ABB's low-voltage AC drives span five core families — ACS150, ACS355, ACS510, ACS580 and ACS880 — and the right choice depends on power, load type and control precision rather than brand. For pumps, fans and general centrifugal loads up to 160 kW, the ACS510 or ACS580 is the cost-effective default; for OEM machinery and constant-torque conveyors, the ACS355 or ACS580 fits; for cranes, extruders, hoists and any high-dynamic or regenerative duty, the ACS880 with Direct Torque Control is the only tier that meets the spec. Below is the full comparison and a five-step selection method.
ABB low-voltage variable frequency drives (VFDs, also called AC drives or inverters) control the speed and torque of three-phase AC motors from 0.37 kW up to several megawatts. They are organized in a tiered portfolio: micro/economy drives (ACS150), machinery drives (ACS355), general-purpose fan/pump drives (ACS510), all-compatible general-purpose drives (ACS580) and industrial drives (ACS880). All share ABB's "all-compatible" architecture and Drive Composer commissioning software, which simplifies spare parts and technician training.
Confirm power and supply voltage. Match the motor kW and line voltage: ACS150 covers 0.37–4 kW; ACS355 0.37–22 kW; ACS510 1.1–160 kW (380 V); ACS580 0.75–500 kW (up to 480 V); ACS880 0.55 kW–5600 kW (up to 690 V).
Classify the load. Variable-torque centrifugal loads (pumps, fans, blowers) point to ACS510/ACS580. Constant-torque machinery (conveyors, mixers, compressors) points to ACS355/ACS580. High-dynamic or lifting loads (cranes, hoists, extruders, winders) point to ACS880.
Pick the control method. Simple speed control only — ACS150 (scalar V/f). Need torque or PM-motor control — ACS355/ACS510/ACS580 (sensorless vector). Need torque response under 2 ms and full torque at zero speed — ACS880 (DTC).
List required functions. Built-in PID for pressure/flow loops (ACS510/ACS580); fieldbus flexibility and sequence programming (ACS355); regenerative braking and advanced safety SS1/SLS/SBC (ACS880 only); application macros for cranes/winders (ACS880).
Balance budget and commissioning. For straightforward, fast-deployment general duty, the ACS580 offers the lowest total installed cost with most features built in. For demanding, future-upgradeable process control, the ACS880 justifies its higher price through precision and scalability.
| Model | Positioning | Power range | Voltage | Control | Typical applications | Key features |
|---|---|---|---|---|---|---|
| ACS150 | Micro / economy | 0.37–4 kW | 200–240 V / 380–480 V | Scalar V/f | Small conveyors, fans, minor pumps, mixers | Built-in keypad & potentiometer, brake chopper, EMC filter, DIN rail |
| ACS355 | Machinery drive | 0.37–22 kW | 200–240 V / 380–480 V | Sensorless vector | Food & beverage, packaging, textile, woodworking, material handling | STO, sequence programming, fieldbus adapters, PM-motor capable |
| ACS510 | General purpose (fan/pump) | 1.1–160 kW | 3-phase 380 V | Scalar + PID | HVAC, constant-pressure water, cooling fans, tunnel ventilation | Built-in PID, swinging choke (harmonic mitigation), EMC filter, assistant panel |
| ACS580 | All-compatible general purpose | 0.75–500 kW | 3-phase 380–480 V | Sensorless vector + PID | Pumps, fans, compressors, conveyors, mixers (var. & const. torque) | Assistant panel, built-in EMC/chopper/Modbus/STO SIL3, swinging choke, all-in-one |
| ACS880 | Industrial drive | 0.55–5600 kW | 200–690 V | Direct Torque Control (DTC) | Cranes, hoists, winders, extruders, crushers, marine, metals, mining | DTC, removable memory, regenerative braking, advanced safety, application firmware |
Oversizing the tier. A 75 kW pump does not need an ACS880; an ACS580 covers it at lower cost. Reserve ACS880 for dynamic or regenerative duty.
Underestimating overload. Constant-torque loads need 150% overload for 60 s; confirm the drive's heavy-duty rating, not just nominal current.
Ignoring harmonics. Above about 75 kW or on weak grids, use the built-in swinging choke (ACS510/ACS580) or add an input reactor; verify IEEE 519 at system level.
Forgetting safety. If the application needs Safe Stop 1 or safely-limited speed, only the ACS880 supports it natively; ACS150/ACS355/ACS580 provide basic STO only.
The ACS580 uses sensorless vector control for stable, predictable loads, while the ACS880 uses Direct Torque Control (DTC) for torque response under 2 ms and full torque at zero speed. ACS880 also adds regenerative braking, advanced safety and crane/extruder firmware, covering 0.55 kW to 5600 kW versus 500 kW for the ACS580.
For HVAC, constant-pressure water supply and ventilation up to 160 kW, the ACS510 is purpose-built with PID and harmonic mitigation. The ACS580 extends the same applications to 500 kW and adds compressors and constant-torque loads.
Yes. The ACS355 uses sensorless vector control and can run both standard induction and permanent-magnet (PM) motors, which is why it is popular with OEMs in packaging, textile and material-handling machinery.
The ACS580 covers 0.75–500 kW at 380–480 V, available in wall-mounted (-01), module (-04) and cabinet (-07) configurations. For higher power or 690 V, move to the ACS880 platform.
The ACS355, ACS580 and ACS880 include Safe Torque Off (STO) certified to SIL 3 / PL e as standard. The ACS150 offers basic protection but not full STO; advanced functions (SS1, SLS, SBC) are native only on the ACS880.
Use the ACS880 with crane-control application firmware and DTC. It delivers precise low-speed torque, load sharing and regenerative energy return, which standard vector drives cannot match safely.
