Overview
The Allen-Bradley 1398-DDM-009 /A is a single-axis digital servo drive from the Ultra 100 Series family. Ultra 100 drives use microcontrollers to digitally manage motor current, velocity, and position in precision automation applications. This unit is designed for indexing, stepper, velocity servo, and master encoder follower operation, making it suitable for a wide range of motion control tasks.
Key Features
- Digital Motion Control: Microprocessor-based control for current, velocity, and position management
- Flexible Configuration: Supports indexing, velocity servo, stepper, and encoder-following operation modes
- Multiple Control Interfaces: Compatible with analog, digital, step/direction, quadrature encoder, and optional DeviceNet networking
- Integrated Diagnostics: 3-level LED status display with fault detection for system troubleshooting
- Compact Design: Space-efficient form factor suitable for OEM integration and retrofit installations
- Factory-Programmed Motor Compatibility: Pre-loaded with parameters for multiple brushless servo motor families (F, H, N, W, Y series)

- I/O Power Supply: 12–24V DC external (required for digital I/O)
- Weight: 5.51 lbs
- Series Designation: Ultra 100 (discontinued by manufacturer 07/30/2010)
Typical Applications
The 1398-DDM-009 excels in motion control scenarios requiring repeatable positioning and speed regulation:
- Indexing and rotary positioning in packaging and assembly machinery
- Web tension control and speed regulation in converting operations
- Material handling and conveyor speed control
- Stepper and servo-based automation in OEM equipment
- Master-follower encoder synchronization tasks
Compatibility & Replacements
This drive is equivalent to Reliance/Electrocraft DDM-009 and other Ultra 100 variants. The 1398-DDM-009 is functionally compatible with brushless servo motors in the F, H, N, W, and Y series families. Configuration and commissioning are performed via serial host commands or optional Ultra Master software. For modern equivalent performance, consider the Kinetix 6500 series as a forward-compatible successor. All settings and motor parameters are factory-installed; external commissioning tools or firmware downloads may be required for customization or updates.
