The SIEMENS 6SE7028‑0ES87‑2DA1 is a braking module designed for use with SINAMICS and SIMOVERT MASTERDRIVES drive systems. It’s a spare part used to
provide controlled deceleration and energy dissipation in electromechanical drive applications, such as conveyor
systems, lifts, cranes, and other motor‑driven machinery.
Frequently Asked Questions About 6SE7028-0ES87-2DA1
|
1. What does this braking module actually do? It provides dynamic braking for DC link circuits in SINAMICS/SIMOVERT drives, absorbing and dissipating energy produced during motor deceleration, which helps safely slow down the system and protect electronics from overvoltage. 2. What voltage and power levels does it support? The module is specified for 510–650 V DC and up to 50 kW braking power, making it suitable for mid‑range industrial drives. 3. Is the 6SE7028‑0ES87‑2DA1 still manufactured or supported by Siemens? No — it’s listed as a discontinued (phase‑out) part, meaning SIEMENS has stopped production and support. It may still be available as new old‑stock or refurbished units from third‑party sellers. |
