Overview
Core Technical Features
-
Direct Torque Control (DTC)
Equipped with ABB enhanced Direct Torque Control as standard. It delivers precise speed, torque and position control, supporting open‑loop (encoder‑less) and closed‑loop operation for induction motors, permanent‑magnet synchronous motors and reluctance motorseero. Built‑in motion functions allow axis synchronisation and positioning without external motion controllers; further customisation is available via IEC 61131‑3 PLCopen programmingeero.
-
Integrated Safety Functions
Safe Torque Off (STO) is factory‑standard. Optional extended safety functions support safe‑speed and safe‑stop requirements, lowering the need for external safety hardware. Coated circuit boards are applied as standard for improved performance in harsh industrial environmentseero.
-
Modular & Service‑friendly Design
Multiple frame sizes are available. Hot‑swap‑oriented module construction, removable memory units and quick‑connection accessories simplify commissioning, module replacement and on‑site maintenance. The typical maintenance interval reaches up to 9 years. All units undergo full‑load factory testing before deliveryABB Group.
-
Broad Connectivity
Multi‑slot control unit supports major fieldbus and industrial Ethernet protocols for seamless connection to PLC, HMI and higher‑level automation systems. Commissioning and tuning can be completed via the intuitive local control panel with USB port or ABB Drive Composer PC toolABB Group.
-
Energy‑saving DC‑bus Concept
Braking energy from decelerating drives can be directly reused by other inverters on the same DC‑bus. Regenerative supply modules feed surplus energy back to the utility grid. Total harmonic distortion can be kept low when applying active supply units, optimising grid qualityABB Group.
Main Benefits
- Lower capital and operating expenditure: shared power supply reduces component count, cabling work and overall cabinet footprinteero
- High power density for compact cabinet builds
- Unified software platform across all ACS880 drives, shortening engineering and training cycles
- Flexible braking solutions: energy sharing on DC‑bus may eliminate braking choppers in many cases
- Scalable system: add or remove inverter modules according to the number of controlled motor axes
