Yaskawa servo drives are commonly used equipment in the field of industrial automation. The following will introduce their working principles, advantages and features, common models and application fields:
Working Principle
Control Core: Using a Digital Signal Processor (DSP) as the control core, it can implement relatively complex control algorithms, thus achieving digital, networked, and intelligent control.
Power Drive Unit: The input three-phase power is rectified through a rectifier circuit to obtain the corresponding direct current. Then, the three-phase sinusoidal PWM voltage-type inverter is used to convert the frequency to drive the three-phase permanent magnet synchronous AC servo motor, that is, the AC-DC-AC process.
Control Modes: Three control modes, namely position control, speed control, and torque control, are adopted. These control modes enable the servo drive to accurately control the rotation of the motor, thereby achieving high-precision positioning. It also controls the output by collecting feedback signals to achieve a more precise control effect.
Advantages and Features
High Performance and High Precision: It can provide high-precision control, with small torque fluctuations and low speed regulation rates, ensuring the stability and accuracy of movement. For example, the torque accuracy of the Σ-X series has been improved to ±5%, the encoder resolution has been increased to 26 bits, and the response frequency has reached 3.5 kHz.
Intelligent Sensing and Predictive Maintenance: The new generation of the Σ-X series incorporates the i³-Mechatronics concept and has a predictive maintenance function. It can monitor the equipment status in real time, predict potential failures through data collection and analysis, and reduce downtime.
Strong Adaptability: It is designed with a wide range of inertia adaptation. For example, the Σ-X series supports up to 100 times load variation compensation, enabling the system to maintain stable operation under different loads.
Easy Debugging: It provides enhanced debugging functions, including visual debugging results, which simplifies the system configuration and parameter adjustment process. Even complex mechanisms can be easily handled.
Wide Application Support: It is widely used in multiple industries, from robots, automation systems, and CNC machine tools to wind farms. It performs particularly well in scenarios that require high-precision positioning and rapid response.
Common Models
Σ-X Series: As an iterative product of the Σ-7 series, while improving the motion performance, it better incorporates the i³-Mechatronics concept, supports the flexible use of data sensing functions. The torque accuracy has been improved to ±5%, the encoder resolution has been increased to 26 bits, the response frequency has reached 3.5 kHz, and it supports up to 100 times load variation compensation.
SGD7S Series: It is characterized by high responsiveness and high precision, with a relatively high speed response frequency. It is suitable for various occasions that require high-precision control. Models such as SGD7S-180A00B202 can be matched with a variety of Yaskawa servo motors and are widely used in industrial automation production lines, robots, and other fields.
SGDV Series: For example, models such as SGDV-5RA501A002000 and SGDV-5R5A11A have multiple control functions and protection circuits, which can achieve precise control of servo motors and are commonly used in automation equipment, CNC machine tools, and other equipment.

It covers four functional models, including ethercat, ethernet, built-in mci210, and flexible base servo drives. The torque range is 0.7 nm – 51 nm (peak 153 nm), the current range is 1.5 a – 16 a (peak 48 a), the power range is 0.25 kw – 7.5 kw. It supports mainstream bus protocols and is compatible with a variety of encoders.

Robot Field: It provides robots with fast response, high precision, and stable performance control, enabling robots to achieve various complex movements and operate stably in high-speed, high-load, and other environments. It is widely used in various industrial robots such as welding robots, handling robots, and assembly robots.
Automation Systems: It can meet the needs of various automation systems, from intelligent logistics to automated production lines, providing precise and fast control functions, and improving production efficiency and product quality.
CNC Machine Tools: It can accurately control the various actions of CNC machine tools. Its high-precision position control and fast response performance are the keys to achieving precision machining. It can improve the accuracy and production efficiency of CNC machine tools and is widely used in fields such as mold manufacturing and aerospace component processing.
Other Fields: It is also applied in industries such as textiles, printing and packaging, and wind farms. For example, it can achieve high-precision unwinding, rewinding control, and tension control on textile winding machines; accurately control the rotation speed and position of printing cylinders in printing and packaging machinery, and achieve accurate sealing and labeling of packaging bags; efficiently control wind turbines in wind farms to ensure their stable operation in various environments.
