---

6. Product Introduction

The MPL-B430P-MK74AA is designed for industrial automation systems in which the motor must respond quickly to changing motion commands.

A servo motor is not selected simply according to horsepower or kilowatt rating. The relationship between motor inertia, load inertia, acceleration requirements, operating speed, peak torque, continuous torque, and duty cycle is equally important.

The low-inertia design of the MPL family makes this motor especially useful for machinery that repeatedly accelerates, decelerates, stops, reverses, and repositions.

The motor’s 5000 rpm rated speed makes it suitable for high-cycle applications where machine productivity depends on fast axis movement.

At the same time, the approximately 6.55 N·m continuous torque provides substantial continuous mechanical output for its frame class.

During short-duration acceleration or transient load conditions, the approximately 19.8 N·m peak torque capability gives the servo system additional dynamic capacity.

This makes the MPL-B430P-MK74AA a practical choice for machines where both speed and controlled torque are important.

---

7. High-Speed 5000 rpm Performance

One of the major benefits of this motor is its 5000 rpm speed rating.

High rotational speed can be particularly useful in automated machinery where cycle time is a major factor.

Typical examples include:

• High-speed indexing
• Servo-driven conveyors
• Packaging mechanisms
• Material feeding
• Printing and converting equipment
• Rotary positioning
• Cutting mechanisms
• Automated assembly
• High-speed inspection systems
• Electronic synchronization systems

A higher motor speed can also allow a machine designer to use an appropriate mechanical transmission ratio to achieve the required load speed and torque.

The actual operating speed should always be selected according to the complete servo system, mechanical transmission, load characteristics, and drive configuration.

---

8. Torque Performance

The MPL-B430P-MK74AA provides approximately 6.55 N·m of continuous stall torque and approximately 19.8 N·m of peak torque.

Torque Parameter	Specification
Model	MPL-B430P-MK74AA
Continuous Stall Torque	Approx. 6.55 N·m
Peak Torque	Approx. 19.8 N·m
Continuous Power	Approx. 2.2 kW
Rated Speed	5000 rpm
Peak / Continuous Torque Ratio	Approx. 3:1

The difference between continuous and peak torque is important for servo applications.

Continuous torque relates to the motor’s ability to produce torque during sustained operation, while peak torque provides additional short-term capability for acceleration, deceleration, rapid positioning, and transient mechanical loads.

---

9. Absolute Multi-Turn Encoder

The MPL-B430P-MK74AA uses an absolute multi-turn high-resolution encoder.

Feedback Parameter	Specification
Model	MPL-B430P-MK74AA
Feedback Type	Absolute Multi-Turn
Resolution	Sin/Cos, 1024 cycles/revolution
Encoder Category	High Resolution
Feedback Protocol	Hiperface-type
Position Information	Absolute multi-turn position
Primary Function	Position, speed, and motion feedback

The absolute multi-turn configuration is valuable in applications where the control system needs reliable position information over multiple motor revolutions.

This can be especially useful for:

• Precision indexing
• Rotary positioning
• Electronic gearing
• Electronic camming
• Coordinated multi-axis motion
• Registration control
• Servo-driven feeding
• Automated assembly
• High-speed positioning systems

The feedback system also helps the servo controller maintain accurate control of speed and position during acceleration, deceleration, and load changes.

---

10. Keyless Shaft Configuration

The MPL-B430P-MK74AA uses a keyless shaft extension.

A keyless shaft can be advantageous when the mechanical system uses a compatible clamp-style coupling.

Compared with a keyed shaft arrangement, a keyless configuration can provide a clean mechanical interface and can be convenient for precision coupling and alignment.

When replacing an existing servo motor, however, the shaft configuration must be checked carefully. A motor with the same frame size and torque rating is not necessarily a direct mechanical replacement if the shaft, flange, shaft length, coupling, or mounting dimensions differ.

---

11. Integral 24 V DC Holding Brake

One of the most important differences between the MPL-B430P-MK74AA and several similar MPL configurations is the presence of an integral 24 V DC holding brake.

