In the world of industrial automation, precision, reliability, and speed are paramount. At the heart of many high-performance machines lies a critical component: the servo drive.
Product Overview
The YASKAWA SGDV-R90A11B is a member of the versatile Σ-V series servo system. Designed as a MECHATROLINK-II communication command-type drive, it serves as the intelligent intermediary between a control system and a servo motor. Its primary role is to precisely control motor torque, speed, and position, making it an indispensable component in complex automated machinery.
Core Specifications and Data
Understanding the hard data is key to evaluating any industrial component. The SGDV-R90A11B is built for robust performance within clear electrical and physical parameters.
Power Ratings: This drive belongs to the "R90" power class. It operates on a three-phase 200-230V AC main power supply. Its rated continuous output current is 0.91 Amps (RMS), with a capability to deliver up to 2.9 Amps (RMS) for instantaneous peak torque demands.
Key Features: It is designed as a MECHATROLINK-II communication command-type unit, enabling high-speed, synchronized multi-axis control through a single network.
Environmental Robustness: The drive is built for challenging industrial environments. It is rated for operation in temperatures ranging from 0 to 40°C and relative humidity between 20% and 80% (non-condensing). This ensures stable operation in most factory conditions.
Key Technical Features and Advantages
The SGDV-R90A11B distinguishes itself through a suite of features designed for performance, ease of use, and integration.
High-Speed, Synchronized Control: Utilizing the MECHATROLINK-II field network, this drive enables real-time communication with a transmission speed of up to 10 Mbps. A single network can connect and synchronously control up to 30 stations, drastically simplifying system wiring and architecture compared to traditional pulse-train control.
Versatile Control Modes: It offers integrated control over torque, speed, and position. These modes can be switched online via parameters, allowing for smooth and effective execution of complex mechanical movements without needing multiple specialized drives.
Enhanced Precision and Smoothness: The drive is engineered to work seamlessly with high-resolution serial encoders (commonly 17-bit to 22-bit), which provide extremely accurate motor position feedback for precise positioning. Features like advanced vibration suppression and friction compensation functions help achieve smooth rotation and stable positioning, even at low speeds or with fluctuating loads.
Design for Maintainability: It incorporates user-friendly design aspects for easier setup and maintenance. The main and control circuit power supplies are completely separated; in an alarm state, only the main power needs to be shut off for troubleshooting. A built-in parameter setting unit also allows for direct configuration on the drive itself.
Typical Application Scenarios
The reliability and precision of the SGDV-R90A11B make it a preferred choice across various high-tech and demanding manufacturing sectors.
Semiconductor and Electronics Manufacturing: This is a primary application area. The drive is commonly found in semiconductor manufacturing equipment, chip mounters (pick-and-place machines), and printed circuit board (PCB) drilling machines, where micron-level precision and high throughput are critical.
Industrial Automation and Robotics: It provides the precise motion control required for industrial robots, automated handling machinery, and components of conveyor systems.
Machine Tool and General Industry: The drive is also suitable for machine tools requiring precise feed control, as well as various other automated machines in packaging, food processing, and inspection/testing equipment.
The YASKAWA SGDV-R90A11B is more than just a power amplifier for a motor. It represents a sophisticated control nexus that combines robust electrical specifications, a high-speed digital communication interface, and intelligent control algorithms. By delivering synchronized multi-axis control, exceptional precision, and operational reliability, it empowers machinery in semiconductor fabrication, advanced robotics, and automated manufacturing to achieve higher levels of performance and productivity. For engineers designing systems where motion is mission-critical, the SGDV-R90A11B remains a compelling and trusted solution.
