Product Overview

The 8V1090.00-2​ is a high-performance single-axis servo drive engineered by B&R Industrial Automation (Austria, now part of the ABB Group) as a core component of the company’s renowned ACOPOS 1090 series. Purpose-built to deliver precise closed-loop control for brushless synchronous and asynchronous servo motors, the 8V1090.00-2​ operates from a 3-phase 400–480 VAC mains supply (±10% tolerance, 50/60 Hz) and provides 8.8 A continuous RMS output current with up to 24 A peak capability, enabling motor power up to 4 kW at 400–480 VAC. As a definitive member of B&R’s ACOPOS family—a product line that has established the global benchmark for high-dynamic industrial motion control—the 8V1090.00-2​ combines power density, functional integration, and modular flexibility in a remarkably compact 70.5 × 375 × 235.5 mm enclosure weighing just 4.4 kg.The defining architectural philosophy of the 8V1090.00-2​ is “integration without compromise.” The drive incorporates a C3-class line filter compliant with EN 61800-3, a braking resistor rated for 7 kW peak and 200 W continuous, a 470 µF DC bus capacitor, and an electronic secure restart inhibit function—all within the standard chassis. This integration eliminates the need for external filtering, braking choppers, or auxiliary safety relays, dramatically simplifying cabinet design and reducing total installed cost. Four plug-in module slots on the 8V1090.00-2​ accept optional communication modules (POWERLINK, CAN), encoder interface cards (EnDat 2.2, Hiperface, resolver, incremental/SSI, BiSS), and digital/analog I/O modules, enabling engineers to tailor the drive precisely to application requirements without changing the base hardware platform.Within B&R’s automation ecosystem, the 8V1090.00-2​ is configured and commissioned through the Automation Studio engineering environment, binding seamlessly to B&R’s 8LS, 8LT, and other ACOPOS servo motor families. The drive supports position, speed, and torque control modes with current loop response times as low as 50 µs, delivering the dynamic performance required for high-speed packaging, precision printing, robotic motion, and CNC machining. Its functional safety capability—including Safe Torque Off (STO) compliant with IEC 61800-5-2—makes the 8V1090.00-2​ suitable for export machinery destined for EU markets under the Machinery Directive 2006/42/EC. With a -25°C to +60°C operational temperature range (full load to 40°C, derated above), IP20 protection, and certifications spanning CE, UKCA, cULus, EAC, and KC, the 8V1090.00-2​ is a globally deployable motion control solution that continues to serve as the trusted workhorse for both new machine builds and legacy system maintenance programs.
