Ultra 100 Servo Drive 1398-DDM-005-A: High-Performance Digital Drive for Precision Motion

Technical Specifications

Main Features and Advantages

The Allen-Bradley 1398-DDM-005-A​ excels through its advanced digital architecture and application flexibility. Its core is a powerful digital signal processor (DSP) executing Field-Oriented Control algorithms. This provides exceptionally smooth, low-cogging torque production even at very low speeds, which is critical for precise positioning and velocity regulation. The drive’s “Universal” nature is a key advantage; a single 1398-DDM-005-A​ module can be configured via software to match the electrical parameters (resistance, inductance, back-EMF constant) of a wide range of brushless servo motors. This drastically simplifies spares inventory and provides design flexibility, allowing engineers to select the optimal motor for the mechanical load without being constrained by a specific drive model.Superior Performance and Integration: The 1398-DDM-005-A​ offers high bandwidth current control, enabling rapid torque response to dynamic load changes. It supports high-resolution feedback devices, allowing for precise position and velocity control. Its standard SERCOS (Serial Real-time Communication System) fiber optic interface provides deterministic, noise-immune communication with a motion controller, enabling tightly synchronized multi-axis coordination. The drive features extensive programmable I/O for interfacing with machine sensors and controllers, and includes sophisticated auto-tuning routines that simplify commissioning and optimize performance for the connected motor and load. Protective features are comprehensive, including models for motor thermal protection. The modular design of the Ultra 100 system allows the Allen-Bradley 1398-DDM-005-A​ to be paired with shared DC bus power supplies and various feedback option modules, creating a compact, efficient, and scalable motion control solution. This combination of high performance, configurability, and system integration makes it a preferred choice for complex, high-speed automation machinery.

Application Field

The Allen-Bradley 1398-DDM-005-A​ Ultra 100 Universal Drive is engineered for high-performance motion control applications where speed, precision, and synchronization are non-negotiable. In the packaging machinery industry, it is extensively used on high-speed vertical form-fill-seal (VFFS) machines, cartoners, and labeling systems. Here, the 1398-DDM-005-A​ provides the precise torque and velocity control needed for accurate film indexing, product placement, and label application at high cycle rates, directly impacting throughput and reducing material waste.Within the printing and converting sector, this drive is critical for web tension control, print cylinder registration, and rotary knife cut-off applications. Its smooth, low-speed torque performance ensures consistent tension, while its high dynamic response allows for instantaneous corrections to maintain perfect registration between colors or process steps. The Allen-Bradley 1398-DDM-005-A​ is also a cornerstone in semiconductor manufacturing equipment, such as wire bonders and die attach machines, where micron-level positioning accuracy and rapid point-to-point moves are essential. Similarly, in automated assembly and robotics, the drive controls precise positioning arms, spindle heads for screwdriving, and synchronized transfer lines. Its ability to operate as part of a multi-axis SERCOS ring makes the 1398-DDM-005-A​ ideal for complex machinery with several coordinated servo axes, such as flying shears, rotary tables, and gantry systems, where precise electronic gearing or cam profiling is required to achieve complex motion trajectories and high productivity.
