Product Details

MPL-B310P-MJ72AA Product Description

The Allen-Bradley MPL-B310P-MJ72AA is a medium-power rotary servo motor engineered for seamless integration within Rockwell Automation's MPL Series motion control architecture. Designed to operate in concert with Kinetix servo drives and the Logix control platform, this motor delivers precise torque output, high-resolution feedback, and deterministic motion response across demanding industrial environments. Its system-matched design ensures that engineers can deploy it within existing control cabinets, multi-axis gantry systems, and coordinated motion cells without requiring additional signal conditioning or mechanical adaptation. The MPL-B310P-MJ72AA is built to sustain continuous duty cycles in manufacturing, packaging, material handling, and process automation applications where motion accuracy and system uptime are non-negotiable.

Within a complete Rockwell Automation control architecture, the MPL-B310P-MJ72AA does not operate in isolation. It functions as the execution layer component that receives velocity and torque commands from the Kinetix 5700 or Kinetix 6500 servo drive, which in turn receives coordinated motion instructions from a ControlLogix or CompactLogix controller over the EtherNet/IP network. This layered architecture — spanning the control layer, drive layer, motor layer, and feedback layer — ensures that every motion profile is executed with microsecond-level synchronization. The motor's integrated multi-turn encoder provides absolute position feedback directly to the drive, eliminating the need for external encoders or resolver modules and reducing wiring complexity within the control cabinet.

Signal integrity across the motion system is maintained through the use of shielded motor power cables and feedback cables rated for continuous flexing in cable track applications. When paired with a 2198-H003-ERS3 or 2198-H008-ERS3 Kinetix 5700 single-axis drive module, the MPL-B310P-MJ72AA benefits from integrated safe torque-off (STO) functionality, enabling compliance with SIL 2 and PLd safety architectures without external safety relays. The drive's integrated bus sharing architecture further allows multiple axes to share a common DC bus, reducing panel space and improving energy efficiency across multi-axis machine designs.

From a communications perspective, the Kinetix drive interfacing with the MPL-B310P-MJ72AA connects to the ControlLogix backplane via a 1756-M08SE or 1756-M16SE servo module, or communicates directly over EtherNet/IP using the integrated network port on Kinetix 5700 drives. This eliminates the need for a dedicated motion network and allows motion, I/O, and safety data to share a single EtherNet/IP infrastructure. The 1756-EN2T or 1756-EN2TR EtherNet/IP communication module in the ControlLogix chassis provides the network backbone, while the 1756-L85E or 1756-L83E ControlLogix controller executes the motion program using Logix Designer software.

For I/O integration, digital and analog signals from sensors, limit switches, and proximity detectors are collected through 1756-IB16 or 1756-OB16 I/O modules mounted in the ControlLogix chassis or distributed via 1734 POINT I/O modules on EtherNet/IP. This distributed I/O architecture reduces home-run wiring and allows I/O nodes to be placed close to the machine, improving signal quality and reducing installation time. The MPL-B310P-MJ72AA's motion axis is fully coordinated with these I/O signals through the Logix controller's integrated motion and I/O scan engine, enabling precise cam profiling, registration control, and electronic gearing without external motion controllers.

Power distribution to the MPL-B310P-MJ72AA system is managed through a 2198-DBRxx dynamic braking resistor module and a 2198-P031 or 2198-P070 Kinetix 5700 power supply module, which conditions incoming three-phase AC power and provides regulated DC bus voltage to all connected drive modules. Upstream power protection is provided by a 140M motor protection circuit breaker or a 1492-SPM supplementary protector, ensuring that the servo system is protected against overcurrent, short circuit, and phase loss conditions. A 1606-XLP power supply provides 24 VDC logic power to the control system, I/O modules, and HMI devices.

Operator interface and system visualization are handled by a PanelView Plus 7 or PanelView 5510 HMI terminal connected to the EtherNet/IP network, providing real-time axis status, fault diagnostics, and motion parameter visualization. Maintenance engineers can use the Logix Designer Studio 5000 software to perform online axis tuning, view encoder feedback in real time, and execute motion test routines without interrupting production. The integrated diagnostic capability of the Kinetix drive — including axis fault codes, thermal status, and bus voltage monitoring — reduces mean time to repair and supports predictive maintenance strategies.

The MPL-B310P-MJ72AA is stocked and available for immediate shipment. Each unit undergoes pre-shipment functional testing to verify encoder integrity, winding resistance, and insulation resistance before dispatch. A 12-Month Warranty covers all units against manufacturing defects, with technical support available for system integration, axis configuration, and commissioning assistance.

The MPL-B310P-MJ72AA is designed for deployment within a fully integrated Rockwell Automation platform. In a typical multi-axis machine cell, the motor operates alongside a Kinetix 5700 2198-H008-ERS3 single-axis drive module, coordinated by a 1756-L85E ControlLogix controller executing motion profiles in Studio 5000 Logix Designer. The control chassis is populated with 1756-EN2TR EtherNet/IP communication modules for redundant network connectivity and 1756-IB16 digital input modules for machine interlock and sensor integration. A 2198-P031 Kinetix 5700 power supply conditions the DC bus shared across multiple drive axes, while a 2198-DBR40P dynamic braking resistor manages regenerative energy during deceleration cycles. Distributed I/O is handled via 1734-AENT POINT I/O EtherNet/IP adapters mounted at machine stations, reducing home-run wiring. Operator control is provided through a PanelView Plus 7 2711P-T12W21D8S HMI terminal, with system visualization and axis diagnostics displayed in real time. A Stratix 5700 1783-BMS10CGL managed industrial Ethernet switch provides the network infrastructure connecting all EtherNet/IP devices. Upstream power protection is ensured by 140M-C2E-B40 motor protection circuit breakers, and 24 VDC logic power is supplied by a 1606-XLP95E power supply module. This integrated platform ensures that the MPL-B310P-MJ72AA operates within a fully coordinated, diagnostics-capable, and scalable automation architecture.

The MPL-B310P-MJ72AA servo motor is deployed across a wide range of industrial sectors where precise motion control and system integration are critical.
