Product Description:

The 8V1090.00-2 is an AC servo drive manufactured by B&R Automation for the 8V1 ACOPOS Servo Drives series. It converts 400 VAC mains power into a regulated three-phase output for brushless motors used in automated handling, packaging, and assembly stations. Integrated brake control, a DC bus link, and modular communication options allow the unit to coordinate multiple axes inside a compact control cabinet. Because the drive manages power conversion and brake actuation in one enclosure, it suits multi-axis systems where short response time and orderly cabinet integration are important.

A continuous phase current of 8.8 Aeff supports sustained motion, while peak demand can reach 24 Aeff during acceleration. The drive supports loads up to the rated output of 4 kW, and its DC link stores energy in a 470 µF capacitor bank that smooths regenerated power. Pulse-width modulation occurs at a 10 kHz nominal switching frequency, allowing an output frequency ceiling of 598 Hz for high-speed spindle or linear motor operation. The unit supports up to 10 kVA of installed load, permits motor leads up to 25 m, and limits starting inrush at 400 VAC to 7 A. An auxiliary transistor supplies 1 A for motor brake release, four plug-in module slots accept I/O or fieldbus cards, and the housing measures 235.5 mm in depth and 375 mm in height.

A dedicated resistor path can dissipate braking energy at a peak of 7 kW, preventing DC bus overvoltage during rapid deceleration. The aluminum housing weighs only 4.4 kg, and its slim front dimension of 70.5 mm conserves panel width when drives are mounted side by side. The narrow housing also helps maintain orderly cable routing in dense cabinets, and the low mass reduces mounting load without affecting the drive layout. These dimensions are useful where several drives must share the same backplate and ventilation path.
