MPL-A210E-V-X246 Low-Inertia Servo Motor — Detailed Specifications, Product Introduction, Applications, Advantages and Related Models

1. Product Overview

The MPL-A210E-V-X246 is a low-inertia servo motor configuration used with an integrated ballscrew linear-stage system.

It belongs to the MPL low-inertia servo motor series within the MP-Series motion-control product family and is specifically configured for a 200 V-class, 5 mm/rev ballscrew linear stage without an integrated brake.

The model is associated with the MPAS integrated linear-stage configuration MPAS-Axxxx1-V05S2A. In this arrangement, the servo motor provides the rotary motion while the ballscrew converts that rotary motion into controlled linear travel.

This is an important distinction because the MPL-A210E-V-X246 is not simply a general-purpose rotary servo motor. Its catalog configuration is intended for a particular linear-motion application, making the complete catalog number important when selecting a replacement.

---

2. Brand and Product Series

The most important identifying characteristics are 200 V class, 5 mm/rev ballscrew, and no brake.

3. Main Technical Parameters

4. Product Identification

The MPL-A210E-V-X246 belongs to a group of special MPL configurations intended for integrated linear stages.

The final X246 designation is particularly significant because it identifies the specific motor configuration rather than merely identifying a general MPL motor.

For this configuration, the associated mechanical arrangement uses a 5 mm/rev ballscrew.

The corresponding brake-equipped configuration is MPL-A210E-V-X247.

The 400 V versions are MPL-B210E-V-X248 and MPL-B210E-V-X249, while the 200 V, 20 mm/rev versions are MPL-A220H-V-X250 and MPL-A220H-V-X251.

This makes the X246 part of a fairly clear configuration family:

This configuration relationship is useful when selecting a replacement because a visually similar motor can still have a different electrical or mechanical configuration.

---

5. What the MPL-A210E-V-X246 Does

The MPL-A210E-V-X246 is used to create controlled linear movement through a ballscrew.

The basic operating principle is:

Motion Controller → Servo Drive → Servo Motor → Ballscrew → Linear Stage → Machine Load

The motion controller determines where the axis should move.

The servo drive controls the electrical power supplied to the motor.

The motor rotates the ballscrew.

The ballscrew converts rotary motion into linear movement.

The linear stage then moves the machine component, fixture, tool, product or workpiece attached to the stage.

This arrangement provides considerably more control than a simple motor running continuously at a fixed speed.

The machine can command specific positions, velocities and acceleration profiles according to the production sequence.

---

6. 5 mm/rev Ballscrew

The 5 mm/rev ballscrew pitch is one of the most important characteristics of the X246 configuration.

In basic mechanical terms, one revolution of the ballscrew corresponds to approximately 5 mm of linear travel.

For example:

The actual machine movement depends on the complete servo system, feedback, control parameters and mechanical configuration.

A 5 mm/rev pitch is useful when the machine requires relatively controlled linear movement rather than very large travel per motor revolution.

---

7. Brake Configuration

The MPL-A210E-V-X246 does not have an integrated motor brake.

This is an important selection point.

A holding brake is normally used when the machine needs the motor to hold its position after servo power is removed.

The X246 does not provide this function through an integrated motor brake.

The closely related MPL-A210E-V-X247 provides the brake-equipped configuration.

For a horizontal axis, a brake may not be necessary depending on the machine design.

For a vertical axis or an axis carrying a suspended load, brake requirements need to be considered carefully.

---

8. Low-Inertia Motor Design

The MPL series is designed around low-inertia brushless servo motor technology.

Low rotor inertia is valuable in applications where the motor needs to change speed frequently.

For example, an automated machine may perform the following sequence:

Accelerate → Move → Decelerate → Stop → Reverse → Accelerate → Stop

Every change in speed requires the servo system to control the motor’s rotational inertia.

A lower-inertia motor can make these changes more responsive.

This characteristic is particularly useful in:

• High-cycle automation.
• Repetitive positioning.
• Pick-and-place machinery.
• Packaging systems.
• Assembly machines.
• Inspection equipment.
• Multi-axis automation.

The actual dynamic performance depends on the complete motor, drive, load, ballscrew and servo-tuning combination.

---

9. Product Introduction

The MPL-A210E-V-X246 is designed for applications where a servo motor and ballscrew linear stage work together as a precision motion axis.

Instead of producing useful work through a rotating shaft alone, the motor drives a mechanical transmission that generates linear displacement.

This arrangement is well suited to machines where the position of a component needs to be controlled electronically.

The servo system can command the axis to move to different positions without requiring mechanical stops or fixed mechanical indexing mechanisms for every movement.

For production machinery, this provides considerable flexibility.

The same linear axis can be programmed to move different distances, use different speeds and follow different acceleration profiles depending on the machine recipe or operating condition.

---

10. Main Advantages

10.1 Precision Linear Movement

The ballscrew mechanism provides controlled linear movement.

