ACS180-04S-02A6-4 Variable Frequency Drive ACS180 0.7 kW 3x380

ACS180-04S-02A6-4 is a 0.7 kW ABB drive, three-phase 3×380 V supply, 2.6 A rated current. A basic three-phase model for small serial machines: small pumps, fans, dosers, low-power conveyor belts. It is the smallest three-phase frame in the series, so by current and size it fits neatly into dense cabinets next to other ACS180 units.

Typical applications:

• Small pump or fan on a 380 V three-phase mains
• Dosing or packaging unit
• Drive for a small conveyor

Note: when sizing, match against the 2.6 A motor current — the motor must not be larger than the drive. Scalar and sensorless vector control (induction and PM motors), embedded Modbus RTU. The brake chopper and EMC filtering depend on the frame variant — for strict requirements confirm the exact part number.

ABB ACS180 — compact machinery drive for serial-built machines

The ACS180 is ABB's entry-level machinery VFD covering 0.25–22 kW. Its job is straightforward: give OEMs and integrators a reliable compact drive without extra options, but with what a machine actually needs — sensorless vector control, embedded Modbus RTU and a built-in Safe Torque Off (STO) safety function. It is effectively the modern replacement for the older ABB ACS150 and ACS355 in the lower machinery class. If you want a "mount it in the cabinet and it runs" drive for a pump, fan or conveyor, this is a workhorse.

Where the ACS180 fits

• Pumps and fans: built-in energy optimization lowers motor flux at partial load — less current, quieter operation. Typically 0.7–22 kW.
• Conveyors: sensorless vector control holds torque at low speed; larger frame sizes include a built-in brake chopper for controlled stops.
• Compressors, mixers, winders: ABB lists mixing and winding machines among the series applications.
• Single-phase supply: the "1" variants run from a 1-phase 230 V mains and deliver a 3-phase output — handy where only a single domestic phase is available but the motor is three-phase (up to 3 kW).

How the ACS180 compares

Honestly: on motor control the ACS180 and budget Veichi drives in this class are close. You pay for the ABB name, embedded SIL3-rated STO, long support and service. If the machine is simple and the budget is tight, Veichi AC10/AC01 will cover the same job for less.

When the ACS180 is NOT the right choice

• You need closed-loop encoder feedback, high dynamics, or PROFINET/EtherCAT — go to ABB ACS380/ACS580 or a drive with a PG card. The ACS180 is sensorless and Modbus-RTU-centric.
• Power above 22 kW — out of the series range; see larger drives.
• A very simple single machine on a tight budget — consider Veichi AC10/AC01.

Our experience with the ACS180

In practice the ACS180 is bought exactly for serial machines and typical engineering jobs — pump, ventilation, conveyor. Two questions come up most often. First, single-phase input: yes, the "1" models run from 230 V one phase and drive a three-phase motor up to 3 kW. Second, braking: the built-in chopper is present from frame size R2 upward, so for the smallest enclosures confirm it for your specific case. EMC filtering also depends on the variant — if you have strict electromagnetic-compatibility requirements, agree on the exact part number before ordering. We will help you match the model to your mains and motor.
