Selection Guide
Use the table below to identify the correct DKC model for your application:
- DKC04.3-040-7-FW — 40 A | Light-duty single-axis
- DKC04.3-100-7-FW — 100 A | Mid-range CNC or packaging axis
- DKC04.3-200-7-FW — 200 A | Heavy-duty high-torque axis ✓ This model
- DKC11.3-200-7-FW — 200 A | ECODRIVE 03 platform (newer firmware ecosystem)
Key selection parameters: peak current requirement → bus protocol → motor encoder type → cabinet depth. Contact our engineers if you need a custom selection recommendation.

Replacement & Compatibility FAQ
Q: Can the DKC04.3-200-7-FW replace a DKC11.3-200-7-FW directly?
A: Mechanically and electrically similar, but firmware and parameter sets differ. A parameter migration step is required. Konmask can provide migration support.
Q: Is the FW firmware version field-upgradeable?
A: Yes, via Rexroth IndraWorks or DriveTop software using the official Rexroth firmware update procedure.
Q: What is the difference between DKC04.3 and DKC11.3?
A: DKC04.3 belongs to the ECODRIVE Cs platform; DKC11.3 belongs to ECODRIVE 03. Both share similar hardware but use different firmware ecosystems and parameter structures.
Q: Do you supply refurbished units?
A: We supply both new and professionally refurbished units. All refurbished units pass full functional testing and carry a 90-day warranty.
