Use this guide before a DDS unit is removed, before modules are transferred, or when a candidate replacement has a different visible module set.
DIAX03 checklist / DDS02 and DDS03
DDS02 Configured Replacement Checklist
A DDS controller is a configured assembly. The basic unit, command and plug-in modules, software module, firmware and drive parameters work together. Replacing only the base unit code can leave critical configuration questions unanswered.
Inventory the complete assembly
- Basic unit: complete DDS type code, design generation, cooling, current and feedback fields.
- Command and plug-in modules: complete label, slot position and connector orientation.
- Software module: complete label, firmware, function identification and parameter context.
- Connected system: motor, power supply, adjacent drives and machine axis.
Photograph before disassembly
- Cabinet-wide view with the DDS position and connected power architecture visible.
- Front label, status display and every installed module label.
- Software module, connector arrangement and cable labels before disconnection.
Plan the replacement path
- Confirm whether modules and the software module will be reused, evaluated or replaced.
- Confirm motor feedback, command interface and supply-system compatibility.
- Create a documented plan for firmware, parameters and machine startup.
Do not assume
- Do not describe a bare DDS basic unit as a complete configured replacement.
- Do not change module order without a complete photo and configuration record.
- Do not assume matching current class resolves feedback, cooling or firmware questions.
Common questions
What this checklist can and cannot establish.
Is a DDS basic unit a complete replacement?
Not by itself. The installed modules, software module, firmware, parameters, feedback and cooling configuration also require review.
Should I move the software module?
Only under a documented plan. First record its complete label, firmware and relationship to the machine parameters.
What if the candidate has different modules?
Photograph both configurations and request a slot-by-slot review before transferring or powering the hardware.
