Description:
The B&R 8V1045.00-2 is a single-axis ACOPOS 1045 brushless servo drive engineered by B&R Industrial Automation as the mid-range member of the modular ACOPOS servo family, designed to operate synchronous and induction servo motors from a 3×400–480 VAC supply. Delivering 2 kW of continuous output power at 4.4 A RMS (24 A peak) with a 20 kHz IGBT power stage, the 8V1045.00-2 combines an integrated line filter, integrated braking resistor and electronic restart inhibit in a single cabinet-mount housing that accepts four application-specific plug-in modules for network, encoder and I/O expansion.
Application Scenarios:
Consider a packaging OEM rebuilding a high-speed horizontal wrapper where the cross-seal jaw, product infeed and film-tension nip all demand precisely synchronized servo motion from a cabinet that has no room left to spare. Legacy drive cabinets for this machine type typically stack a discrete drive, a braking resistor, a line reactor and a separate encoder card for each axis — inflating wiring labour and spare-parts variety. By standardizing on the 8V1045.00-2 as the axis drive, the engineering team consolidates all of that into one 70.5 mm-wide housing: the braking resistor is already inside, the EN 61800-3 C3 line filter is already inside, and the encoder interface is simply a plug-in module selected to match the feedback on the chosen servo motor. This is exactly the role the 8V1045.00-2 was engineered for — it turns a single servo axis from a multi-component cabinet exercise into one modular, pluggable drive block, addressing the classic pain points of cabinet congestion, inconsistent axis behaviour and slow fault isolation on high-speed packaging, printing and handling machinery.
