B&R ACOPOS Drive Module 8V1045.00-2: The Precision Powerhouse for Agile Industrial Automation

Engineering Excellence in Motion Control

In today's hyper-competitive manufacturing landscape, where machine responsiveness directly correlates with profitability, the B&R ACOPOS Drive Module 8V1045.00-2 delivers uncompromising performance. As the cornerstone of B&R's established ACOPOS system (distinct from ACOPOS P3), this servo drive integrates high dynamic response with exceptional power density. Engineered for applications demanding rapid acceleration and micron-level precision—from semiconductor handling to pharmaceutical production—the 8V1045.00-2 combines 24A peak current delivery with industry-leading 50 μs control cycles. Its modular architecture and native POWERLINK integration enable machine builders to achieve unprecedented synchronization while minimizing energy consumption and cabinet footprint.

Core Technological Innovations

1. Ultra-Fast Motion Control Architecture

• Deterministic Performance: Executes current, speed, and position loops in 50 μs – 3× faster than conventional drives. This enables real-time compensation for load disturbances in high-inertia systems like rotary tables or gantries.

• Nanosecond Synchronization: Leverages POWERLINK's <100 ns jitter for multi-axis coordination, critical for laser cutting registration or electronic cam profiles.

• Adaptive Control Algorithms: Auto-tuning capabilities dynamically adjust to changing mechanical conditions, eliminating manual optimization during product changeovers.

2. Energy-Optimized Power Management

• Regenerative DC Bus: Recaptures 95% of braking energy through ACOPOS's shared bus architecture, reducing net consumption by 15–30% in cyclic operations.

• Thermal Overhead Design: Operates at full 4.4A continuous current (24A peak) in 45°C ambient temperatures without derating, using optimized convection cooling.

• Integrated Braking Management: Onboard 7kW peak/200W continuous braking resistor eliminates external components while enabling emergency stops at 10,000 rpm/s.

3. Future-Proof Modularity
The drive's four-slot expansion interface supports hot-swappable modules for evolving requirements:

• Encoder Flexibility: Direct support for EnDat 2.2, HIPERFACE DSL, BiSS-C, and resolvers via plug-in modules (e.g., 8AC126.60-1).

• Network Adaptability: Interfaces with CANopen, PROFIBUS-DP, or EtherNet/IP using communication modules (8AC110.60-3).

• I/O Customization: 8AC130.60-1 module adds 8 digital I/Os with 53 μs timestamping for event-triggered motions.

Industry-Specific Application Advantages

• Electronics Manufacturing: 50 μs control enables precision placement of SMD components at >25,000 cph with ±5μm repeatability.

• Pharmaceutical Packaging: SIL 3-certified SafeMOTION ensures compliant emergency stops during vial handling while maintaining sterile barrier integrity.

• Textile Machinery: "Flying scissors" synchronization maintains pattern alignment at 2,000 m/min web speeds through adaptive tension control.

• Metal Stamping: Peak current reserves prevent velocity droop during high-torque punching operations, extending tooling life.

Integrated Safety & Connectivity Ecosystem

• Native Functional Safety: Embedded Safe Torque Off (STO), Safe Stop 1 (SS1), and Safe Limited Speed (SLS) meet PL e/SIL 3 without external relays.

• Automation Studio Integration: Unified engineering environment simplifies commissioning with drag-and-drop mapp Motion components for camming or gearing.

• Distributed Topology Support: Seamlessly interfaces with ACOPOSremote drives for decentralized cabinet-free installations near motors.

• Predictive Diagnostics: Continuous monitoring of current signatures detects bearing wear or belt tension issues before failure.
