Compatible Replacement & Equivalent Models
When the 1398-DDM-009 is discontinued, obsolete, or unavailable through standard channels, the following models are commonly evaluated as replacements or functional equivalents. Compatibility depends on your motor, feedback device, and control architecture — always verify before substitution.
- Allen-Bradley 1398-DDM-019 — Higher current (19 A) variant in the same ULTRA 100 family; direct form-factor replacement for higher-torque applications
- Allen-Bradley 2098-DSD-005X — ULTRA 3000 Series digital servo drive; modern replacement with enhanced diagnostics and Logix integration
- Allen-Bradley 2098-DSD-010X — ULTRA 3000 Series, 10 A continuous; closest current-rating equivalent with expanded communication options
- Allen-Bradley 2097-V33PR6 — Kinetix 300 Series; suitable for standalone EtherNet/IP-based motion control upgrades
- Siemens SINAMICS S120 — Cross-brand alternative for multi-axis applications requiring modular architecture
- Yaskawa SGDV Series — Third-party equivalent for cost-sensitive replacements; requires motor and feedback re-mapping
Important: Cross-brand substitutions require engineering validation. Contact Konmask.com for application-specific compatibility assessment.
Why Choose the Original 1398-DDM-009
- Proven field reliability — Thousands of units deployed globally in continuous production environments

- Established spare parts supply chain — Konmask.com maintains stock of tested, refurbished, and new-surplus units
Typical Applications
- CNC machine tool axis control (X/Y/Z positioning)
- Packaging line pick-and-place servo systems
- Printing and converting machine web tension control
- Semiconductor wafer handling and precision positioning
- Robotics joint actuation in legacy automation cells
- Textile machinery spindle and traverse drives
- Assembly line conveyor indexing and synchronization
System Compatibility
The 1398-DDM-009 is designed to operate within the following Rockwell Automation control architectures:
- PLC-5 Systems — Via 1771-QA or 1771-QB servo interface modules
- SLC 500 Systems — With 1746-HSRV high-speed servo module
- ControlLogix / CompactLogix — Through SERCOS or analog motion modules
- Compatible Motors: Allen-Bradley 1326AB and 1326AS series servo motors (verify nameplate current rating against drive output)
- Feedback Devices: Incremental encoders (1024 PPR standard); resolver feedback requires additional interface module
Selection Guide
Use the following criteria to determine whether the 1398-DDM-009 is the right drive for your application, or to select the most appropriate replacement:
- Step 1 — Confirm motor current rating: The 1398-DDM-009 supports up to 9 A continuous. If your motor nameplate exceeds this, consider the 1398-DDM-019 (19 A) or ULTRA 3000 2098-DSD-010X.
- Step 2 — Verify input power: Confirm 115 VAC or 230 VAC single-phase availability at the panel. Three-phase applications require a different drive family.
- Step 3 — Check feedback type: Incremental encoder is standard. Resolver or absolute encoder feedback requires an interface module or a different drive model.
- Step 4 — Assess communication requirements: If EtherNet/IP or DeviceNet integration is required, upgrade to ULTRA 3000 or Kinetix series.
- Step 5 — Evaluate obsolescence risk: The 1398 series is mature/end-of-life. For new machine builds, Konmask.com recommends evaluating ULTRA 3000 or Kinetix 300/350 as forward-compatible alternatives.
Quality Assurance & Sourcing
All Allen-Bradley 1398-DDM-009 units supplied by Konmask.com undergo a rigorous multi-stage quality process:

Replacement & Compatibility FAQ
- Q: Is the 1398-DDM-009 still in production?
- A: The 1398 ULTRA 100 Series has reached end-of-life status with Rockwell Automation. Konmask.com supplies new-surplus and professionally refurbished units to support legacy installations.
- Q: Can I replace a 1398-DDM-009 with a 2098-DSD-010X directly?
- A: Not as a direct drop-in. The ULTRA 3000 series uses a different connector pinout, parameter structure, and may require updated motion programming in your controller. Engineering review is recommended.
- Q: What motors are compatible with the 1398-DDM-009?
- A: The drive is designed for Allen-Bradley 1326AB and 1326AS series servo motors. Third-party motors may be compatible if current ratings and encoder specifications match — contact us for verification.
- Q: Do you provide a warranty on refurbished units?
- A: Yes. All tested and refurbished 1398-DDM-009 units carry a 90-day functional warranty covering manufacturing defects and premature failure under normal operating conditions.
