Frequently Asked Questions
1. What is the purpose of the servo system?
A servo system is designed to deliver high-precision control over position, speed, and torque in motion control applications. Used widely in industrial automation, servo systems ensure that machinery operates with exact movements. In the case of the Mitsubishi servo system, advanced servo motors and high-speed servo amplifiers offer seamless integration with factory automation, supporting everything from robotic arms to high-speed packaging lines.
2. Servo Motors vs. Servo Amplifiers
A servo motor generates controlled motion, while a servo amplifier (or drive) powers and regulates the motor using feedback from sensors. Together, they form the core of any servo system. Mitsubishi’s servo range, such as the MR-J5 series, offers advanced amplifiers that work in sync with high-resolution motors to deliver fast, responsive, and accurate control for complex automation tasks.
3. What is the main difference between a standard motor and a servo?
Unlike standard motors that run at a fixed speed, servo motors are built for precision and feedback-driven control. A servo system constantly adjusts the motor’s position and speed based on real-time data. With Mitsubishi servo motors, this capability is taken further using built-in encoders and intelligent servo amplifiers for ultra-precise industrial motion control.
4. How long do servo drives last?
Most servo amplifiers, including those from Mitsubishi Electric, have a typical lifespan of 10–20 years, depending on the operating environment and maintenance. Mitsubishi’s servo drives are known for their reliability and durability in demanding industrial conditions, especially when paired with compatible automation equipment like MELSEC PLCs.
5. How powerful is a servo motor?
Servo motors come in a variety of power ratings, from compact 50W models to high-powered industrial units delivering tens of kilowatts. Mitsubishi servo motors offer scalable power options suitable for lightweight pick-and-place systems up to heavy-duty machine tools and gantries, all while maintaining exceptional speed and control.
6. Why is it called servo?
The term “servo” comes from the Latin servus, meaning “to serve,” reflecting how these systems automatically adjust to reach a desired output. A servo system continuously monitors feedback and corrects its movements—precisely what Mitsubishi’s servo solutions are designed to do in modern factory automation.
7. What would you use a servo for?
Servo systems are used wherever precise motion control is required—such as in robotics, conveyors, CNC machines, and assembly lines. Mitsubishi servo motors are especially popular in industries like electronics, automotive, food & beverage, and packaging, where speed and precision are mission-critical.
8. What is the advantage of servo?
The key advantage of a servo system is its ability to offer high-speed, high-accuracy motion control with real-time responsiveness. Mitsubishi servo systems go further with features like absolute positioning, vibration suppression, and easy integration with their PLCs and HMIs—making them ideal for smart factories and Industry 4.0 setups.
9. What are the disadvantages of a servo?
While servo motors and drives offer incredible performance, they can be more expensive than basic motor systems and may require careful setup and tuning. However, Mitsubishi’s servo range simplifies commissioning with auto-tuning features and easy-to-use software tools—helping reduce engineering time and increase ROI.

Understanding Servo Systems
A servo system is much more than a basic motor—it’s an intelligent, feedback-driven control loop that brings machines to life with precise and dynamic movement. By combining Mitsubishi servo motors, servo amplifiers, and high-resolution encoders, these systems regulate motion with exceptional responsiveness.
Used in electric motors, automation lines, packaging machines, and robotics, servo systems deliver consistent results across a wide variety of industries. Whether you’re in food & beverage, pharmaceutical manufacturing, materials handling, or automotive assembly, Mitsubishi servos ensure efficiency and precision.
Definition and Components
A complete servo system includes a type of motor (like AC servo motors, DC servo motors, or Brushless Servo Motors), a servo amplifier, feedback devices such as Absolute encoders, and a motor controller. Mitsubishi’s MELSERVO platform integrates these seamlessly.
Key Functions and Applications
Servos perform critical functions like:
- Torque and speed control
- Accurate position feedback and speed feedback
- Smooth linear motion or rotary actuation through a drive shaft or output shaft
Applications span industrial servomotors, Integrated servomotors, robotics, and Linear Servo Motors, with Mitsubishi’s solutions trusted in Modern servomotors and automation setups.
Servo Motor Fundamentals
Mitsubishi servo motors offer dynamic response, high torque output, and low electrical noise, making them ideal for high-speed, high-precision applications. With built-in control circuitry and robust software control options, these motors are built to handle rigorous power requirements.
How Servo Motors Work
A servo motor receives a control input from a controller and adjusts its position using encoder data. This creates a closed-loop control system that dynamically adjusts power and feedback.
Differences Between Servo Motors and Stepper Motors
Stepper motors are a common type used in basic systems, but lack position feedback. Closed-loop stepper motors and closed loop stepper systems try to bridge this gap, yet Brushless DC and Brushless Servo Motors remain superior in terms of maximum torque, responsiveness, and safe torque delivery.
Common Applications of Servo Motors
Typical applications include:
- CNC machines in metal fabrication
- Robotic pick-and-place in electronics assembly
- High-speed labeling in packaging
- Conveyor tracking in logistics
- Precision dosing and filling in pharmaceuticals
- Automated palletizing in food and beverage production
Servo Amplifier Basics
Servo amplifiers regulate power between the controller and the motor. Mitsubishi’s MELSERVO-J4 series delivers high-resolution response and built-in digital drives.
Function and Importance of Servo Amplifiers
Amplifiers adjust current to match load demands and power source quality. They connect directly to the connector to power and factor in current consumption, avoiding spikes in consumption under max load.
Differences Between Servo Drives and Servo Amplifiers
Though terms often overlap, analog servo drives refer to legacy systems. Newer Tuning Free Servo Motors and Tuning Free Servo Motor Drivers simplify setup and offer better output torque tuning.
Applications of Servo Amplifiers
- Robotics and automated gantries
- Servo-controlled tools in branch of power electronics
- Integration with dedicated servo drivers, servo controller units, and controller circuits
Feedback Mechanisms in Servo Systems
Accurate motion relies on encoder feedback. Mitsubishi motors include Absolute encoders, high-end encoder types, and support torque limit settings based on system loads.
Role of Encoders
Encoders measure motor shaft rotation, reporting back via control signal wires. High-end systems even adjust torque output in real time.
Importance of Precise Control and Positioning
Thanks to position at power, systems hold their place during startup. This ensures accuracy, especially in environments with electrical noise or fluctuating power supply.
Integration with Microcontrollers
While industrial setups use PLCs, basic demonstration setups may integrate simple servos with Arduino or Raspberry Pi to simulate servo behaviors. These help illustrate the inherent benefits of Mitsubishi’s industrial-grade servos.
Using Servos with Arduino
Prototype systems may test movement logic and control options using control input and voltage regulators, but real-world deployment relies on robust systems from Venus Automation.
