Siemens MICROMASTER · AC-VSD (Variable Speed Drive)

Siemens 6SE9212-1BA40

The 6SE9212-1BA40 is no longer supplied by Siemens. If one fails, the program is what gets you running again.

  1. Active RolloutSold and supported normally
  2. Phase OutRetirement announced, still orderable
  3. CancellationNormal sale ended, spares may remain
  4. Total DiscontinuationNo manufacturer supply or repair

ECS stage: Total Discontinuation.

Is the Siemens 6SE9212-1BA40 discontinued?

On ECS's lifecycle assessment, the 6SE9212-1BA40 is discontinued and no longer supplied by Siemens.

Source: ECS lifecycle assessment, based on ECS's internal lifecycle data in Command Centre. Last checked . Always confirm a specific part's status with the manufacturer before buying or planning a migration.

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.

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 6SE9212-1BA40

Is the Siemens 6SE9212-1BA40 discontinued?

On ECS's lifecycle assessment, the 6SE9212-1BA40 is discontinued and no longer supplied by Siemens.

Can I still buy a 6SE9212-1BA40?

Not from Siemens. Surplus and refurbished sellers may have stock; check provenance and test before fitting.

How do I back up a 6SE9212-1BA40?

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 6SE9212-1BA40 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
