1398-DDM-005-DN Overview
A digital servo drive is a closed-loop amplifier that precisely regulates current, velocity, and position in a brushless or brush-type servo motor using real-time feedback from an encoder or resolver. As part of the broader motion control hierarchy, a servo drive sits between a motion controller (PLC or standalone indexer) and the motor, translating low-level command signals into high-bandwidth PWM output stages that drive the motor windings. The Universal Drive category denotes multi-mode operation - the same hardware can be commanded as a torque loop, velocity loop, or position loop, simplifying spare-parts stocking for machine builders.
Key features of this drive include a Universal Drive architecture with DeviceNet network connectivity (the '-DN' suffix), 500 W continuous output power, 7.5 A peak current for acceleration transients, and digital torque/velocity/position loop closure. The unit is part of the ULTRA 100 Series' discontinued product family from Allen-Bradley (Rockwell Automation), with Discontinued-by-Manufacturer status announced 2010-07-29, though service continues through authorized repair channels. Programming is performed via the 1398-HMI-001 TouchPad or Ultra Master software running on a host PC.
The internal topology combines a rectified single-phase front end, a DC bus capacitor bank, and a PWM inverter stage driving the motor windings. Encoder feedback is decoded for commutation and velocity/position loop closure. The DeviceNet interface (DN option) allows the drive to be commanded and monitored on a CAN-based industrial network, integrating with ControlLogix, SLC 500, and PLC-5 controllers using DeviceNet scanner modules.
Typical applications for the 1398-DDM-005-DN include CNC machining retrofits, packaging lines, indexing tables, textile winding machines, and laboratory automation where a flexible, networked axis is required. In replacement scenarios the drive is widely used to maintain legacy equipment that originally shipped with this specific catalog number. When designing with this device, note the 500 W power ceiling - upgrading to higher-power axes (1 kW or more) requires the -009 or -019 models of the same family. The 7.5 A peak provides headroom for short acceleration bursts but is not a continuous rating; sizing should be done on RMS thermal current.

Typical Applications
1398-DDM-005-DN is suitable for 6 applications: CNC Machining Center Retrofit, Packaging Line Indexing Axis, Textile Winding and Tension Control, Laboratory Automation and Test Stands, Automated Inspection Camera Positioning, HVAC Damper and Valve Actuator Drive.
CNC Machining Center Retrofit
The 1398-DDM-005-DN drives legacy CNC machining centers where 500 W of axis power and 7.5 A peak current deliver adequate torque for spindle and feed-axis retrofits on small to mid-size mills. With DeviceNet communication, the drive integrates directly into Allen-Bradley ControlLogix or PLC-5 controllers used in mature CNC installations. Programming is performed through Ultra Master software, with the optional 1398-HMI-001 TouchPad providing local diagnostics during commissioning. Compared to modern Kinetix drives, the 1398-DDM-005-DN is favored for hot-swapping worn-out units without rewiring the cabinet, since it shares the same footprint, terminal block, and encoder wiring as the original ULTRA 100 hardware. The 7.5 A peak headroom is well-matched to cutting-load transients on aluminum and mild-steel workpieces below 1 kW.
Recommended
Packaging Line Indexing Axis
The 1398-DDM-005-DN drives indexing tables and conveyor positioning axes on packaging lines where a compact, networkable servo axis at 500 W provides precise index repeats at cycle rates typical of horizontal-form-fill-seal machines. The DeviceNet (-DN) interface allows the packaging PLC to command position setpoints and read drive status without analog wiring, simplifying panel layout. Position-mode operation closed over the motor encoder achieves repeatable index accuracy within one encoder count, sufficient for bottle-filling and label-applicator stations. The drive's 7.5 A peak is well-suited to accelerate/decelerate indexing masses against product-loading transients. For new packaging lines Kinetix drives are preferred, but the 1398-DDM-005-DN remains the lowest-effort replacement on legacy lines where cabinet wiring must remain untouched.
Recommended
Textile Winding and Tension Control
The 1398-DDM-005-DN provides torque-mode operation for winding and tension-control applications in textile plants, where its 500 W continuous rating matches small-diameter winders used for thread and filament packages. The DeviceNet interface lets a supervisory PLC adjust torque setpoints and read actual current over a single network cable, eliminating analog drift that traditionally plagues tension loops. The ULTRA 100 drive's 7.5 A peak handles the brief torque transients encountered during package build-up and doff transitions. Engineers retrofitting older textile machinery benefit from the drive's identical pinout to its predecessor units, avoiding full cabinet rewiring. The discontinued status as of 2010 means spare units must be sourced from legacy channels, but the unit remains mechanically and electrically identical to its original release for the life of the machine.
