Description

Engineered for high-performance speed and torque control of AC induction and permanent magnet motors, the ACS355-03E-07A3-4 represents a highly versatile general machinery drive within the ABB ACS355 series. This compact variable frequency drive is optimized for cabinet installation, featuring an IP20 enclosure rating and integrated safe torque off (STO) functionality to enhance system safety and efficiency in automated production environments.

Operating with a three-phase input voltage range of 380 to 480 V AC, this drive delivers a continuous output current of 7.3 A and a nominal power output of 3 kW (3 HP). Its flexible control interface and support for multiple fieldbus protocols make it straightforward to integrate into existing industrial networks and automation architectures.

Features

Scalar and vector control modes for precise motor speed and torque regulation.
Integrated Safe Torque Off (STO) functional safety, certified to SIL3/PL e.
Built-in brake chopper as standard to handle regenerative energy during deceleration.
Uniform height and depth across frame sizes, enabling clean and space-efficient cabinet layouts.
FlashDrop compatibility for rapid, unpowered drive parameterization and commissioning.
High overload capacity to support heavy-duty machinery starts.

Applications

Conveyor and material handling systems
Packaging and labeling machinery
Food and beverage processing equipment
Mixers, agitators, and centrifuges
Industrial fans, pumps, and compressors

Installation Guidelines

Mounting: Designed for DIN-rail or direct screw mounting inside a clean, dry, and dust-free control cabinet.
Clearance: Ensure a minimum of 75 mm clearance above and below the unit, and 0 mm clearance on the sides to permit side-by-side mounting.
Grounding: Connect the protective earth (PE) terminal to the main cabinet ground bus using low-impedance cabling.
Shielding: Always use shielded motor cables to mitigate electromagnetic interference (EMI) and comply with local EMC regulations.
