B&R ACOPOS Drive Module 8V1640.00-2: High-Power Precision for Demanding Industrial Automation

Redefining Performance in Heavy-Duty Motion Control

In the realm of industrial automation where power density, energy efficiency, and uncompromising reliability intersect, the B&R ACOPOS Drive Module 8V1640.00-2 stands as a technological cornerstone. Engineered for high-torque applications demanding 32 kW continuous power and 64A current delivery, this servo drive transcends conventional capabilities by integrating regenerative energy management, multi-axis synchronization, and functional safety into a unified architecture. As part of B&R's proven ACOPOS platform—distinct from the newer ACOPOS P3 series—it delivers micron-level precision in CNC machining, high-speed packaging, and heavy material handling while reducing total cost of ownership through innovative energy recapture and modular scalability.

Core Engineering Innovations

1. Advanced Power & Energy Architecture

• High-Current Delivery: Supports 64A continuous current (200A peak) at 400–480V AC input, enabling direct control of high-inertia loads like industrial presses or extruder screws without derating.

• Regenerative DC Bus System: Captures 95% of deceleration energy through shared-bus topology, redistributing it to accelerating axes—reducing net energy consumption by 15–30% in cyclic operations versus traditional drives15.

• Integrated Braking Management: Features a 7kW peak / 0.2kW continuous onboard braking resistor, eliminating external components while handling emergency stops at 10,000 rpm/s.

2. Precision Control & Synchronization

• Triple-Loop Control: Executes position, speed, and torque loops with 50µs cycle times, achieving ±5-arc second repeatability in rotary stages and <10µm linear positioning accuracy.

• Multi-Axis Coordination: Synchronizes up to 8 axes via POWERLINK with <100ns jitter, critical for electronic line shafting in printing presses or synchronous conveyors.

• Adaptive Vibration Suppression: DSP-based algorithms dynamically damp mechanical resonances from 10 Hz to 1.2 kHz, eliminating settling delays in gantry systems.

3. Safety & Reliability Systems

• SIL 3/PL e Functional Safety: Embedded SafeMOTION functions (STO, SOS, SLS) enable hardware-locked shutdown in <4ms, eliminating external safety relays.

• Restart Interlock: Prevents unintended activation after power failure—mandating manual reset to avoid hazardous restarts14.

• Thermal Resilience: Maintains full output at 50°C ambient using predictive thermal modeling, with derating alerts triggered 30 minutes before potential overload.

4. Hyper-Modular Integration

• Expandable I/O Slots: Two slots support plug-in modules for legacy encoders (EnDat 2.2, resolvers), safety protocols (PROFIsafe), or high-speed I/O with 53µs timestamping.

• Unified DC Bus Segments: Connect up to 8 drives to a common DC link, enabling centralized power supplies and 40% reduction in cabling complexity.

Conclusion: The High-Power Automation Catalyst

The B&R ACOPOS 8V1640.00-2 redefines heavy-duty motion control by merging 32 kW power density with sub-100ns synchronization—a combination previously unattainable in single-drive units. Its integrated DC bus architecture transforms energy waste into operational savings, while SIL 3 safety systems eliminate external relay labyrinths. Unlike modular ACOPOS P3 systems, this legacy ACOPOS variant excels in applications requiring raw power delivery, such as metal stamping presses or mining conveyors, where 200A peak current ensures uninterrupted operation under shock loads.

For OEMs designing machinery with >10 kW axes, the drive’s adaptive thermal management enables continuous duty in 50°C ambient temperatures, while its hybrid expandability (via CANopen, POWERLINK, or I/O modules) protects investments in existing motor fleets. When paired with Automation Studio, engineers deploy complex multi-axis routines 40% faster than with traditional platforms. In an era of escalating energy costs and precision demands, the 8V1640.00-2 isn’t merely a drive—it’s the cornerstone of sustainable, high-performance industrial systems.