Recommended
Laboratory Automation and Test Stands
The 1398-DDM-005-DN drives small-axis motion in laboratory automation rigs and test stands, where 500 W continuous power covers most small XYZ tables, syringe pumps, and dispensing heads. Its compact ULTRA 100 form factor fits laboratory enclosures without exhausting cabinet space, and DeviceNet communication allows programmatic axis control from a host PC running Ultra Master or a SCADA-style interface. The ability to operate in torque mode simplifies force-feedback test rigs, while position mode covers repeatable dispense patterns. For modern labs the same drop-in family offers the 1398-DDM-005X-DN with built-in indexer, removing the requirement for an external motion controller. The device's legacy support ecosystem - including repair services from Radwell and York Scientific - keeps it serviceable for institutional labs long past the 2010 discontinuation.
Recommended
Automated Inspection Camera Positioning
The 1398-DDM-005-DN drives pan-and-tilt stages on machine-vision inspection stations, where its 500 W power and 7.5 A peak current adequately position camera mounts above conveyors and rotary index tables. Position-mode operation achieves the precise angular repeatability required for multi-camera inspection arrays, while DeviceNet integration lets a vision PLC synchronize drive motion with camera triggers on a single industrial network. The drive's small panel footprint simplifies mounting inside vision-cabinet enclosures where space is at a premium. For inspection systems already deployed with ULTRA 100 drives, replacing failed units with the 1398-DDM-005-DN requires no mechanical rework, which is critical on production lines that cannot tolerate extended downtime. The 2010 discontinuation has not slowed this replacement use-case because no other vendor offers a pin-compatible equivalent.
Recommended
HVAC Damper and Valve Actuator Drive
The 1398-DDM-005-DN applies to large HVAC damper and process-valve actuator duty in building automation retrofits, where its 500 W continuous output matches mid-size modulating damper actuators in clean-room and pharmaceutical facilities. The DeviceNet option integrates natively into building-automation networks descended from Niagara or Johnson Controls front-ends, allowing setpoint and feedback data to traverse the drive without analog conditioning. Torque-mode operation provides clean hold-position behavior without the chatter that pneumatic actuators exhibit at low flows. Engineers maintaining legacy Allen-Bradley building-automation systems find the 1398-DDM-005-DN is the least disruptive replacement option because terminal blocks and encoder pin assignments match the original wiring diagrams exactly. Its continued availability through legacy channels makes it a practical service part for facilities operating with installed ULTRA 100 controls.

Key Differentiators
- Catalog suffix disambiguation - only -DN variant provides DeviceNet networking (vs 1398-DDM-005 (base analog/indexer model without DN))
- Higher-power upgrade path inside same family (vs 1398-DDM-009-DN)
- Stand-alone indexer for PLC-free operations (vs 1398-DDM-005X-DN)
Design Notes
Estimated: The 1398-DDM-005-DN draws single-phase 100-240 V AC at 50/60 Hz to deliver 500 W continuous output. At unity input power factor the input current is approximately 500 W / (240 V x 1) ~= 2.1 A rms and proportionally higher at 120 V line (~4.2 A rms). Confirm branch-circuit protection and wire gauge against the ULTRA 100 Installation Manual, since the drive has internal DC-bus capacitors that draw high inrush at power-on.
The 7.5 A rating is peak output current for acceleration transients only. Thermal sizing must use the motor's continuous RMS current (typically 3-5 A for a 500 W axis). Operating the drive at the 7.5 A peak for more than a few seconds triggers thermal foldback and will shorten component life. Always program motion profiles with torque limits that respect the motor's continuous rating.
Mount the drive vertically in a cabinet with at least 100 mm of clearance above and below for airflow; the ULTRA 100 chassis relies on natural convection plus internal fan for cooling. Avoid mounting directly above heat-generating equipment such as line reactors, since the drive's ambient rating is typically 0-50C with derating above 40C. The DeviceNet cable must use the prescribed DeviceNet mid-physical-layer cable (typically thick or thin trunk) to maintain the 500 kbps / 250 kbps signaling budget.
Verify the catalog number suffix carefully: 1398-DDM-005 is the analog/indexer base model, 1398-DDM-005-DN adds DeviceNet, and 1398-DDM-005X-DN adds both DeviceNet and indexer capability. Substitution beyond suffix differences (e.g. -009 vs -005 power stages) requires mechanical and wiring verification. Lifecycle: this part was discontinued on 2010-07-29 - confirm spare stock before commissioning a new line that relies on it.
Compliance Information
Compliance certifications such as RoHS and REACH were not found in the verified web data for this legacy drive; built in 1999-2010 era before many of these became standard. This is an industrial motion-control product, not automotive, so AEC-Q100 does not apply.
