Technical Principles and Innovative Values
- Innovation Point 1: Two Independent Inverters in 53 mm Width. The 8BVI0028HWD0.000-1 packs two galvanically separated power stages into a single compact module. Each axis can drive a different motor type, run independent control loops, and be serviced individually—effectively doubling rack density compared to single-axis designs without compromising electrical isolation.
- Innovation Point 2: Shared DC Bus Energy Recovery. As part of the ACOPOSmulti architecture, the 8BVI0028HWD0.000-1 draws from a common DC link. When one axis decelerates, the regenerated energy flows back to the bus and is instantly consumed by another axis that is accelerating. This dramatically reduces dependence on external brake resistors and cuts total energy consumption in cyclic motion applications.
- Innovation Point 3: Integrated Safety from the Ground Up. The 8BVI0028HWD0.000-1 embeds uncontrolled standstill and safe stop functions directly in the power stage. Combined with B&R SafeMOTION technology, it supports STO, SS1, SS2, SOS, SLS, and SBC functions up to SIL 3 / PLe, eliminating the need for external safety relays and simplifying compliance with machinery directives.
- Innovation Point 4: Sub-Microsecond Synchronization via POWERLINK. Communicating over the ACOPOSmulti backplane bus with POWERLINK real-time Ethernet, the 8BVI0028HWD0.000-1 executes technology functions—electronic gearing, camming, flying shear, CNC interpolation—with switching times under 400 µs. Motion commands are processed directly on the drive, making reaction speed immune to higher-level network load.
- Innovation Point 5: Extensible via Two Plug-in Slots. Each 8BVI0028HWD0.000-1 provides two slots for ACOPOSmulti plug-in modules, enabling onboard encoder interfaces (EnDat 2.1/2.2, SSI, BiSS, Sin/Cos, TTL), resolver evaluation, or encoder buffering with battery backup. This keeps feedback wiring extremely short, minimizing noise susceptibility and improving position accuracy.
- Innovation Point 6: Rugged, Service-Friendly Design. With IP20 protection, 2.5 kV-class isolation, and a wall-mountable form factor, the 8BVI0028HWD0.000-1 thrives in harsh industrial cabinets. The module can be slipped out and replaced without dismantling motor or DC bus wiring, achieving the shortest possible mean time to repair.
