Allen-Bradley MPL-B560F-MK72AA Servo Motor: Complete Product Guide

1. Product Overview

The MPL-B560F-MK72AA is a high-performance low-inertia brushless rotary servo motor belonging to the MP-Series MPL servo motor family. It is designed for industrial motion-control applications where accurate positioning, fast acceleration and deceleration, stable speed regulation, and repeatable operation are important.

This model is a 480 V-class / 460 V armature-voltage servo motor with a 165 mm frame size, 152.4 mm magnetic stack length, and a rated speed of 3000 rpm. It uses a high-resolution absolute multi-turn encoder for feedback, allowing the motion-control system to maintain accurate position information during machine operation.

The motor uses a keyless shaft extension, a right-angle SpeedTEC DIN connector, and a connector arrangement that can be rotated through 180 degrees. The motor is supplied without an integrated holding brake, making it particularly suitable for applications where the mechanical load does not require a motor-mounted brake.

The low-inertia design is especially useful for machinery that needs rapid changes in speed and direction. Compared with a high-inertia motor, a low-inertia servo motor can respond quickly to commands from the servo drive, which can improve machine cycle time and dynamic positioning performance.

For replacement purposes, it is therefore not recommended to select a motor solely because the frame size appears identical. The complete catalog number should be checked.

---

5. Product Description

The MPL-B560F-MK72AA is designed as a precision servo motor for automated machinery. Its low-inertia rotor construction enables rapid response to changes in the command signal.

In a conventional motor application, the motor may primarily be expected to provide continuous rotation. In a servo application, however, the motor is part of a closed-loop motion system. The controller sends a motion command to the servo drive, the drive supplies controlled current to the motor, and the encoder continuously provides feedback about motor position and movement.

The MPL-B560F-MK72AA is therefore more than a simple rotating motor. It forms part of a complete motion-control system in which speed, position, acceleration, deceleration, and torque are actively controlled.

The integrated multi-turn absolute feedback is particularly useful for machines requiring accurate position information. Multi-turn feedback can maintain information about the motor’s angular position across multiple revolutions, which is valuable in positioning applications where repeatability and absolute position are important.

---

6. Main Features

6.1 Low-Inertia Construction

One of the most important characteristics of the MPL-B560F-MK72AA is its low-inertia design.

Low rotor inertia allows the motor to accelerate and decelerate rapidly. This is particularly useful for machinery with frequent starts, stops, indexing operations, direction changes, and short machine cycles.

Typical examples include packaging machinery, indexing equipment, electronic assembly equipment, machine tools, material handling systems, and automated production equipment.

---

6.2 3000 rpm Rated Speed

The motor is configured for a rated speed of approximately 3000 rpm.

This speed range provides a practical balance between torque production and rotational speed for many industrial motion applications. It allows the motor to support relatively fast mechanical movement while maintaining the characteristics required for servo control.

---

6.3 High-Resolution Absolute Multi-Turn Feedback

The integrated high-resolution multi-turn absolute encoder is one of the major advantages of this motor.

Feedback allows the servo drive to determine the motor’s position and speed. In a closed-loop system, this information is continuously compared with the commanded motion.

This enables the control system to compensate for deviations and maintain precise machine movement.

For equipment manufacturers, absolute multi-turn feedback can also simplify machine homing and positioning strategies, depending on the overall control architecture.

---

6.4 Keyless Shaft

The MPL-B560F-MK72AA uses a keyless shaft extension.

A keyless configuration can simplify certain mechanical coupling arrangements and can be useful where the machine designer uses a suitable clamping hub, coupling, or other compatible mechanical connection.

The coupling method should always be selected according to the required torque, speed, shaft diameter, axial/radial loads, and manufacturer’s mechanical requirements.

---

6.5 180° Rotatable Right-Angle Connector

The motor uses a right-angle SpeedTEC DIN connector arrangement with 180° rotational capability.

This is useful when installation space is restricted. Cable direction can be better matched to the machine layout, which may reduce interference with guards, frames, cable tracks, and neighboring components.

---

6.6 No Integrated Brake

The MPL-B560F-MK72AA is supplied without an integrated motor brake.

