B&R 8BVI0028HCD0.000-1 ACOPOSmulti 2-Axis Inverter Module

Product Overview

The 8BVI0028HCD0.000-1 (8BVI0028HCD0.000-1) is a high-density 2-axis inverter module developed for the modular ACOPOSmulti drive platform, engineered specifically for cold plate or feed-through mounting environments. By housing two fully independent power inverter stages within a single physical enclosure, this module maximizes power density for multi-axis synchronization in demanding applications such as high-speed robotic assembly, precision packaging arrays, and complex textile machinery. The unit utilizes the modular ACOPOSmulti backplane to integrate directly into the DC bus architecture, facilitating efficient regenerative energy sharing and optimal thermal management in space-constrained industrial control cabinets.

Technical Configuration

This module provides advanced power control through high-speed switching and integrated logic monitoring, suitable for high-demand motion control sequences requiring functional safety.

• Thermal Management: The cold plate or feed-through design allows for direct mounting to liquid-cooled heat sinks or external cabinet surfaces, drastically improving heat dissipation compared to standard air-cooled modules.

• Performance Versatility: With two independent inverter stages, the module supports complex multi-axis motion, while the "AS" (Advanced Safety) configuration provides integrated, dual-channel functional safety.

• Energy Architecture: It features a robust input capacitance of 23.5 microfarads to mitigate voltage ripple, while the internal logic is powered by a stable 25 VDC input feed, ensuring consistent control signal integrity during high-load transients.

• Modular Expansion: Equipped with 2 dedicated slots for plug-in modules, allowing for customized fieldbus, feedback, or technology function integration without increasing the physical footprint.

Technical Specifications

Industrial Hardware FAQs

What is the functional benefit of the "cold plate or feed-through" mounting?

This mounting method is intended for high-density cabinets or environments with high ambient temperatures where natural air convection is insufficient. By transferring heat directly to a liquid circuit or outside the cabinet enclosure, you can achieve higher current density and extended hardware service life, protecting internal components from heat-related premature failure.

How does the integrated "AS" designation impact machine safety?

The "AS" designation denotes Advanced Safety capabilities. This allows the drive to execute safety functions like Safe Torque Off (STO) directly on the drive level, eliminating the need for external safety contactors and reducing the complexity of hard-wired safety logic while maintaining SIL 3 / PL e compliance.

What is the purpose of the 2 slots for plug-in modules?

These slots offer scalability. Depending on your machine requirements, you can insert specific modules to handle different encoder feedback types (like EnDat 2.2 or SSI) or additional communication interfaces, allowing the base inverter to adapt to various automation requirements without replacing the entire drive unit.

Field Commissioning and Safety Guidelines

Thermal Interface Preparation

When utilizing cold plate mounting, ensure the mating surface of the heat sink is perfectly flat and free of debris. Apply a high-thermal-conductivity interface material (TIM) or thermal grease to ensure maximum heat transfer. Tighten all mounting fasteners to the torque specifications provided in the B&R installation manual to prevent air gaps that could cause local hotspots.

DC Bus Connectivity and Torque

The shared DC bus connection is critical for multi-axis performance. Use the factory-specified bus connectors and ensure all bolts are torqued to the correct Nm rating. Loose connections here will lead to increased impedance, voltage drops, and potential DC bus error trips during high-acceleration phases.

Maintenance of Feed-Through Seals

If using feed-through mounting to isolate the power section from the control section (for instance, to pass heat through a cabinet wall), ensure the gasket seals remain intact and airtight. Compromised seals allow conductive dust or moisture into the drive’s internal electronics, which can lead to short circuits or premature module failure.
