What Total Discontinuation means for you
The manufacturer has finished with the part. You may still find one through surplus or refurbished sellers, or in another site's stores, but that is not a supply chain. When a unit fails, your options are to find one and restore the program onto it, or to migrate the machine.
Both routes start in the same place: having the program. Without a backup, a found spare is just hardware.
How ECS defines Total Discontinuation · all four lifecycle stages
Before replacing a variable speed drive
Matching the motor power and supply voltage is only the start with a drive replacement. We would capture the full parameter set, motor nameplate data, acceleration and deceleration behaviour, control terminals, braking arrangement and any network communications.
Even a manufacturer-recommended successor can use different parameter numbering or I/O behaviour. A verified parameter backup taken while the drive is healthy is normally far easier to work from than reconstructing the machine setup after a failure.

Common questions about the ATV31HU75N4
Is the Schneider Electric ATV31HU75N4 discontinued?
Yes. The ATV31HU75N4 is discontinued (since December 2011, support until December 2015) and no longer supplied by Schneider Electric. Its successor is the ATV320U75N4B.
What replaced the ATV31HU75N4?
Schneider Electric lists the ATV320U75N4B as the successor. Check compatibility with your machine before planning the change.
Can I still buy a ATV31HU75N4?
Not from Schneider Electric. Surplus and refurbished sellers may have stock; check provenance and test before fitting. The ATV320U75N4B is the supported route.
How do I back up a ATV31HU75N4?
It is programmed with SoMove. The exact software version and cable depend on the unit's firmware. ECS records both for every unit it captures, alongside a verified backup.
With a backup, a failed unit is hours. Without one, it is days.
A Capture audit finds every ATV31HU75N4 on your site, takes a backup of each one it can reach, and records the software version and cable needed to restore it. When a discontinued unit fails and a replacement turns up, the program is ready to load.
- Every device located, photographed and lifecycle-checked
- Backups taken on the day, with software version and cable recorded
- Findings report, plus a populated Command Centre
- No production downtime
