Bottom line
What this comparison can establish
Match the complete DKC code, design generation, current and voltage fields, command interface, feedback support, firmware and connected motor. Do not substitute from the DKC prefix alone.
ECODRIVE comparison / controller identity
DKC01 vs DKC02 vs DKC03 Drive Controllers
DKC01, DKC02 and DKC03 are separate controller groups, and the design number after the decimal is also meaningful. A similar enclosure or current code does not establish that command communication, feedback, firmware or motor support is the same.
Side-by-side identity
What each product label must tell you
DKC01
Browse products →- Role
- ECODRIVE controller group documented independently from DKC02 and DKC03.
- Verify
- Complete .1 or .3 designation, current and voltage fields, interface, feedback, firmware and motor.
- Do not assume
- DKC01 and DKC11 may share documentation in some editions; that does not make every configured unit equivalent.
DKC02
Browse products →- Role
- A separate ECODRIVE controller group with its own planning records and interface context.
- Verify
- Complete design code, current class, command communication, feedback, firmware and installed-system labels.
- Do not assume
- Do not infer DKC02 compatibility from current rating or cabinet dimensions alone.
DKC03
Browse products →- Role
- A distinct ECODRIVE controller group represented across more than one documented generation.
- Verify
- Digits on both sides of the decimal, suffix, firmware, feedback, interface, motor and supply context.
- Do not assume
- DKC03.1 and ECODRIVE03 DKC03.3 material must be checked against the applicable edition.
Decision path
Turn the cabinet into a useful evidence set
Which controller group is installed?
Capture: Photograph the complete DKC01, DKC02 or DKC03 line exactly as printed.
Then: Open the matching family page and edition-specific official record.
Which hardware generation is it?
Capture: Keep the number after the decimal and all suffix fields.
Then: Reject a match that silently drops or changes the design generation.
What does the machine require?
Capture: Record motor, feedback cable, command network, firmware and supply architecture.
Then: Compare the configured system—not only the base controller.

Before you request a configured match
Can I replace a DKC01 with a DKC02 or DKC03?
A family-name comparison cannot approve that change. The exact hardware, interface, feedback, firmware, motor and machine design must be reviewed together.
Does the number after the decimal matter?
Yes. It identifies a design generation or edition context that must remain attached to the rest of the code.
Is FW a complete firmware specification?
No. FW in a designation does not by itself identify the required firmware family, release, parameters or what is included with a unit.
