on the SERCOS interface standard—a real-time, noise-immune serial communication loop executed over fiber optic cables. With its heavy-duty 100 A current rating and 700 V DC bus architecture, the DKC02.3 provides instantaneous torque responses and smooth velocity profiles, especially when executing demanding acceleration cycles on high-inertia loads. The “FW” designation indicates it requires standard configurable firmware modules to adapt smoothly to individual motor kinematics.

Key Applications:

• Automotive Assembly: Coordinated robotic handling, stamping lines, and conveyor tracking.
• Packaging Systems: High-speed continuous wrapping, cartoning, and multi-axis sealing bars.
• Printing & Paper Processing: Precise tension and registry control across multiple synchronized rollers.
• Material Handling: Automated storage and retrieval systems (ASRS) requiring rapid position settling.

7. FAQ

Q: What is the purpose of the firmware slot on the DKC02.3?

The DKC02.3-100-7-FW is shipped with standard basic hardware structures. Its operational parameters and compatibility profiles are determined by a separate, pluggable firmware card (e.g., FWA-ECODR3-SMT-…). If you are replacing an existing unit, you should remove the firmware card from your old drive and plug it into this new one to maintain existing configuration parameters.

Q: Can this drive be used to replace a lower current model like the 40A version?

Yes, physically and electronically it will work since it handles up to 100A, but you must scale your parameters and motor limits down to match the continuous thermal ratings of your current motor. Conversely, a 40A drive cannot replace a 100A drive.

Q: How does the SERCOS fiber-optic loop connection handle a single unit failure?

Since SERCOS is a ring architecture, a fatal fault on one drive’s processor can break the ring loop communication for the remaining axes. It is critical to use healthy fiber optic jumpers (e.g., IKO0982) and ensure that the drive passes its basic self-diagnostic loop initialization before starting production.
