Description

1. Product Title

B&R 8V1045.00-2 – ACOPOS 1045 Series 2kW Single Axis Modular Servo Drive

2. Product Overview

The 8V1045.00-2 is a discontinued high-performance single-axis servo drive from B&R classic ACOPOS modular drive platform, rated 2kW for 3×400~480V AC three-phase industrial power supply. It adopts highly integrated all-in-one design: built-in C3 grade EMC mains filter, integrated dynamic braking resistor, electronic safe restart inhibit safety circuit, which greatly reduces external cabinet wiring and peripheral safety components. Equipped with 4 rear plug-in expansion slots, users can freely insert communication cards (POWERLINK, EtherCAT, CANopen, Ethernet) and encoder feedback modules (EnDat, Hiperface, resolver, incremental encoder) to match synchronous/asynchronous servo motors. Ultra-short control loop cycle ensures outstanding dynamic response for electronic cam, gantry synchronization, CNC interpolation, winding tension control and high-speed repetitive positioning. Manufacturer official end-of-life, only new surplus and fully tested refurbished units available on the market.