The 5 mm/rev configuration is useful where the machine requires a relatively fine mechanical pitch.

---

10.2 Low-Inertia Servo Response

The low-inertia motor design supports rapid changes in motor speed.

This is particularly useful in machines with frequent acceleration and deceleration.

---

10.3 Programmable Motion

Unlike a simple fixed-speed motor, the servo system can control:

• Position.
• Speed.
• Acceleration.
• Deceleration.
• Direction.
• Motion sequence.

This allows the same axis to perform multiple programmed movements.

---

10.4 200 V-Class Configuration

The X246 belongs to the 200 V-class linear-stage motor configurations.

This provides a clear distinction from the related 400 V versions.

The voltage class must match the servo-drive and machine architecture.

---

10.5 Non-Brake Configuration

The absence of an integrated brake can be useful where a brake is unnecessary.

This is particularly applicable to certain horizontal linear-motion applications.

---

10.6 Integrated Linear-Stage Compatibility

The motor is intended for the corresponding MPAS integrated linear-stage configuration.

This is useful for machine builders because the motor and mechanical transmission are part of a defined linear-motion solution.

---

10.7 Repetitive Motion Capability

The servo-driven stage can repeatedly execute programmed movements.

This makes the configuration suitable for automated manufacturing equipment where the same movement is repeated hundreds, thousands or even millions of times during machine operation.

---

11. Typical Applications

Automated Assembly

The X246 can be used for positioning components, tooling and fixtures during automated assembly.

Typical operations include:

• Component insertion.
• Part positioning.
• Tool movement.
• Fixture adjustment.
• Press positioning.
• Alignment.

The servo controller can coordinate the linear axis with other machine movements.

---

Inspection Equipment

Inspection systems often require cameras, probes or sensors to move along a defined path.

A servo-driven linear stage can provide controlled movement for:

• Camera positioning.
• Sensor scanning.
• Probe movement.
• Workpiece positioning.
• Measurement sequences.

---

Packaging Machinery

Servo-driven linear axes are commonly useful in packaging equipment.

Possible functions include:

• Product indexing.
• Feeding.
• Positioning.
• Cutting.
• Sealing.
• Forming.
• Product alignment.

The programmable motion profile allows the machine to adapt movement to different products and production speeds.

---

Electronics Manufacturing

The motor and linear stage can be used in equipment requiring controlled movement of components, tooling or inspection devices.

Potential applications include:

• PCB positioning.
• Component handling.
• Automated inspection.

The system can also be used for controlled movement of machine components and workpieces.

Typical examples include:

• Transfer mechanisms.
• Linear pushers.
• Positioning tables.
• Stop mechanisms.
• Automated slides.
• Workpiece alignment.

---

Machine Automation

The X246 can serve as one linear axis within a larger automation system.

It can be coordinated with:

• Rotary servo motors.
• Additional linear axes.
• Conveyors.
• Robotic systems.
• Vision systems.
• PLC-controlled machinery.

This makes it suitable for multi-axis automated equipment.

---

12. Five Closely Related Models

The following five models are especially relevant to the MPL-A210E-V-X246 because they belong to the same linear-stage motor configuration group.

These five models are useful comparisons because they change either the voltage class, brake configuration or ballscrew pitch while remaining closely related to the X246 configuration.

---

13. Detailed Comparison of Related Models

---

14. Five Same-Brand Representative Models

For a broader comparison, the following are representative models from the same brand and MPL motion-control range.

These models are representative of the broader MPL servo-motor range rather than direct substitutes for the X246.

The X246 is a special linear-stage motor configuration, so a conventional rotary MPL motor should not be treated as a drop-in replacement simply because it belongs to the same MPL family.

---

15. X246 Compared With X247

The X246 and X247 are the closest pair in this product group.

If the existing machine requires a holding brake, the X247 configuration is the relevant version to evaluate.

If the existing machine was designed without a motor brake, the X246 configuration maintains the original non-brake arrangement.

---

16. X246 Compared With X248

The X248 changes the voltage class.

Although the two configurations use the same basic 5 mm/rev mechanical concept, their electrical system requirements are different.

Therefore, the X248 should not be substituted for X246 without confirming the servo-drive and electrical architecture.

---

17. X246 Compared With X250

The X250 changes the ballscrew pitch.

The theoretical travel per revolution of the 20 mm/rev configuration is four times that of the 5 mm/rev configuration.

This does not automatically make one configuration better than another.

The appropriate choice depends on the required linear speed, positioning requirements, load, acceleration and mechanical design.

---

18. Dimensions and Weight

The MPL-A210E-V-X246 is a motor configuration associated with an MPAS linear stage rather than a complete linear-stage catalog number containing a fixed stroke.

Because MPAS stages can use different stage sizes and stroke configurations, it is not appropriate to assign one universal overall length, width and height to every X246 application.

The same issue applies to weight.

The motor catalog number alone should not be used to infer the total weight of the complete linear-stage assembly.

