Use this guide before removing an ECODRIVE controller, moving firmware or parameters, or comparing a candidate unit from inventory.
ECODRIVE comparison / DKC controllers
DKC01 vs DKC02 vs DKC03 Interface Checklist
DKC01, DKC02 and DKC03 identify command-interface families within documented ECODRIVE generations; they do not simply identify output size. A safe review starts with the entire type code, especially the design number after the decimal.
Separate family from design generation
- Record DKC01, DKC02 or DKC03 together with the design number after the decimal.
- Do not apply a .3-generation interface description to a .1-generation controller.
- Use the exact factory manual for the installed design and firmware release.
Common ECODRIVE03 interface context
- DKC01.3 is commonly documented with analog and parallel command architecture.
- DKC02.3 is commonly documented with SERCOS interface architecture.
- DKC03.3 is commonly documented with PROFIBUS-DP architecture.
Verify beyond the interface
- Current and voltage fields from the complete controller code.
- Connected motor, encoder support, feedback cabling and supply architecture.
- Firmware family, release, parameter handling and any installed option hardware.
Do not assume
- Do not compare only the 01, 02 or 03 family number.
- Do not move removable firmware or memory hardware without recording labels and position.
- Do not promise a fieldbus match without checking the physical connectors and full code.
Common questions
What this checklist can and cannot establish.
Does DKC01 mean a smaller controller than DKC03?
No. The family number identifies interface architecture within a documented generation; current and voltage are separate fields.
Why is the number after the decimal important?
It identifies a hardware design generation. Interface and planning details from one generation should not be applied automatically to another.
What should I photograph before removal?
Capture the full label, firmware, connectors, removable modules, connected motor and cabinet supply arrangement.