This configuration is suitable when the application does not require a holding brake or when the machine uses an alternative mechanical holding solution.

For vertical axes or loads that must remain stationary when power is removed, the absence of a motor brake should be considered carefully during machine design.

---

7. Product Applications

The MPL-B560F-MK72AA is particularly suitable for industrial equipment requiring accurate, repeatable and dynamically controlled rotary movement.

7.1 Packaging Machinery

Packaging machines frequently require rapid acceleration and deceleration.

The low-inertia design of this motor can be beneficial for indexing, cutting, feeding, sealing, labeling and positioning mechanisms.

For example, an automated packaging machine may need the motor to accelerate quickly, reach a controlled speed, stop at a precise position, and immediately repeat the cycle. Servo control allows these operations to be coordinated accurately.

---

7.2 Machine Tools

Servo motors are widely used in machine tools where positioning accuracy and repeatability are important.

The MPL-B560F-MK72AA can be considered for rotary or auxiliary machine axes where its voltage, torque, speed and feedback characteristics match the requirements of the motion system.

Applications may include positioning mechanisms, rotary tables, tool-handling mechanisms and automated auxiliary axes.

---

7.3 Material Handling

Automated conveyors, transfer systems, indexing mechanisms and positioning units can benefit from servo-controlled motion.

Compared with a basic fixed-speed motor, a servo system can provide controlled acceleration, controlled deceleration, precise stopping and coordinated movement.

---

7.4 Printing and Converting Machinery

Printing and converting machines often require accurate synchronization between multiple rotating mechanisms.

Servo motors can control web handling, feeding, cutting, registration and synchronization functions.

The high-resolution feedback of the MPL-B560F-MK72AA is useful in applications where precise rotary coordination is required.

---

7.5 Assembly Automation

Automated assembly equipment often performs repetitive movements at high speed.

The motor’s low-inertia characteristics can help reduce the time required for acceleration and deceleration, particularly where the machine performs many repeated movements during each production cycle.

---

7.6 Semiconductor and Electronics Equipment

Precision manufacturing systems may require repeatable positioning and rapid response.

Servo motors with high-resolution feedback can be applied to automated stages, handling systems, indexing mechanisms and other controlled motion assemblies, provided that the environmental and precision requirements are satisfied.

---

7.7 Robotics and Automated Machinery

The MPL-B560F-MK72AA can also be considered for certain industrial robotic mechanisms and automated machinery.

The suitability depends on the required torque, inertia ratio, duty cycle, mechanical transmission, acceleration, speed and controller/drive compatibility.

---

8. Major Product Advantages

8.1 Fast Dynamic Response

The low-inertia rotor is one of the key benefits of the MPL series.

A low-inertia motor can respond quickly when the servo drive changes the commanded speed or position.

This can help reduce cycle time in machines that perform frequent acceleration and deceleration.

---

8.2 Accurate Motion Feedback

The multi-turn absolute encoder provides detailed feedback to the control system.

This makes the motor suitable for applications where accurate positioning and repeatable movement are more important than simply maintaining a constant rotational speed.

---

8.3 High-Speed Operation

With a rated speed of 3000 rpm, the motor can support relatively fast mechanical motion.

When combined with a suitable gearbox, belt drive, screw mechanism or other transmission, the motor can be adapted to a wide range of machine speed requirements.

---

8.4 Industrial Mechanical Design

The 165 mm frame and IEC metric mounting arrangement make the motor suitable for industrial machinery designed around standardized mechanical mounting concepts.

This can simplify integration into existing machine platforms when the original motor uses the same mechanical dimensions and mounting arrangement.

---

8.5 Flexible Cable Installation

The 180° rotatable right-angle connector can be valuable when space around the rear of the motor is limited.

This feature gives machine builders greater freedom when routing power and feedback cables.

---

8.6 No Unnecessary Brake

For applications that do not require a holding brake, the no-brake configuration can reduce unnecessary hardware.

It is particularly appropriate for horizontally mounted rotary axes or applications where the machine has another mechanism responsible for load holding.

