YASKAWA ∑ - V series AC servo drive

YASKAWA ∑ - V series AC servo drive

Core positioning

The YASKAWA ∑ - V series AC servo drive focuses on the entire lifecycle of design, testing, adjustment, and maintenance. It is compatible with SGDV series servo amplifiers and SGMMV/SGMJV/SGMAV rotary servo motors, as well as SGMCV/SGMCS direct drive servo motors. Its core applications include high-frequency, high-speed, and high-precision positioning scenarios (such as automated production lines, precision machine tools, robots, etc.), and it also specifies compliance requirements and safety operating standards such as UL in North America, CE in the European Union, and UKCA.
