Module d'entraînement servo multiple ACOPOS 8V1090.00-2 B&R

Product Overview

The 8V1090.00-2 (8V1090002) is a high-performance inverter module from the B&R ACOPOSmulti series, engineered for precise motion control in highly dynamic industrial environments. Designed to operate within a modular drive system, this servo drive provides the necessary intelligence and power to control brushless synchronous motors with extreme accuracy. In industries such as high-speed printing, plastic injection molding, and robotic palletizing, the 8V1090.00-2 acts as a critical node in the motion network, offering rapid response times and integrated safety functions. Its compact, book-format design allows for side-by-side mounting on a common DC bus, which not only saves significant cabinet space but also enables energy exchange between motoring and braking axes, dramatically improving overall machine efficiency.

Technical Configuration

The 8V1090.00-2 is part of the ACOPOSmulti family, utilizing a sophisticated hardware architecture that supports both POWERLINK and standard fieldbus communication. This module is designed for vertical installation on a mounting plate, featuring a standardized interface for encoder feedback and digital I/O. The "Multi" architecture allows it to draw power from a shared DC bus supplied by a central power supply module, simplifying the wiring of multi-axis systems. Internally, the drive features high-resolution current control and hardware-based protection circuits against overvoltage, overcurrent, and thermal overload. The 70.5 mm width profile (Size 1/2) is optimized for high-density cabinet layouts without compromising on heat dissipation or electrical performance.

Technical FAQs

Can the 8V1090.00-2 be used in a single-axis application?

While the 8V1090.00-2 is optimized for the modular ACOPOSmulti system (sharing a DC bus), it can function in a standalone capacity if provided with the appropriate DC bus voltage and power supply module from the B&R catalog.

What is the benefit of the modular DC bus connection?

The shared DC bus allows the 8V1090.00-2 to "reuse" energy generated by other braking motors in the system. This reduces the heat dissipated by braking resistors and lowers the total energy consumption of the machine.

What encoder types are supported by this drive?

The 8V1090.00-2 supports a wide variety of feedback systems, including EnDat, Resolver, and SinCos, through the use of modular plug-in cards. This allows for maximum flexibility when matching the drive to different motor brands and precision requirements.

Is it possible to mount these drives horizontally?

No. For proper thermal management and airflow, the 8V1090.00-2 must be mounted vertically. Horizontal mounting will obstruct the internal cooling path and lead to premature thermal shutdown or hardware failure.

Engineering & Installation Guide

• DC Bus Shielding and Grounding: When connecting the 8V1090.00-2 to the common DC bus bar, ensure the bus mounting screws are tightened to the specified torque. Proper grounding of the mounting plate is essential; use a low-impedance connection to the central ground point to prevent EMI interference with sensitive encoder signals.

• Motor Cable Requirements: Always use high-quality, shielded motor cables. The shield must be connected to the drive's EMC shield plate using a 360-degree clamp. To prevent ground loops, ensure the motor housing is also correctly bonded to the machine frame. Keep motor cables as short as possible to minimize capacitive leakage current.

• Airflow and Clearance: To maintain the rated performance, provide a minimum clearance of 100 mm above and below the drive module. Since the 8V1090.00-2 uses forced air cooling, check that the air intake at the bottom and the exhaust at the top are completely unobstructed. Periodically inspect the internal fan for dust accumulation in heavy industrial environments.