---

9. Recommended Same-Series and Related Models

The following five models are useful comparison candidates when selecting a motor similar to the MPL-B560F-MK72AA. Some are from the same MPL family with different voltage, speed or stack configurations, while the related drive model is included because the servo motor must operate as part of a complete motion-control system.

Recommended Model	Series / Relationship	Voltage	Frame	Stack Length	Speed	Feedback	Brake	Weight	Dimensions
MPL-A560F-MK72AA	MP-Series MPL, same frame/stack configuration	230 V	165 mm	152.4 mm	3000 rpm	Absolute multi-turn, high resolution	No	Approx. 9.07 kg class	Frame 165 mm; stack 152.4 mm; overall length per drawing
MPL-B540K-MK72AA	MP-Series MPL, same voltage/frame family	460 V	165 mm	101.6 mm	4000 rpm	Absolute multi-turn, high resolution	No	Approx. 8–9 kg class	Frame 165 mm; stack 101.6 mm; overall length per drawing

MPL-B560F-MK72AA	MP-Series MPL, reference model	460 V	165 mm	152.4 mm	3000 rpm	Absolute multi-turn, high resolution	No	Approx. 9.07 kg	Frame 165 mm; stack 152.4 mm; overall length per drawing
2198-H025-ERS	Related Kinetix servo-drive platform	230/480 V-class system	Drive frame dependent	N/A	Application dependent	Drive feedback interface	N/A	Approx. 3 kg class	Compact cabinet-mounted drive; exact dimensions depend on configuration

Comparison Notes

The MPL-A560F-MK72AA is the closest electrical alternative when the machine requires a 230 V-class version while retaining the same 165 mm frame and 152.4 mm stack configuration.

The MPL-B540K-MK72AA is particularly interesting when higher rotational speed is more important than the longer 152.4 mm stack. Its 4000 rpm configuration provides a different performance balance from the 3000 rpm MPL-B560F-MK72AA.

The MPL-A540K-MK72AA provides a similar 4000 rpm configuration in the lower-voltage version.

The 2198-H025-ERS is not a direct motor replacement. It is included as a related motion-control component because servo motor selection should always be evaluated together with the servo drive, controller, feedback system and machine power architecture.

10. Five Popular Allen-Bradley Models for Related Applications

The following products are useful when expanding an automation system around the same general motion-control and industrial automation ecosystem.

11. MPL-B560F-MK72AA vs. MPL-A560F-MK72AA

The two models are mechanically very similar, but their electrical voltage configurations are different.

Parameter	MPL-B560F-MK72AA	MPL-A560F-MK72AA
Voltage Class	480 V class	240 V class
Armature Voltage	460 V	230 V
Frame	165 mm	165 mm
Stack	152.4 mm	152.4 mm
Speed	3000 rpm	3000 rpm
Feedback	Absolute multi-turn	Absolute multi-turn
Shaft	Keyless	Keyless
Brake	No	No
Connector	Right-angle SpeedTEC DIN	Right-angle SpeedTEC DIN
Weight	Approx. 9.07 kg	Approx. 9.07 kg class
Primary Difference	Higher-voltage configuration	Lower-voltage configuration

For a machine replacement project, the difference in voltage is critical. A 230 V motor should not be treated as a direct electrical replacement for a 460 V motor simply because the frame and mounting dimensions appear similar.

---

12. Why the MPL-B560F-MK72AA Is Suitable for Precision Automation

A servo motor is selected differently from an ordinary induction motor.

For a conventional motor, the primary concerns may be power, voltage, speed and environmental conditions.

For a servo motor, the selection process normally considers:

• Required continuous torque
• Peak torque
• Motor speed
• Load inertia
• Acceleration and deceleration
• Position accuracy
• Cycle time
• Duty cycle
• Mechanical transmission
• Encoder resolution
• Servo-drive compatibility
• Controller compatibility
• Cable requirements
• Environmental conditions
• Mounting arrangement
• Brake requirements

The MPL-B560F-MK72AA is attractive for applications where rapid dynamic response and precise feedback are important.

