Product Description

The Keyence SV-020L2 is a compact and high-performance AC servo amplifier designed for precise motion control in industrial automation applications. It supports both three-phase and single-phase AC input (200–230 V) and is capable of driving a 200 W servo motor. The amplifier utilizes a three-phase full-wave rectification method with IGBT and PWM control, providing sine-wave current driving for smooth and efficient motor operation. With a continuous output current of 1.6 Arms and a peak of 5.8 Arms, it ensures reliable performance under varying load conditions. The SV-020L2 features a built-in regenerative resistor, control circuit power loss of 17 W, and total power loss of 30.5 W, contributing to its energy efficiency. It also includes safety functions such as STO (Safe Torque Off) with a response time of 8 ms, meeting international safety standards like SIL3 and PLe. The amplifier offers versatile I/O options, including 8 input channels and 4 output channels, supporting various control signals. Additionally, it supports MECHATROLINK-II communication for seamless integration into motion control systems. With its robust design and comprehensive features, the SV-020L2 is ideal for applications requiring precise and reliable servo control.
