The Allen Bradley MPL-A310P-MJ72AA Servo Motor is engineered for industrial motion systems where fast response and dependable positioning are central to machine performance.
As part of the MP-Series MPL low-inertia family, this motor combines a compact 100 mm frame with a 25.4 mm magnet stack and 5000 RPM speed rating. This combination is well suited to automated machinery that performs rapid, repetitive movement.
One of the defining characteristics of the MJ72AA configuration is its multi-turn high-resolution absolute encoder. Compared with a basic single-turn feedback arrangement, multi-turn absolute feedback is particularly useful when the motion system needs detailed position information over multiple motor revolutions.
The motor also features a keyed shaft extension, making it compatible with suitable keyed mechanical couplings, while the right-angle SpeedTEC DIN connector can be rotated to help accommodate different cable-routing arrangements.
The model is supplied without a motor brake. For vertical axes, suspended loads, or other applications requiring mechanical holding, the machine designer should provide an appropriate external braking or holding mechanism.
The complete catalog number MPL-A310P-MJ72AA should be used when sourcing or replacing the motor. Other MPL motors may have the same frame size but different feedback, speed, shaft, connector, or brake configurations.
For OEMs and industrial automation integrators looking for a compact, high-speed servo motor with absolute multi-turn feedback, the MPL-A310P-MJ72AA offers a strong solution for demanding motion applications.

High-Speed Precision Motion Applications
The Allen Bradley MPL-A310P-MJ72AA Servo Motor is an MP-Series low-inertia brushless AC servo motor designed for industrial automation systems that demand fast acceleration, accurate positioning, and repeatable high-speed motion.
This configuration features a 100 mm frame, 25.4 mm magnet stack, 5000 RPM rated speed, and multi-turn high-resolution absolute encoder feedback. It also uses a keyed shaft extension and a right-angle SpeedTEC DIN connector with 180-degree rotational flexibility. The motor is configured without an integrated brake.
Its combination of low inertia and high-speed operation makes it a strong fit for machines where short cycle times and precise repetitive movement are important.
Typical applications include:
High-speed packaging machinery
Automated assembly systems
Indexing and feeding equipment
Pick-and-place machines
Printing and converting equipment
Labeling and dispensing systems
Precision material handling
Automated inspection machinery
Electronic assembly equipment
General industrial motion-control systems
For machines performing repeated acceleration, deceleration, and positioning sequences, this servo configuration provides a practical platform for responsive closed-loop motion.
Performance and Integration Advantages
High-speed motion capability
The 5000 RPM rating makes the MPL-A310P-MJ72AA appropriate for applications where rapid rotational movement is an important part of the machine cycle.
Low-inertia response
The MPL-Series low-inertia construction allows the motor to respond quickly to changes in commanded speed and position, making it particularly useful for repetitive motion.
Multi-turn absolute feedback
The high-resolution multi-turn encoder provides absolute position information across multiple motor revolutions. This can be valuable in applications where accurate axis position must be maintained and tracked through complex machine movements.
Compact 100 mm frame
The 100 mm frame size gives machine designers a compact servo option for equipment where available installation space is limited.
Keyed shaft extension
The keyed shaft provides a familiar mechanical interface for compatible couplings and transmission components, making integration straightforward for many industrial machine designs.
Flexible connector orientation
The right-angle SpeedTEC DIN connector can be rotated through 180 degrees, providing useful flexibility for cable routing around the motor and machine structure.
Brake-free configuration
This model does not include an integrated motor brake. Applications requiring mechanical holding during power loss should therefore provide a suitable external holding mechanism.
Built for demanding automation
The combination of high speed, low inertia, absolute multi-turn feedback, and compact construction makes this motor particularly attractive for high-cycle production machinery.
Technical FAQs
1. What type of servo motor is the MPL-A310P-MJ72AA?
It is an Allen Bradley MP-Series MPL low-inertia brushless AC rotary servo motor designed for industrial motion-control applications.
2. What is the rated speed of this servo motor?
The MPL-A310P-MJ72AA has a 5000 RPM rated speed, making it suitable for high-speed automated motion applications.
3. What type of feedback does the motor use?
This model uses a multi-turn high-resolution absolute encoder. The feedback system provides the servo controller with detailed position information for closed-loop motion control.
4. What is the benefit of multi-turn absolute feedback?
Multi-turn feedback allows the control system to track position across multiple revolutions rather than only within a single motor revolution. This can be especially useful for positioning axes with extended travel or complex motion profiles.
5. Does the MPL-A310P-MJ72AA have an integrated brake?
No. This model uses a no-brake configuration. If the application requires positive holding when servo power is removed, an appropriate external mechanical holding solution should be provided.
6. What can cause a following error during high-speed operation?
Excessive load inertia, aggressive acceleration, unsuitable servo tuning, mechanical backlash, coupling problems, or feedback abnormalities can cause the actual motor position to deviate from the commanded position.
7. Why might the motor vibrate at certain speeds?
Potential causes include mechanical resonance, shaft misalignment, coupling problems, loose mounting, load characteristics, or inappropriate control-loop settings. Both the mechanical transmission and servo parameters should be checked.
8. What should be checked if the absolute feedback signal is abnormal?
Inspect the feedback cable, connector seating, drive configuration, encoder power, grounding, and communication status. A damaged or improperly connected feedback circuit can prevent correct servo operation.
9. What should be checked when the motor overheats?
Review continuous torque demand, load inertia, duty cycle, acceleration frequency, cooling conditions, mechanical resistance, and servo tuning. Persistent overheating generally indicates that the complete motion system needs further evaluation.
10. How should a replacement MPL-A310P-MJ72AA be commissioned?
Confirm the exact catalog number and compatible servo-drive configuration first. Check mechanical alignment, motor power, feedback wiring, grounding, and controller parameters. Start with a controlled low-speed test before validating the complete production motion profile.
