ABB ACS380-040S-12A6-4 Industrial AC Drive

The ABB ACS380-040S-12A6-4 is a next-generation compact drive from the ACS380 series, designed for machinery applications that demand robust performance, ease of use, and compliance with global safety standards. It serves as a direct replacement for the ACS355 series with enhanced features.

Electrical Ratings

• Input voltage: 380–480 V AC, 3-phase, 50/60 Hz

• Rated current (I_N): 12.6 A (heavy-duty), 10.5 A (normal duty)

• Motor power: 7.5 HP (5.5 kW) at 460V

• Output frequency: 0–500 Hz

• Overload capacity: 150% for 60 seconds (heavy-duty)

• Frame size: R0 (IP20 / UL open type)

Control and Performance

The drive features direct torque control (DTC) as standard, providing superior torque regulation and speed accuracy (±0.5% without encoder). The built-in vector control algorithm optimizes motor efficiency. It supports both induction motors and permanent magnet motors (PM).

Safety and Compliance

Integrated STO (Safe Torque Off) function complies with SIL 3 (IEC 61508) and PL e (ISO 13849-1). The drive also includes an optional Safe Stop 1 (SS1) by external safety relay. It meets CE, UL, cUL, and EAC markings.

Communication

Standard onboard Modbus RTU (RS-485) and a second Modbus/TCP via optional fieldbus adapter. Available fieldbus modules: PROFINET, EtherNet/IP, PROFIBUS DP, DeviceNet, CANopen.

User Interface and Programming

The drive includes a basic control panel with LED status indicators; an optional assistant control panel with multimonitor display is available. Parameter setting is assisted by the Drive composer PC tool, supporting start-up wizards and oscilloscope functions.

Applications

Ideal for conveyors, mixers, extruders, centrifuges, cranes, and food processing equipment. The ACS380 series is specially designed to meet the demands of harsh environments with coated boards and vibration resistance up to 5g.

Energy Efficiency

Class IE2 efficiency per IEC 61800-9, with energy optimizing function that reduces losses by up to 20% compared to standard PWM drives.

Dimensions and Installation

Width 70mm, height 202mm, depth 169mm; weight 1.6kg. Mounts on 35mm DIN rail or via screws. Operating temperature -10°C to 50°C (derate above 40°C).

Conclusion

The ABB ACS380-040S-12A6-4 combines modern motor control technologies with a compact, safe, and energy-efficient design, making it an excellent choice for OEMs and machine builders.
