Configuration preservation / drives and controls
Preserving Firmware, Parameters & Modules
Legacy motion hardware may carry machine-specific behavior in removable software modules, firmware labels, option cards, storage media or parameter sets. A hardware match can still fail operationally when the configuration record is incomplete.
Build a configuration record
- Photograph every module and slot in place, then photograph each label close enough to read.
- Record firmware family, release, function ID/version, communication and feedback options.
- Record removable storage, software modules, programming modules and control sections as separate items.
Protect machine-specific information
- Use the machine builder's documented backup and restore procedure when available.
- Keep original hardware, photos and exported records together under one machine and axis reference.
- Do not erase, update or initialize a candidate unit before the preservation plan is confirmed.
Request the right review
- Identify whether the need is a like-for-like hardware repair, a configured exchange or a broader retrofit.
- Include the machine state, available backups and whether the original unit still communicates.
- Ask specifically how firmware, parameters and option hardware will be handled.
Do not assume
- Do not assume firmware is included because a controller has FW in the type code.
- Do not move an option card without recording its slot and surrounding modules.
- Do not rely on one screenshot as the only parameter backup.
Common questions
What this checklist can and cannot establish.
Why is a hardware match not always enough?
Firmware, parameters, option modules, communication and machine-specific application data can determine whether the installed system operates correctly.
What should I record first?
Capture the complete unit, all module labels and slot positions, firmware labels, removable media and the connected machine context.
Can Litco identify a unit without a backup?
An identification or repair request can still begin, but the missing backup should be stated clearly so configuration risk can be reviewed.