For this reason, the engineering-level physical information is presented as follows:

For purchasing or replacement work, the safest method is to match the complete motor catalog number and the existing stage configuration instead of estimating physical dimensions from the model number alone.

---

19. MPAS Stage Stroke

The MPAS linear-stage family can be configured with different stroke lengths.

Examples of available stroke coding include:

Not every stroke is necessarily available with every stage frame configuration.

The important point is that the motor X246 itself does not determine the complete length of the linear stage.

The stage frame and selected stroke have to be considered together.

---

20. Servo Control Structure

A typical motion system using the MPL-A210E-V-X246 can be arranged as follows:

PLC / Motion Controller

↓

Motion Network

↓

Servo Drive

↓

MPL-A210E-V-X246

↓

Ballscrew

↓

MPAS Linear Stage

↓

Machine Load

The controller sends the motion command.

The servo drive controls the motor.

The motor rotates the ballscrew.

The ballscrew generates linear movement.

Feedback is used by the servo system to maintain the commanded motion.

This type of architecture is especially useful for machines requiring repeatable, programmable movement.

---

21. Applications Where the X246 Configuration Makes Sense

The X246 configuration is particularly appropriate when the machine requires:

• Controlled linear positioning.
• Repeated linear movements.
• Programmable motion profiles.
• Servo synchronization.
• Rapid acceleration and deceleration.
• Accurate positioning.
• Compact linear-axis construction.
• Ballscrew-based motion.
• Integration with a multi-axis servo system.

It is less appropriate to think of the X246 as a simple replacement for any generic motor.

Its mechanical application is tied to the appropriate linear-stage arrangement.

---

22. Practical Advantages in Machine Design

A servo-driven linear stage provides several practical advantages for automation engineers.

Programmable Position

The axis can move to different positions according to software commands.

Programmable Speed

Different sections of the movement can use different velocities.

Controlled Acceleration

The machine can use controlled acceleration and deceleration rather than abrupt mechanical movement.

Repeatability

The same movement sequence can be repeated during production.

Multi-Axis Synchronization

The linear axis can operate together with other servo axes.

Recipe-Based Operation

Different products can use different motion parameters without requiring major mechanical changes.

Compact Integration

The motor and linear-stage system can be integrated into a relatively compact machine axis.

---

23. Maintenance Considerations

When maintaining an MPL-A210E-V-X246 system, the motor should not be considered separately from the linear stage.

Important inspection points include:

A positioning error does not necessarily mean that the motor itself has failed.

The problem can also originate from the ballscrew, bearings, coupling, feedback system, cables, servo tuning or an unexpected change in machine load.

---

24. Replacement Selection Checklist

Before replacing an MPL-A210E-V-X246, verify the following:

---

25. Important Difference Between Motor Weight and Stage Weight

This point is worth emphasizing.

A motor catalog number such as MPL-A210E-V-X246 identifies the motor configuration.

The complete MPAS linear stage can include:

• Motor.
• Ballscrew.
• Linear bearings.
• Stage carriage.
• Stage frame.
• Coupling.
• Cable management.
• Covers or seals.

Because of this, the weight of the complete linear-stage assembly is not necessarily the same as the weight of the motor.

For procurement and mechanical design, the complete assembly weight should be confirmed from the exact stage configuration.

Therefore, it would be inaccurate to insert an arbitrary kilogram value simply to fill the table.

29. Final Product Description

The MPL-A210E-V-X246 is a specialized MPL low-inertia servo motor configuration for an MPAS integrated ballscrew linear stage.

Its key configuration is 200 V class, 5 mm/rev ballscrew, and no integrated brake.

The motor converts electrical servo commands into controlled rotary motion, while the ballscrew converts that rotation into linear travel. This makes the complete system suitable for precision positioning, automated assembly, inspection, packaging, material handling and other industrial motion applications.

The 5 mm/rev pitch provides a relatively fine mechanical transmission compared with 10 mm/rev or 20 mm/rev configurations. This can be useful when the machine needs controlled linear movement and a relatively fine mechanical pitch.

The absence of an integrated brake is another defining characteristic. When a holding brake is required, the closely related MPL-A210E-V-X247 configuration should be considered instead.

The 400 V alternatives are represented by MPL-B210E-V-X248 and MPL-B210E-V-X249, while the 200 V / 20 mm-rev configurations are represented by MPL-A220H-V-X250 and MPL-A220H-V-X251.

For replacement work, the most important points are the complete catalog number, voltage class, ballscrew pitch, brake configuration, feedback arrangement, servo-drive compatibility, mechanical mounting and the exact MPAS stage configuration.

The dimensions and weight should be treated as configuration-dependent rather than assigning an unsupported fixed value. This is especially important because the overall physical dimensions and weight of an MPAS linear-stage assembly depend on the selected stage size and stroke.

In short, the MPL-A210E-V-X246 is best suited to applications that need a 200 V-class, non-brake, 5 mm/rev servo-driven linear stage with repeatable and programmable motion.
