FAQs
The ACS355-03E-04A7-2 is a low-voltage drive designed to connect to LV mains and drive both AC induction and permanent magnet motors. Plan for the 0.75 kW output and 4.7 A current, connect control and safety wiring according to the device’s wiring diagram, and enable built-in Safe Torque Off. Use the included sequence programming to minimize external controllers and simplify integration with your existing PLC or control logic.
Key specifications include a 0.75 kW nominal power rating and a 4.7 A current rating, with capability to control speed and torque for AC induction and permanent magnet motors. The unit features Safe Torque Off for safety and supports sequence programming. Verify voltage compatibility, motor type, and control I/O requirements to ensure optimal dynamic response and process stability.
Yes. The ACS355-03E-04A7-2 is well-suited for material handling and packaging due to its precise speed/torque control, built-in safety features, and easy integration with LV networks. It supports conveyors, lifts, and multi-motor configurations, enabling smooth start-ups, accurate positioning, and reduced risk when coordinating multiple drives in a line.
ABB’s ACS355 family typically aligns with CE conformity and incorporates safety features like Safe Torque Off to support compliant control architectures. Specific certification details (SIL, IP ratings) can vary by market and configuration, so confirm local regulatory requirements and model variants with your ABB distributor or technical representative.
The ACS355-03E-04A7-2 reduces hardware complexity with built-in safety and programming features, which lowers commissioning time and panel space.
