Is the Mitsubishi Electric FR-E740-300SC-EC discontinued?
On ECS's lifecycle assessment, the FR-E740-300SC-EC has been cancelled (support until March 2030): no longer sold as a current product, though spares may remain available for a period.
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 Cancellation means for you
You can no longer order it as a normal product, and nothing new should be designed around it. If machines depend on it, you want spare stock you can rely on and a migration plan. Both start with knowing how many you run and whether each has a backup.
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 FR-E740-300SC-EC
Is the Mitsubishi Electric FR-E740-300SC-EC discontinued?
On ECS's lifecycle assessment, the FR-E740-300SC-EC has been cancelled (support until March 2030): no longer sold as a current product, though spares may remain available for a period.
Can I still buy a FR-E740-300SC-EC?
Not as a normal new product. Remaining distributor stock or designated spares may still be available. Buy any you need now.
How do I back up a FR-E740-300SC-EC?
It is programmed with FR-Configurator. 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 FR-E740-300SC-EC 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
