Stöber 5000 Series Drives Are Being Phased Out – What You Need to Know
As engineers, we all know that technology moves fast. Even reliable and proven equipment eventually reaches the end of its production life-cycle. Stöber has officially announced the phase-out of their 5th generation inverter drives—the FDS 5000 frequency inverters and the SDS 5000 servo inverters.
At Classic Automation, our focus has always been on helping customers get the most out of their existing systems. With Stöber’s announcement, now is the time to plan how you’ll support your installed 5000 series equipment in the years ahead.
Key Dates for the Stöber 5000 Series Phase-Out
FDS 5000: Production will end on June 30, 2026
SDS 5000: Production will end on June 30, 2027
Once production stops, these drives will still be available—but only through Stöber’s service distribution. The FDS 5000 will be supported for four additional years (through mid-2031), while the SDS 5000 will be supported for five additional years (through mid-2032).
That may sound far away, but in automation lifecycle planning, these dates come quickly.
Why This Matters
If your plant or your customers’ facilities are still running Stöber 5000 series drives, this announcement is a clear signal to start preparing. When drives move into obsolescence, the first challenge is spare part availability. Once production stops, components become harder to source, delivery times increase, and costs often rise. Relying on factory-new replacements can quickly shift from practical to expensive.
-- Downtime risk increases over time. Waiting until parts are scarce can create costly production delays when equipment fails.
-- Spare parts availability will tighten. After official production ends, sourcing parts will become more difficult and expensive.
-- Budgets are impacted – Relying solely on last-minute replacements can quickly become expensive.
