Allen-Bradley 1769-L30ERM CompactLogix Motion Control

Product Overview

The ALLEN-BRADLEY 1769-L30ERM is a versatile CompactLogix 5370 L3 controller designed for small to medium-sized applications requiring integrated motion control and high-speed communication. This high-performance module features 1MB of user memory and comes equipped with a 1GB 1784-SD1 non-volatile memory card for robust data backup. With dual EtherNet/IP ports and support for up to 4 motion axes, the 1769-L30ERM provides a scalable and cost-effective solution for modern automation. Despite its powerful capabilities, the unit maintains a lightweight profile with a net weight of approximately 0.49 kg (1.08 lbs).

Technical Configuration

Advanced Communication & Networking

The 1769-L30ERM features two integrated Ethernet/IP ports with a built-in switch, enabling versatile network topologies including linear and Device Level Ring (DLR). DLR support ensures high network resiliency by providing a recovery path in the event of a single point of failure. The controller also includes a dedicated USB port for easy local programming and diagnostics via the Studio 5000 Logix Designer environment.

Precision Motion Control

Tailored for sophisticated machine control, this 5370 series processor supports 4-axis CIP (Common Industrial Protocol) motion. It includes integrated kinematics functions, allowing for synchronized multi-axis control over EtherNet/IP. This eliminates the need for dedicated motion networks, simplifying system architecture while maintaining high-speed performance for robotics and complex positioning tasks.

Technical Specifications

System Capabilities & Programming

The 1769-L30ERM supports up to 32 concurrent tasks, allowing for efficient organization of complex code. It is fully compliant with IEC 61131-3 languages, including Ladder Logic, Structured Text, and Function Block. For system expansion, the controller can manage up to 8 local I/O modules and supports 3 expansion I/O banks, providing the flexibility needed as production requirements grow. Integrated QoS (Quality of Service) ensures that motion and critical control traffic are prioritized across the network.
