Product Overview
The AMCI AMCI-7264 is a single-slot, high-performance PLC module that provides absolute position feedback from a resolver. Designed to seamlessly integrate with a host PLC system, such as Rockwell Automation’s Allen-Bradley ControlLogix and CompactLogix platforms, the AMCI-7264 serves as a vital link between the physical machine and the control system. A resolver is an electromechanical sensor that provides a highly robust and reliable position signal, and the AMCI-7264 converts this analog signal into a precise digital position value for the PLC. Unlike incremental encoders, which lose position data upon power loss, a resolver with the AMCI-7264 provides an absolute position, ensuring that the control system always knows the exact location of the machine axis, even after an emergency stop or power cycle. This module is a cornerstone for applications requiring precise, repeatable, and non-volatile position data.
Technical Specifications
Main Features and Advantages
The AMCI AMCI-7264 module offers several key features that provide significant advantages in industrial automation. Its most compelling attribute is its reliance on resolver technology for position sensing. Resolvers are electromechanical devices known for their extreme durability and immunity to harsh industrial conditions such as dirt, oil, high temperatures, and vibration. This robustness ensures reliable operation in environments where optical encoders might fail. The module provides true absolute position feedback. This means the AMCI-7264 reports the exact position of the machine axis immediately upon startup, without needing to perform a homing sequence. This capability is critical for safety and efficiency in machinery that requires immediate, accurate position data.
Seamless Integration: The AMCI-7264 is designed for easy integration with Rockwell Automation’s ControlLogix and CompactLogix platforms. It is a single-slot module that fits directly into the PLC chassis, and its configuration is handled entirely within the standard programming software, such as Studio 5000. This tight integration simplifies engineering, reduces wiring complexity, and allows for direct access to position data in the PLC’s tag database. The module also features a high update rate and high resolution, enabling the precise control and accurate data logging required for high-speed and complex motion applications. Its reliable performance and ease of use make the AMCI-7264 a superior choice for position-sensing applications.
Application Field
The AMCI AMCI-7264 is extensively used in a wide variety of industrial machinery applications that require precise and reliable absolute position feedback. Its primary application fields are in machine building and manufacturing, including stamping and forming presses, packaging machinery, converting equipment, and material handling systems. In these applications, the AMCI-7264 is used to monitor the position of a machine’s main shaft, a cam, or a linear actuator. For instance, in a stamping press, the AMCI-7264 ensures that the press ram is always in the correct position relative to the die, which is essential for both product quality and machine safety. In packaging lines, it can track the position of a conveyor or a robotic arm to ensure precise product placement and sealing. The module’s robust design makes it particularly suitable for the harsh environments often found in heavy manufacturing and food processing. The non-volatile, absolute position data provided by the AMCI-7264 eliminates the need for recalibration after power cycles, thereby reducing startup time and improving overall machine uptime.

Installation and Maintenance
Pre-installation preparation: Before installing the AMCI AMCI-7264, ensure the PLC chassis is de-energized. Verify that the correct software, such as Studio 5000, is installed and configured for the specific PLC. The AMCI-7264 is a single-slot module that plugs directly into a spare slot in the chassis. Connect the resolver to the module’s front connector, ensuring the wiring is correct according to the module’s documentation. The resolver must be mounted and aligned correctly on the machine to provide accurate feedback. All wiring should be secured to prevent damage from vibration.
Maintenance recommendations: Routine maintenance for the AMCI-7264 is minimal. The module is solid-state and has no moving parts. The primary maintenance tasks involve periodically checking the integrity of the resolver’s cable and connectors for any signs of wear, damage, or loose connections. Since the resolver itself is a durable electromechanical device, it typically requires little to no maintenance. Any required configuration changes, such as modifying the resolution or scaling, can be performed through the PLC’s programming software. The module’s internal diagnostics can be monitored within the PLC to ensure its continuous and reliable operation.
