Allen-Bradley 1398-DDM-009 Ultra 100 Servo Drive – 1 kW Single Phase

Brand Allen-Bradley

Model Allen-Bradley 1398-DDM-009

Product Overview

The Allen-Bradley 1398-DDM-009 is a digital servo drive belonging to the ULTRA 100 Series, a family of universal digital drives designed for precise motion control applications. As a compact, single-axis servo drive, the Allen-Bradley 1398-DDM-009 digitally manages current, velocity, and position loops using microcontroller-based control algorithms, ensuring repeatable performance and eliminating the element drift associated with analog control systems . The drive delivers 1 kW continuous output power (1.5 HP) with a peak current of 15 A, making it well-suited for single-phase systems operating between 100 and 240 VAC at 50/60 Hz .

Positioned as a versatile motion control solution, the Allen-Bradley 1398-DDM-009 supports multiple operating modes including indexing, velocity servo, stepper emulation, and master encoder following . The drive’s fully digital architecture enables configuration via Windows-based Ultra Master software, allowing quick setup, commissioning, and troubleshooting . The Allen-Bradley 1398-DDM-009 requires an external 12-24 VDC power source for its I/O logic, while the main power stage operates directly from single-phase AC line power without requiring an external transformer .

As part of the now-discontinued ULTRA 100 product line, the Allen-Bradley 1398-DDM-009 remains a critical spare component for facilities maintaining legacy servo systems. Its compact design, comprehensive interface options, and proven reliability continue to make it a sought-after drive for industrial motion control applications .
