Bottom line
What this comparison can establish
A matching DDS basic unit is not automatically a matching configured drive. Preserve the module stack, firmware and parameter context.

How to Identify a Configured DDS Drive
A DDS request often begins with the basic-unit label, but the operating drive can include command and plug-in modules, a software module, firmware and machine parameters. Those items must be recorded in position before hardware is separated.
Side-by-side identity
What each product label must tell you
DDS02
Browse products →- Role
- DDS basic-unit family represented by multiple cooling, current and feedback designs.
- Verify
- Basic-unit code plus command module, plug-ins, software module, firmware and motor.
- Do not assume
- Do not remove modules before recording slot order and labels.
DDS03
Browse products →- Role
- Later DDS basic-unit group requiring the same configured-assembly discipline.
- Verify
- Complete base-unit and installed-module identity, firmware, parameters, supply and motor.
- Do not assume
- A DDS03 base unit alone does not describe the machine-ready configuration.
Decision path
Turn the cabinet into a useful evidence set
What is the basic unit?
Capture: Photograph the complete DDS02 or DDS03 basic-unit label.
Then: Verify design, cooling, current and feedback fields.
What is installed in each slot?
Capture: Photograph every module and software label before removal.
Then: Build a slot-by-slot configuration record.
What machine data exists?
Capture: Locate firmware records, parameters, backups and the connected motor.
Then: Define the preservation and startup plan before exchange.
Official manufacturer records
Use the edition that matches the installed hardware.
Verified downloads open on the manufacturer’s site. Other references open a library entry with assistance options. Confirm the applicable edition, physical nameplate and machine documentation.
Common questions
Before you request a configured match
Is the DDS basic-unit number enough to order a replacement?
Usually not. The operating configuration can depend on command, plug-in and software modules, firmware, parameters, motor and supply.
Should modules be shipped with the base unit?
Document the complete installed assembly first, then confirm the requested evaluation or exchange scope before shipping anything.
Why preserve the slot order?
Slot position is part of the evidence needed to reconstruct and compare the configured drive.
