Allen-Bradley 2198-P070 – Kinetix 5500 Shared DC Bus Power Supply | Rockwell Automation
Engineering Background
The Allen-Bradley 2198-P070 is a dedicated shared DC bus power supply module engineered for the Kinetix 5500 servo drive platform by Rockwell Automation. It provides a regulated, high-current DC bus to multiple axis modules within a common bus configuration, enabling coordinated multi-axis motion control with centralized power management. This architecture is the industry standard for high-throughput manufacturing lines requiring synchronized servo motion.
Product Positioning
Designed for demanding industrial automation environments, the 2198-P070 serves as the power backbone for Kinetix 5500 multi-axis servo systems. It is the preferred choice for OEMs and system integrators building packaging machinery, CNC machining centers, material handling conveyors, and precision assembly lines where axis count, power density, and bus stability are critical engineering parameters.

Proven Application Environments
- Packaging Machinery: Multi-axis form-fill-seal, cartoning, and palletizing lines requiring synchronized servo motion and high regenerative energy handling.
- CNC Machining Centers: High-speed spindle and feed axis coordination with stable DC bus voltage under rapid load transients.
- Material Handling & Conveyors: Coordinated multi-zone conveyor systems with shared bus energy recovery between braking and accelerating axes.
- Printing & Converting: Web tension control and registration systems demanding sub-millisecond torque response.
- Semiconductor & Electronics Assembly: Precision pick-and-place and wafer handling requiring ultra-low velocity ripple.
- Automotive Body & Powertrain Assembly: High-duty-cycle servo presses and transfer lines with peak power demands up to 216 A DC.
Engineering Advantages
- Shared DC Bus Architecture: Enables energy regeneration between axes — braking axes feed accelerating axes, reducing net energy consumption and eliminating the need for individual power supplies per axis.
- EtherNet/IP Integration: Native EtherNet/IP port allows full diagnostic visibility, parameter configuration, and predictive maintenance data collection via Studio 5000 or FactoryTalk.
- High Power Density: 70 kW continuous output in a compact panel-mount form factor reduces cabinet footprint versus equivalent multi-supply configurations.
- Seamless Logix Integration: Add-On Profiles (AOPs) and pre-built Studio 5000 routines accelerate commissioning and reduce engineering hours.
- Robust Thermal Management: Integrated thermal monitoring with automatic derating protects the module and connected axis drives under sustained high-load cycles.
- Scalable Bus Expansion: Compatible with 2198-Sxxx axis modules across the Kinetix 5500 family, supporting 2 to 8+ axes on a single shared bus rail.
System Architecture & Signal Flow
The 2198-P070 connects to a three-phase AC supply and converts it to a regulated 650 V DC bus distributed via the Kinetix 5500 shared bus rail connector to all axis modules in the group. The EtherNet/IP port connects to the Logix controller backplane network for coordinated motion commands. The internal shunt circuit dissipates excess regenerative energy; for high-inertia applications, an external regenerative resistor (catalog 2097-Rx) can be wired to the dedicated terminals. The module reports bus voltage, current, temperature, and fault status in real time to Studio 5000 for HMI display and historian logging.

Technical FAQ
Q: Can the 2198-P070 operate on 480 V AC input?
A: No. The 2198-P070 is rated for 195–264 V AC (200/208/240 V AC systems). For 480 V AC applications, refer to the 2198-P141 or 2198-P208 models.
Q: How many Kinetix 5500 axis modules can one 2198-P070 support?
A: The number of axes depends on the total continuous power draw of all axis modules. At 70 kW continuous, it typically supports 4–8 axes depending on motor sizing. Consult Rockwell’s Motion Analyzer tool for exact sizing.
Q: Is an external regenerative resistor required?
A: The internal shunt handles moderate regenerative loads. For high-inertia or frequent deceleration applications exceeding the internal shunt rating, an external regenerative resistor (2097-Rx series) is recommended.
Q: What firmware version is required on the Logix controller?
A: Studio 5000 Logix Designer v21.00 or later is required. Verify AOP version compatibility with your specific controller firmware revision.
Q: Can I mix 2198-P070 with Kinetix 5700 axis modules?
A: No. The 2198-P070 is exclusively compatible with the Kinetix 5500 (2198-Sxxx) axis module family. Kinetix 5700 uses the 2198-Pxxx-ERS3 power supply series.
