The Allen Bradley MPL-A310P-MK72AA Servo Motor is designed for industrial motion applications where rapid response and accurate position control are essential.
Its MP-Series MPL low-inertia construction combines a 100 mm frame size with a 25.4 mm magnet stack and 5000 RPM rated speed. This makes the motor suitable for automated machinery that performs frequent acceleration, deceleration, indexing, and positioning.
A defining feature of the MK72AA configuration is its multi-turn high-resolution absolute encoder. This feedback arrangement provides detailed position information over multiple motor revolutions and can be advantageous in applications where the controller needs reliable axis-position information during complex machine movement.
The motor uses a keyless shaft extension, allowing integration with appropriate couplings and mechanical transmissions. The right-angle SpeedTEC DIN connector can also be rotated through 180 degrees, providing useful flexibility for cable routing in compact machine structures.
The model is supplied without an integrated brake. Machine designers should therefore consider external holding or braking arrangements where the application involves vertical loads, suspended mechanisms, or other axes that must remain mechanically secured when servo power is removed.
The complete catalog number MPL-A310P-MK72AA should be used when purchasing or replacing the motor. Other MPL-Series motors may share the same frame size while having different speed, feedback, shaft, connector, or brake configurations.
For OEMs and system integrators seeking a compact high-speed servo motor with multi-turn absolute feedback, the MPL-A310P-MK72AA provides a strong solution for demanding automated motion systems.

The motor should be installed on a rigid mounting surface with accurate shaft alignment and an appropriate coupling. Power and feedback cables should be routed to minimize mechanical stress and interference. Because this configuration has no integrated brake, the machine's external holding strategy should also be verified during commissioning.

High-Speed Precision Motion Applications
The Allen Bradley MPL-A310P-MK72AA Servo Motor is an MP-Series low-inertia brushless AC servo motor designed for industrial machinery requiring fast response, accurate positioning, and repeatable high-speed motion.
This configuration combines a 100 mm frame size, 25.4 mm magnet stack, 5000 RPM rated speed, and multi-turn high-resolution absolute encoder feedback. It also features a keyless shaft extension, right-angle rotatable SpeedTEC DIN connector, and a no-brake configuration.
This combination makes the motor well suited to high-cycle machinery where rapid acceleration, controlled deceleration, and accurate multi-revolution positioning are important.
Typical applications include:
High-speed packaging equipment
Automated assembly machinery
Indexing and feeding systems
Pick-and-place machines
Printing and converting equipment
Labeling and dispensing machinery
Precision material-handling systems
Automated inspection equipment
Electronic production machinery
General industrial motion-control systems
For equipment with demanding production cycles, the low-inertia design can help the motion system respond quickly to frequent changes in speed and position.
Motion-Control Advantages
5000 RPM high-speed capability
The MPL-A310P-MK72AA is designed for high-speed servo applications where rapid motor rotation and short machine cycles are important.
Low-inertia response
The low-inertia construction allows the motor to respond quickly to changes in commanded movement, making it suitable for repetitive acceleration and deceleration.
Multi-turn absolute feedback
The integrated multi-turn high-resolution encoder provides absolute position information across multiple motor revolutions. This is particularly useful for positioning systems requiring detailed axis-position information.
Compact 100 mm frame
The 100 mm frame size offers a practical solution for machine builders who need high-performance servo motion within a relatively compact mechanical envelope.
Keyless shaft extension
The keyless shaft arrangement provides flexibility when selecting compatible couplings and mechanical transmission components.
Rotatable right-angle connector
The SpeedTEC DIN connector uses a right-angle arrangement and can be rotated through 180 degrees, giving engineers more freedom when planning motor cable routing.
No integrated brake
The MK72AA configuration does not include a motor brake. For vertical axes or applications requiring positive holding after power removal, an appropriate external holding mechanism should be included in the machine design.
Absolute-positioning capability
The multi-turn feedback configuration makes this motor particularly attractive for applications where position tracking over several revolutions is important to machine operation.
Technical FAQs
1. What type of motor is the MPL-A310P-MK72AA?
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 motor?
The MPL-A310P-MK72AA is rated for 5000 RPM, making it suitable for high-speed automated motion applications.
3. What feedback technology is used?
The motor uses a multi-turn high-resolution absolute encoder, providing detailed position feedback across multiple motor revolutions.
4. What advantage does multi-turn absolute feedback provide?
It allows the motion system to track position over multiple revolutions rather than only within one revolution. This can be valuable for long-travel positioning, indexing, and coordinated machine axes.
5. Does the MPL-A310P-MK72AA include a holding brake?
No. This model is configured without an integrated brake. Applications requiring mechanical holding should incorporate a suitable external braking or load-retention solution.
6. What could cause a following error during rapid acceleration?
Excessive load inertia, aggressive acceleration settings, incorrect servo tuning, mechanical backlash, coupling problems, or feedback abnormalities can cause the actual position to deviate from the commanded position.
7. Why might the motor vibrate at a particular speed?
Possible causes include mechanical resonance, shaft misalignment, coupling problems, mounting conditions, load characteristics, or unsuitable control-loop parameters.
8. What should be checked if the absolute encoder feedback becomes unstable?
Inspect the feedback cable and connectors, drive configuration, encoder power, grounding, and feedback status. Any interruption or abnormality in the feedback circuit can affect servo operation.
9. How can excessive motor temperature be investigated?
Check the continuous load torque, acceleration frequency, duty cycle, mechanical resistance, cooling conditions, and servo tuning. The complete motion profile should be reviewed if overheating occurs repeatedly.
10. What is the recommended commissioning procedure?
Confirm the exact motor and compatible servo-drive configuration first. Check mounting, shaft alignment, motor power, feedback wiring, grounding, and controller parameters. Perform controlled low-speed testing before validating the full production motion profile.
