The ABB ACS355-03E-07A3-4 is a compact 3.0 kW variable frequency drive for three-phase 380 to 480 VAC motor systems. With a rated output current of 7.3 A, it is suitable for machinery that requires adjustable motor speed, controlled acceleration, and repeatable operating cycles.
This R1-frame ACS355 drive is designed for compact machine cabinets and standalone motor-control sections. It is commonly used where a standard AC motor must run at different speeds according to process demand, production sequence, material flow, or machine cycle timing.
The ACS355-03E-07A3-4 supports scalar control and sensorless vector control for compatible motors. Its Safe Torque Off function supports machine safety design when correctly integrated into the control circuit.
This product is a single-motor variable frequency drive. It should not be described as a servo amplifier, motion controller, PLC, or multi-axis drive system.
