The ABB ACS355-03E-04A1-4 is a compact 1.5 kW (2 HP) three-phase machinery drive designed for general industrial automation applications. With a rated output current of 4.1A and input voltage range of 380–480V AC, this IP20 panel-mount VFD delivers output frequencies from 0 to 600 Hz using advanced vector control (both V/f and sensorless vector). The drive features 6 programmable digital inputs, 2 analog inputs, 2 relay outputs, and built-in RS485 Modbus RTU communication with optional fieldbus expansion (Profinet, Modbus, CANopen, DeviceNet, EtherNet/IP). Safety is ensured by integrated STO (Safe Torque Off) SIL3 function. Compact dimensions of 239 × 70 × 187 mm and CE, cUL, C-Tick certifications make it ideal for food processing, material handling, textile, and packaging machinery applications requiring precise speed control in limited cabinet space.
Q: What motor types can the ACS355-03E-04A1-4 control?
A: It is designed for standard AC induction motors with vector control and V/f scalar control modes.
Q: What is the maximum output frequency?
A: The drive supports output frequencies from 0 to 600 Hz.
Q: Can this drive be used for pump and fan applications?
A: Yes. The ACS355 includes application macros for pump/fan control with built-in PID regulation for constant pressure or flow applications.
Q: Does it support fieldbus communication?
A: Built-in RS485 Modbus RTU is standard. Optional fieldbus adapters are available for Profinet, CANopen, DeviceNet, and EtherNet/IP.
Q: What safety features are included?
A: The drive includes STO (Safe Torque Off) rated SIL3 / PL e, meeting the highest machinery safety standards.
