The ABB ACS380‑040S‑01A8‑4 is a compact and reliable low‑voltage AC variable frequency drive (VFD) designed for control of three‑phase asynchronous and permanent‑magnet motors in industrial machinery. It belongs to the ACS380 family of machinery drives, which offer simple integration, adaptive programming, and excellent performance in a wide range of applications. The integrated control panel provides user‑friendly operation, and the drive supports essential functions such as sensorless vector control, PID control, adaptive programming, and safety features like Safe Torque Off (STO). This module is suitable for controlling motors with a rated power around 0.55 kW (0.75 HP) and rated current near 1.8 A on a 380–480 V AC three‑phase supply.
