Product Description:

The 8V1045.00-2 is an AC servo drive from B & R Automation and forms part of the 8V1 ACOPOS Servo Drives series. It regulates three-phase servo motors by modulating the DC bus into high-frequency pulse sequences, letting machine builders synchronize position, velocity, and torque across multiple axes. By converting line power into a controlled output, the unit becomes a core motion component in packaging, printing, and material-handling cells.

This model uses a 24 VDC control supply with a tolerance of ±25%. It provides continuous output of 4.4 Aeff and can deliver 24 Aeff for short intervals. The gap between these envelopes allows quick acceleration of inertial loads without oversizing the cabinet supply, and internal thermal models prevent sustained overcurrent events. The steady mechanical limit is 2 kW. A 235 µF DC-bus capacitor restrains voltage sag, and start-up draws 7 A of inrush current before the pre-charge circuit stabilizes. The housing is 70.5 mm wide, 235.5 mm deep, 375 mm high, and weighs 4.1 kg. Four slots accept plug-in modules for network or feedback expansion. The isolated control feed keeps logic active during brief mains interruptions.

For dynamic axis control, the inverter section can produce output frequencies up to 598 Hz, and its IGBT bridge switches at a nominal 20 kHz, reducing audible noise and improving current fidelity. A sizable input capacitance of 8200 µF smooths the rectified mains so that the installed load can reach a maximum of 5 kVA without compromising DC-link stability. Thermal design relies on the metal baseplate coupling to the cabinet rail, and spacing is simplified by the drive's slender form factor. Routine service involves checking the DC-link capacitors and ensuring acceptable ripple and temperature margins during machine power cycles.
