AC Servo Drive Σ-X

Industry’s best motion performance

・The speed response frequency, which is an important evaluation index for servo drives, has reached 3.5 kHz as the world’s highest level, by improving the ability to follow commands and ensuring stable operation, resulting to improve productivity. The maximum speed of the servomotor reaches 7000 rotations per min, increasing the driving speed of the device, shortening the tact-time and improving productivity. Equipped with an encoder with a resolution from conventional 24 bit (16 million Pulse/Rotation) to the industry’s highest level of 26 bit (67 million Pulse/Rotation), it improves stop accuracy and realizes smoother movement.

By improving the servo adjustment function required to maximize the device performance such as high speed and high precision, it has become possible to easily perform optimum and stable servo adjustment in a short time, including mechanisms that were previously difficult to adjust.

Digital data solutions starting with servo

・For preventive maintenance of the equipment and improvement of production quality, it is important to take various data from an equipment, and a servo becomes a sensor by the data detection function which is strengthened from “Σ-7 Series”. ・With the Σ-LINK II sensor network, the encoder signal line can be connected to various sensors, I/O devices, and other devices installed on the machine side. The use of wire-saving and high-speed sensor data synchronized with the encoder enables the system to achieve higher functionality and performance. ・In order to detect equipment abnormalities in advance, Σ-X has various sensing functions as well as environmental and lifetime monitoring. Σ-X can detect abnormalities by monitoring changes in the device.
