Allen-Bradley 2198-P070 Servo Drive Power Supply

Product Details

2198-P070 Product Description

The Allen-Bradley 2198-P070 is a system-ready DC-bus power supply engineered for the Kinetix 5700 multi-axis servo drive platform. Designed to deliver stable, high-current DC bus power across multiple servo axes, the 2198-P070 serves as the foundational power layer in demanding motion control architectures. Its role extends beyond simple power conversion — it actively participates in bus sharing, regenerative energy management, and system-level fault coordination, making it an indispensable component in high-performance manufacturing, packaging, and process automation environments. Every unit is supplied with a 12-Month Warranty and is validated for Contextual Integration within Allen-Bradley Kinetix 5700 control architectures.

The 2198-P070 is not a standalone component — it is the power backbone of a coordinated Kinetix 5700 servo system. In a typical multi-axis motion control cabinet, the 2198-P070 feeds a shared DC bus that simultaneously powers multiple Kinetix 5700 dual-axis inverter modules such as the 2198-D032-ERS3 and 2198-D057-ERS3, enabling synchronized motion across gantry, conveyor, and rotary axis configurations without individual AC rectification per axis. This shared-bus topology dramatically reduces cabinet footprint, simplifies wiring, and improves energy efficiency through regenerative braking energy redistribution.

At the control layer, the 2198-P070 operates under the command of a CompactLogix 5380 or ControlLogix 5580 controller communicating via EtherNet/IP with CIP Motion protocol. The controller issues coordinated motion commands through the Studio 5000 Logix Designer environment, where axis parameters, bus voltage thresholds, and fault response behaviors are configured. The 2198-P070 reports bus voltage status and fault conditions back to the controller in real time, enabling closed-loop power management at the system level.

On the I/O and safety layer, the system integrates 1734 POINT I/O modules for distributed digital and analog signal acquisition, while safety functions are enforced through GuardLogix safety controllers or integrated safe-torque-off (STO) channels within the Kinetix 5700 inverter modules. The 2198-CAPMOD-2240 capacitor module may be added to the DC bus to extend ride-through capability during momentary power interruptions, protecting both the 2198-P070 and downstream inverter modules from nuisance faults.

For communication infrastructure, the system relies on a Stratix 5700 or Stratix 5400 managed industrial Ethernet switch to maintain deterministic EtherNet/IP traffic between the controller, HMI, and servo drives. At the HMI layer, a PanelView Plus 7 terminal provides operators with real-time axis status, bus voltage monitoring, and alarm acknowledgment. Power distribution upstream of the 2198-P070 is typically managed through a 1606-XLP or 1606-XLS series 24 V DC power supply for control circuit logic, while the main AC feed is protected by appropriately rated circuit breakers and line reactors to limit harmonic distortion and protect the power supply input stage.

This fully integrated architecture — spanning the 2198-P070 power supply, Kinetix 5700 inverter modules, CompactLogix/ControlLogix controller, POINT I/O, Stratix switch, and PanelView HMI — delivers a cohesive, scalable, and diagnostically transparent motion control platform suitable for high-cycle industrial applications.

Packaging & Material Handling: In high-speed packaging lines, the 2198-P070 powers multiple servo axes controlling film feed, sealing jaws, and product indexing. The shared DC bus enables regenerative energy from decelerating axes to be reused by accelerating axes, reducing net energy consumption and heat dissipation within the control cabinet.

Automotive & Discrete Manufacturing: Robotic welding cells and assembly transfer lines rely on the 2198-P070 to maintain stable bus voltage across six or more coordinated servo axes. The active front-end design ensures low harmonic distortion on the plant power grid, meeting IEEE 519 compliance requirements common in automotive manufacturing facilities.

Printing & Converting: Web tension control and register correction in printing presses demand sub-millisecond torque response. The 2198-P070's high-current DC bus output supports the fast dynamic response of Kinetix 5700 inverter modules, ensuring print registration accuracy at high line speeds.

Food & Beverage Processing: Washdown-rated control cabinets housing the 2198-P070 and associated Kinetix 5700 modules are deployed in portioning, filling, and capping lines. The system's integrated diagnostics reduce unplanned downtime by providing early warning of bus voltage anomalies before they escalate to production-stopping faults.

Mining & Heavy Industry: In conveyor drive systems and ore processing equipment, the 2198-P070 supports high-inertia load management through its regenerative capability, feeding braking energy back to the bus rather than dissipating it through braking resistors, extending component life and reducing thermal management requirements.

Q1: How many Kinetix 5700 inverter axes can the 2198-P070 support on a shared DC bus? The 2198-P070 provides 70 A of continuous DC bus current. The number of supported axes depends on the combined continuous current demand of all connected inverter modules (e.g., 2198-D032-ERS3, 2198-D057-ERS3). Allen-Bradley's Motion Analyzer software should be used to perform a full bus loading calculation, accounting for duty cycle, regenerative contributions, and peak demand overlap. Typically, four to eight axes can be supported depending on axis sizing.

Q2: Is the 2198-P070 compatible with existing ControlLogix and CompactLogix motion applications, and what firmware is required? Yes. The 2198-P070 is fully compatible with ControlLogix 5580 and CompactLogix 5380 controllers running Studio 5000 Logix Designer v30 or later with CIP Motion enabled. The Kinetix 5700 drive firmware must be at a compatible revision as specified in Rockwell Automation's product compatibility and download center (PCDC). Contextual Integration with existing motion programs is straightforward — the power supply appears as a bus supply axis object within the Logix project and requires no additional programming beyond bus configuration parameters.

Q3: What is covered under the 12-Month Warranty, and what is the typical lead time for in-stock units? The 12-Month Warranty covers manufacturing defects, component failures under normal operating conditions, and functional non-conformance to published specifications. It does not cover damage resulting from incorrect installation, overvoltage events beyond rated input, or unauthorized modification. In-stock units are available for immediate shipment following pre-shipment functional testing, which includes DC bus output verification, input rectifier integrity check, and communication interface validation. Lead time for stocked units is typically 1–3 business days for standard destinations.
