Product Description:

B & R Automation’s 8V1090.00-1 belongs to the 8V1 ACOPOS Servo Drives series and functions as a compact, panel-mounted servo inverter. The unit converts the DC link of the machine’s power system into precisely timed three-phase output, allowing synchronous or induction motors to track motion profiles commanded by the controller. By closing current and velocity loops inside the drive, it supports high-bandwidth positioning tasks in packaging, materials-handling, and assembly machines while keeping cabling and enclosure space to a minimum.

The drive can deliver up to 4 kW of shaft power, and its DC bus and heat sink are sized so this rating can be sustained without derating. When supplied from a 400 V line it provides a continuous phase current of 8.8 Aeff; under a 480 V supply the continuous value falls to 6.6 Aeff because the higher voltage produces the same power at lower current. Short mechanical transients are handled by a peak output of 24 Aeff, and commissioning events draw a 20 A starting current that must be allowed for in circuit protection. The installed apparent power reaches 10 kVA, so branch conductors and fusing have to meet this demand. All live parts are designed for Overvoltage Category II, indicating compatibility with low-voltage industrial distribution networks.

The internal braking resistor dissipates regenerative energy continuously at 200 W and can absorb peaks up to 7 kW during rapid deceleration, reducing the need for external dump modules. A switching frequency ceiling of 10 kHz lets users trade acoustics for efficiency within drive settings. The housing carries a IP20 rating, so it requires installation in a closed control cabinet. Mechanical dimensions are 70.5 mm wide, 375 mm high, and 235.5 mm deep, with a transport weight of 4.4 kg, allowing dense multi-axis layouts without exceeding common panel depth constraints.
