Description
Product Overview
The GE Fanuc IC693DSM302-AE is a two-axis Motion Mate DSM302 motion control module designed for the GE Fanuc Series 90-30 PLC platform. It combines motion-control processing with PLC logic and communications, providing coordinated control of two servo axes without requiring a separate standalone motion controller. The module uses a dedicated digital signal processor (DSP) for high-speed servo calculations and supports both Standard and Follower operating modes. The IC693DSM302-AE is particularly suited to machine automation applications requiring synchronized positioning, velocity control, and repeatable motion performance.
The IC693DSM302-AE supports GE Fanuc digital AC servos and, from firmware version 1.40 associated with the AE revision, also provides analog-command servo capability. Its servo-loop update rates reach 250 μs for torque, 1 ms for velocity, and 2 ms for position, while block processing is under 5 ms. Automatic data exchange with PLC memory, onboard program storage, position-capture inputs, home/overtravel inputs, and serial programming capability make the GE Fanuc IC693DSM302-AE a practical motion-control component for established Series 90-30 automation systems.

Main Features and Advantages
Two-axis integrated motion control
The IC693DSM302-AE provides coordinated control of two servo axes while operating as an integrated Series 90-30 PLC module. This architecture allows machine sequencing and motion functions to be coordinated through the same PLC-based control system, reducing the need for a separate motion controller.
High-speed servo processing
A dedicated DSP performs motion calculations and servo control. The torque, velocity, and position loops update at 250 μs, 1 ms, and 2 ms respectively, providing the response required for demanding positioning and velocity applications. Block processing is specified at less than 5 ms.

IC693DSM302-AE
Digital and analog servo compatibility
The AE firmware revision introduced analog mode in addition to the original digital servo capability. This allows the module to control suitable GE Fanuc analog-command servos, including applications using SL Series servo equipment, expanding the range of drives that can be integrated with the Series 90-30 platform.
Automatic PLC data exchange
The module can automatically transfer data between PLC tables and the DSM302 without requiring additional user programming for every exchange. This simplifies the interface between machine sequencing logic and motion commands, improving engineering efficiency.
Advanced motion programming
The controller supports one- or two-axis motion programs with synchronized block starts, programmable acceleration, velocity, move, and dwell commands, as well as user scaling. Flash memory provides nonvolatile storage for up to 10 motion programs and 40 subroutines.
Practical machine I/O
Home and overtravel inputs are provided for each servo axis, while position-capture strobe inputs support accurate registration and positioning tasks. Additional 5 V, 24 V, and analog I/O can also be used within the PLC/motion-control architecture.
Application Fields
The GE Fanuc IC693DSM302-AE is primarily used in automated machinery that requires coordinated two-axis motion while retaining Series 90-30 PLC control. Typical applications include material handling equipment, indexing machines, packaging machinery, assembly systems, converting equipment, positioning tables, and automated production stations. Its combination of PLC integration and dedicated servo processing is particularly useful where machine sequence logic and motion commands need to operate closely together.
In manufacturing environments, the module can control two independent servo axes for positioning, feeding, cutting, indexing, or synchronized movement. Home and overtravel inputs provide basic machine-limit supervision, while position-capture inputs can support registration operations such as detecting product marks or synchronizing a mechanical process with an external event.
The IC693DSM302-AE is also useful in robotics-related mechanisms, CNC-type equipment, automated material-handling systems, and specialized OEM machinery. Follower mode can be used when one axis must track a master position signal, while Standard mode provides conventional programmed positioning and velocity control. The high-resolution user-unit ranges allow machine builders to scale motion commands to application-specific engineering units.
For legacy automation systems, the IC693DSM302-AE remains particularly relevant as a maintenance and replacement component for Series 90-30 installations. Its established PLC interface, flash firmware, serial programming connection, and automatic PLC/DSM data exchange can simplify restoration of existing machinery without redesigning the complete control architecture.
