Product Overview
The B&R 8BVI0028HWD0.000-1 is a high-performance two-axis inverter module within B&R Industrial Automation’s (B&R / 贝加莱) ACOPOSmulti modular drive system, purpose-engineered as the power stage that converts DC bus energy into precisely controlled three-phase AC for servo motors in demanding multi-axis machine automation. As a wall-mounting dual inverter, the B&R 8BVI0028HWD0.000-1 integrates two fully independent power inverters within a single compact 53mm-wide module, each axis rated at 3.8A continuous current, making it the ideal “power brick” for building dense, scalable servo architectures in packaging lines, printing presses, textile machines, plastic injection molding cells, and robotic workcells. The B&R 8BVI0028HWD0.000-1 draws its DC bus and 24V auxiliary power from the ACOPOSmulti base unit, sharing common power supply, braking resistor, and real-time POWERLINK communication infrastructure with other inverter modules in the same drive rack—dramatically reducing wiring, cabinet footprint, and total installed cost compared to discrete single-axis drives.What truly distinguishes the B&R 8BVI0028HWD0.000-1 is its comprehensive safety and integration feature set. The module incorporates integrated uncontrolled standstill and safe stop (STO) functionality, an integrated connection for motor holding brake and temperature sensor, and two dedicated slots for ACOPOSmulti plug-in modules—enabling flexible expansion of encoder interfaces, safety functions, or communication protocols without changing the base inverter hardware. With a nominal operating temperature range of 5 to 40°C (extendable to 55°C with derating), IP20 protection per EN 60529, pollution degree 2 per EN 61800-5-1, and overvoltage category III, the B&R 8BVI0028HWD0.000-1 is built to thrive in industrial control cabinet environments worldwide. Its 8.8W nominal standby loss, IE2 energy efficiency classification, and 0.2µF discharge capacitance reflect B&R’s meticulous attention to both performance and power-quality compliance, while CE and UK CA certifications underscore its global market readiness.

Main Features and Advantages
The B&R 8BVI0028HWD0.000-1 delivers exceptional power density through its dual-axis architecture. By integrating two fully independent 3.8A power inverters into a single 53mm-wide module, the B&R 8BVI0028HWD0.000-1 effectively doubles the servo axis count per cabinet linear centimeter compared to single-axis modules, enabling machine builders to pack 4, 8, 16, or more axes into remarkably compact enclosures. This “power stage on a narrow pitch” philosophy dramatically reduces control cabinet volume, cooling requirements, and wiring labor—translating directly into lower capital expenditure and higher machine competitiveness.Integrated safety is a defining strength of the B&R 8BVI0028HWD0.000-1. The module’s built-in uncontrolled standstill (STO) and safe stop functionality comply with modern machinery safety directives without requiring external safety relays or separate safety-rated drive modules. The two electrically isolated trigger inputs on the B&R 8BVI0028HWD0.000-1 accept 24VDC safety signals with industry-leading 52µs response time (rising edge) and ±0.5µs precision thanks to digital filtering, ensuring rapid, deterministic reaction to emergency stop or safety light curtain events. This tight integration of safety into the power stage itself simplifies machine certification and reduces component count.Unmatched expansion flexibility sets the B&R 8BVI0028HWD0.000-1 apart from conventional drives. With two dedicated plug-in module slots, the B&R 8BVI0028HWD0.000-1 can be customized on-site with ACOPOSmulti plug-in modules for encoder interfaces (EnDat, SSI, BiSS, Sin/Cos, TTL), SafeMOTION safety functionality, or communication protocol adaptation. This modular approach means the same base inverter hardware can serve wildly different applications—from simple printing press tension control to complex robotic path following—simply by swapping plug-in modules. The integrated motor holding brake connection and dual temperature sensor ports (500Ω to 5kΩ range) further eliminate external conditioning hardware, allowing the B&R 8BVI0028HWD0.000-1 to directly interface with motor brake coils and PTC/KTY temperature sensors.Energy efficiency and power quality are engineered into the B&R 8BVI0028HWD0.000-1 at the circuit level. The module’s IE2 efficiency classification (3.3% to 4% power dissipation relative to continuous apparent power across load conditions) reflects optimized IGBT switching and low-loss DC bus design, reducing both energy consumption and heat generation within the cabinet. The 8.8W nominal standby loss and 0.2µF discharge capacitance ensure compliance with stringent power quality standards while minimizing idle power draw. Galvanic isolation between trigger inputs and the inverter module, plus isolation between input channels themselves, protects the B&R 8BVI0028HWD0.000-1 from field-side electrical faults and eliminates ground loop interference—critical for reliable operation in electrically noisy industrial environments.