Its combination of a low-inertia rotor, 3000 rpm speed rating, high-resolution multi-turn feedback and 165 mm frame makes it a practical choice for medium-to-high performance industrial motion systems.

---

13. Installation and Selection Considerations

Before replacing an existing motor with the MPL-B560F-MK72AA, several parameters should be checked.

Electrical Compatibility

The servo drive must be suitable for the motor’s 460 V armature / 480 V-class configuration.

The drive’s continuous current and peak current capabilities must also be sufficient for the motor’s required operating point.

Mechanical Compatibility

The 165 mm frame size alone does not guarantee mechanical interchangeability.

The following should also be checked:

• Mounting flange
• Bolt-hole arrangement
• Shaft diameter
• Shaft length
• Shaft coupling
• Motor overall length
• Connector clearance
• Cable routing
• Load-side mechanical interface

Feedback Compatibility

The motor’s absolute multi-turn encoder must be supported by the selected servo drive and controller.

The feedback cable and connector arrangement should also be checked before installation.

Brake Requirements

This model does not include an integrated brake.

If the motor is installed on a vertical axis, inclined axis, lifting mechanism or any application where the load could move when motor power is removed, an appropriate holding solution should be evaluated.

Thermal Requirements

Motor heating depends on actual torque, speed, duty cycle, ambient temperature and installation conditions.

The motor should not be selected only according to the maximum nominal power value. The actual machine duty cycle should be considered.

---

14. Typical Machine Architecture

A typical application using this motor can be organized as follows:

Industrial Controller → Servo Drive → MPL-B560F-MK72AA Servo Motor → Mechanical Transmission → Machine Load

The encoder provides feedback from the motor to the servo drive.

The controller provides the motion command.

The servo drive regulates current and motor operation.

The motor converts electrical energy into controlled mechanical rotation.

The mechanical transmission then transfers the motor’s torque and speed to the machine mechanism.

This architecture allows the machine to perform highly repeatable movement rather than simply operating at a fixed motor speed.

---

16. Suitable Application Categories

The MPL-B560F-MK72AA can be considered for:

1. Automated packaging machines
2. High-speed indexing systems
3. Material handling equipment
4. Machine-tool auxiliary axes
5. Printing machinery
6. Labeling equipment

16. Electronic assembly machinery
17. Automated process equipment
18. General-purpose industrial servo applications

---

17. Recommended Selection Strategy

If the existing system already uses the MPL-B560F-MK72AA, the first choice for a replacement should normally be another motor with the same complete catalog number and compatible revision.

If the machine power architecture is different, the MPL-A560F-MK72AA may be considered where a 230 V-class motor is required.

If higher speed is needed and the mechanical load permits it, the MPL-B540K-MK72AA is a more speed-oriented alternative.

For applications where the motor itself is not the only concern, the servo drive should be selected at the same time. A servo motor and servo drive should be treated as a matched motion-control system rather than as independent components.

---

18. Overall Evaluation

The MPL-B560F-MK72AA is a robust industrial low-inertia servo motor intended for precision motion-control applications.

Its major characteristics are the 165 mm frame size, 152.4 mm magnetic stack, 3000 rpm rated speed, 460 V armature voltage, absolute multi-turn high-resolution feedback, keyless shaft, right-angle rotatable SpeedTEC DIN connector and no integrated brake.

Its strongest advantage is the combination of relatively fast response and precise feedback. This makes it more appropriate for demanding automated machinery than a conventional fixed-speed motor.

The motor is particularly well suited to equipment where short cycle times, repeatable positioning and controlled acceleration/deceleration are important.

For purchasing, replacement or engineering selection, the most important points to verify are the exact voltage configuration, servo-drive compatibility, required torque, load inertia, mechanical dimensions, shaft interface, feedback compatibility, cable arrangement and whether the application requires a holding brake.

Because the MPL-B560F-MK72AA has a specific mechanical configuration, its 165 mm frame size and 152.4 mm stack length should not be interpreted as the complete external envelope. For final cabinet or machine installation, the exact mechanical drawing should be used to verify the total motor length, shaft projection, flange dimensions, bolt pattern and connector clearance.