Brake Parameter	Specification
Model	MPL-B430P-MK74AA
Brake	Yes
Brake Type	24 V DC Holding Brake
Brake Voltage	24 V DC
Primary Purpose	Holding the motor/load when required
Typical Application	Vertical axes and holding applications
Control Requirement	Application-specific brake control

The integrated brake can be useful for applications where the motor needs to hold a position when servo torque is removed.

Typical applications include:

• Vertical lifting axes
• Z-axis positioning systems
• Elevating mechanisms
• Vertical assembly equipment
• Load-holding mechanisms
• Machine axes where controlled holding is required

The brake should be regarded primarily as a holding device, not as the normal operating method for repeatedly stopping a moving load.

The actual safety function, brake timing, load requirements, and vertical-axis protection strategy should be evaluated according to the complete machine design.

---

12. Connector Configuration

The motor uses a right-angle SpeedTEC DIN connector with approximately 180-degree rotational flexibility.

Connector Parameter	Specification
Model	MPL-B430P-MK74AA
Connector Type	SpeedTEC DIN
Connector Style	Right Angle
Connector Orientation	Rotatable
Rotation Range	Approximately 180°
Connection Advantage	Flexible cable routing
Installation Advantage	Reduced cable interference

This configuration is particularly useful in compact automation equipment.

When servo motors are installed close to machine frames, guards, gearboxes, conveyors, or other motors, cable routing can become a significant design problem.

The rotatable connector provides more freedom when determining the direction of the motor cable.

---

13. Mounting Configuration

The MPL-B430P-MK74AA uses IEC metric mounting and free mounting holes.

This makes the motor suitable for a wide range of industrial machine structures.

Mounting Parameter	Specification
Model	MPL-B430P-MK74AA
Mounting Type	Flange Mount
Mounting Standard	IEC Metric
Mounting Hole Configuration	Free Mounting Holes
Mounting Type Designation	Type FF
Frame Size	115 mm
Mechanical Class	Industrial Servo Motor

When installing the motor, sufficient clearance should be provided around the motor body and connector area.

Cable bending radius, connector access, brake wiring, motor temperature, and service access should all be considered during machine design.

---

Possible uses include:

• Auxiliary axes
• Indexing mechanisms
• Feed mechanisms
• Rotary positioning
• Automated tool positioning
• Auxiliary machine mechanisms

Final motor selection should be based on the actual torque, speed, acceleration, inertia, and duty-cycle requirements of the machine.

---

The integral 24 V DC brake makes this configuration particularly interesting for applications involving vertical movement.

Examples include:

• Vertical lifting systems
• Z-axis mechanisms
• Elevating platforms
• Vertical assembly stations
• Automated lifting mechanisms
• Load-positioning systems

The brake configuration can help provide a holding function when the servo system is not actively producing torque.

For safety-critical vertical applications, the motor brake should not automatically be considered the only protective measure. The complete machine safety architecture should determine the appropriate load-holding and emergency-stop strategy.

---

20. Important Engineering Considerations

Selecting a servo motor should always involve more than comparing the rated power.

The following parameters should be reviewed before final selection:

Load Torque

Determine the continuous torque required by the mechanical load.

The motor should have sufficient continuous torque for the actual duty cycle.

Acceleration Torque

Calculate the additional torque required to accelerate the motor and load.

High acceleration requirements can make the motor’s peak torque capability particularly important.

Load Inertia

The load inertia should be compared with the rotor inertia of the motor.

A suitable inertia relationship helps the servo system achieve stable and responsive control.

Maximum Speed

The application should be checked against the 5000 rpm motor speed rating.

The mechanical transmission ratio must also be considered.

Duty Cycle

Continuous, intermittent, repetitive, and peak-load operating conditions should be evaluated.

A motor that has enough peak torque may still be unsuitable if the load continuously demands more torque than the motor can dissipate thermally.

Vertical Loads

For vertical axes, the integral brake is an important advantage.

However, the complete mechanical and safety design should determine whether an additional load-holding or safety mechanism is necessary.

Coupling

Because the motor uses a keyless shaft, the selected coupling must be mechanically compatible with the shaft design.

Cable Routing

The right-angle, rotatable connector should be considered during machine layout.

Adequate space should be provided for the connector and cable bending radius.
