Product Overview

The Allen-Bradley 2094-BM02-S is a high-performance axis module engineered for the Kinetix 6000 multi-axis servo drive system. This module is designed to deliver precise motion control for synchronous motor applications, offering a compact footprint that integrates directly onto a Kinetix 6000 power rail. A standout feature of the 2094-BM02-S is its integrated Safe Torque Off (STO) functionality, which is certified to meet SIL 3 and PLe safety standards, ensuring that motor torque is removed safely during emergency scenarios without disconnecting the power to the entire drive system.

Operating within a 400V-class system, this module converts DC bus power into precisely regulated AC output for servo motors. It is optimized for high-dynamic applications where rapid acceleration and tight velocity regulation are required. Although officially discontinued by the manufacturer on June 30, 2016, this module remains a critical component for maintaining existing ControlLogix-integrated motion systems.

Technical Characteristics

• Safety Integration: Features built-in Safe Torque Off (STO) to prevent unexpected motor restarts, improving operator safety and reducing machine downtime during maintenance.

• Dynamic Performance: Supports a 500 Hz velocity loop bandwidth and a 1300 Hz current loop frequency, enabling high-speed responsiveness and sub-millisecond control updates.

• Peak Enhancement: Includes peak current enhancement capabilities, allowing the module to handle momentary loads from 150% up to 250% of rated current for high-torque starts.

• Energy Efficiency: Operates at a high thermal efficiency of 98%, minimizing heat load within the control cabinet.

• Compact Rail Mounting: Designed for the Kinetix 6000 "IAM/AM" architecture, allowing multiple axis modules to share a common DC bus and reducing wiring complexity.
