GE IC693APU301 Overview
The GE IC693APU301 Axis Positioning Module (APM) is a single-axis motion control module for the Series 90-30 PLC platform. Originally from GE Fanuc, now under Emerson Automation, this module provides precise servo motor control. Engineers use it to integrate high-performance motion control directly into their PLC system. The module supports both standard and follower modes, offering flexibility for various applications.
Key Technical Specifications
The IC693APU301 controls one motion axis with a servo loop update of 1 millisecond. It features a 25-pin D-shell connector for servo connection and a 24-pin high-density connector for general-purpose I/O. The module includes five LED indicators: EN1, EN2, STST, OK, and CFG. These lights help technicians quickly diagnose module status and communication errors.
Standard vs. Follower Mode
In standard mode, the APM combines PLC logic with high-performance motion control into a single integrated system. The PLC transfers data automatically to the APM, which then controls the axis. In follower mode, the module provides electronic gearing for continuous master-slave applications. This mode supports applications like synchronized conveyors or coordinated motion where one axis follows another.
Compatibility and System Limits
The IC693APU301 works with various CPUs. For CPU 311, 313, and 323, you can install up to three APM modules per system. For CPU 331 and higher, up to eight APM modules are allowed, with a maximum of three modules per baseplate. This scalability lets you expand motion control as needed. The module fits in a single slot and works in any Series 90-30 CPU or expansion baseplate.
Programming and Integration
You develop motion programs using the Motion Programmer software package. Configure the module using VersaPro version 1.1 or later, or Logic-Developer PLC software. The module stores up to ten motion programs. It compares actual axis position to commanded position in real time, ensuring accurate control. The IC693APU301 simplifies troubleshooting by providing dedicated status LEDs.
Cabling Options
Several cables connect the IC693APU301 to drives. Use the IC693CBL311 (10 feet), IC693CBL319 (3 feet), IC693CBL317 (10 feet with shield pigtail), or IC693CBL320 (3 feet with shield pigtail). These short cables with 24-pin I/O connectors maintain signal integrity.
Conclusion
The GE IC693APU301 delivers reliable single-axis motion control for Series 90-30 PLCs. Its dual operating modes, fast servo update, and flexible system limits make it suitable for many automation tasks. By integrating motion control directly into the PLC, this module simplifies system design and improves overall performance.
