The Allen Bradley MPL-A310P-HK74AA Servo Motor is a high-speed MP-Series servo motor developed for industrial machines where responsive movement and repeatable positioning have a direct impact on productivity.
Its 100 mm frame and 25.4 mm magnet stack provide a compact mechanical platform, while the 5000 RPM performance class makes it suitable for high-cycle automated machinery. The 2000-line incremental encoder supports closed-loop servo control, allowing the motion system to monitor actual motor movement during operation.
A notable feature of the HK74AA configuration is its integrated 24 V DC holding brake. This makes the model particularly attractive for applications where an axis needs additional holding capability when the motor is not actively producing torque. Proper brake sequencing remains essential, especially on vertical or load-sensitive axes.
The keyless shaft extension and right-angle rotatable connector also provide useful integration flexibility. These features can simplify the mechanical coupling and cable-routing decisions involved in compact machine designs.
The complete catalog number MPL-A310P-HK74AA should be used when purchasing or replacing the motor. Other MPL-A310P models can have similar dimensions while differing in feedback, shaft, brake, connector, or other configuration details.
For OEMs and industrial automation integrators seeking a compact high-speed servo motor with integrated holding capability, the MPL-A310P-HK74AA provides a well-balanced solution for demanding motion applications.

High-Speed Motion Applications
The Allen Bradley MPL-A310P-HK74AA Servo Motor is an MP-Series low-inertia brushless AC servo motor designed for automated machinery where fast response, repeatable positioning, and controlled high-speed movement are essential.
This 100 mm-frame motor belongs to the 5000 RPM MPL-A310P performance family and uses a 2000-line incremental encoder. Its configuration also includes a keyless shaft extension, right-angle rotatable SpeedTEC DIN connector, and 24 V DC holding brake, making it particularly useful for machine axes where both dynamic response and controlled stopping or holding are important.
Typical applications include:
High-speed packaging equipment
Automated assembly machinery
Indexing and feeding systems
Pick-and-place equipment
Printing and converting machines
Labeling and dispensing systems
Precision material-handling equipment
Automated inspection machinery
High-cycle positioning systems
General industrial motion-control applications
For machines with frequent acceleration, deceleration, and positioning cycles, the low-inertia design can help the servo system respond efficiently to changing motion commands.
Key Performance Benefits
High-speed servo operation
The MPL-A310P-HK74AA is part of the 5000 RPM MPL-A310P family, making it suitable for machinery where rapid rotational movement contributes directly to production speed.
Low-inertia response
The low-inertia motor construction is advantageous for applications requiring frequent changes in speed and direction. It can help the motion axis respond quickly to programmed acceleration and deceleration.
2000-line incremental feedback
The incremental encoder provides the servo drive with motor-position feedback, supporting closed-loop control and repeatable machine movement.
Integrated 24 V DC brake
Unlike brake-free MPL configurations, this model incorporates a 24 V DC holding brake. This can be particularly useful for machine axes where maintaining the motor position after power removal is part of the application design.
Compact 100 mm frame
The 100 mm frame provides a practical mechanical package for automated machinery where installation space is limited but high-speed servo capability is required.
Keyless shaft arrangement
The keyless shaft extension allows the motor to be integrated with compatible couplings without relying on a conventional shaft key.
Flexible connector orientation
The right-angle SpeedTEC DIN connector can be rotated, giving machine builders additional flexibility when routing cables through compact machine structures.
Designed for demanding automation
The combination of high-speed operation, low inertia, encoder feedback, and holding-brake functionality makes this motor a strong candidate for demanding cyclic motion applications.
Technical FAQs
1. What type of servo motor is the MPL-A310P-HK74AA?
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 the MPL-A310P-HK74AA?
This motor belongs to the 5000 RPM MPL-A310P family. Actual operating speed must be established according to the compatible servo drive, load, motion profile, and machine operating conditions.
3. What feedback system does the motor use?
The motor uses a 2000-line incremental encoder for closed-loop feedback. Correct encoder configuration is essential for reliable servo operation.
4. Does this model include a motor brake?
Yes. The MPL-A310P-HK74AA includes a 24 V DC holding brake. The brake should be integrated according to the machine's control and safety requirements rather than treated as a substitute for the servo control system.
5. What can cause the motor to generate a following error?
Excessive load, aggressive acceleration, incorrect servo tuning, mechanical backlash, coupling problems, or unstable feedback can cause the actual motor position to deviate from the commanded position.
6. Why might the motor vibrate during high-speed operation?
Possible causes include mechanical resonance, shaft misalignment, coupling problems, loose mounting, unsuitable control-loop settings, or feedback abnormalities. Both mechanical and electrical factors should be checked.
7. What should be checked if the holding brake does not release?
Verify the brake-control voltage, drive configuration, brake wiring, enable sequence, and mechanical load. The brake should not be forced mechanically to release while the axis is under an uncontrolled load.
8. Why might the motor overheat during repetitive operation?
High continuous torque demand, excessive load inertia, frequent acceleration, insufficient cooling, mechanical resistance, or inappropriate servo tuning can increase motor temperature.
9. What should be checked when the motor does not respond to a motion command?
Check servo enable status, active drive faults, controller commands, feedback condition, motor power connections, safety circuits, brake release conditions, and the selected motion reference.
10. How should a replacement motor be commissioned?
Confirm the complete motor catalog number and drive configuration first. Inspect the mechanical installation, feedback and power wiring, and brake circuit. Perform a controlled enable and low-speed test before gradually validating the normal machine motion profile.
