Product Overview

The 8V1090.00-2 is a compact single-axis servo drive from B&R classic ACOPOS series, designated ACOPOS 1090 for 4kW rated motor output, widely adopted in high-precision automated machinery industry. This unit integrates an EMC-compliant mains filter and internal braking resistor inside the housing, eliminating extra external accessories and simplifying cabinet wiring layout while suppressing grid harmonic interference effectively. It reserves four expansion slots to extend functional safety modules, multi-channel encoder interfaces and analog/digital I/O boards, easily meeting SIL 3 and PL e safety requirements for press machinery, lifting equipment and robot axes. Real-time POWERLINK bus enables ultra-fast synchronous linkage with B&R X20 series PLC controllers, delivering outstanding dynamic performance for electronic gearing, cam profiling, CNC interpolation and multi-axis coordinated motion tasks. The robust hardware protection system cuts off drive pulses immediately once detecting overcurrent, over-temperature or wiring faults to protect servo motors and power components from damage.
