For machine builders and compact panels, ABB's small-frame drives cover the ground below the 580 platform: the ACS380 machinery drive with integrated safety and fieldbus for OEM machines, the ACS480 and ACS180 for general small-power applications, and the ACH480 and ACQ80 variants tuned for HVAC and water duty.
The ACS380 machinery drive replaced the ACS355 for OEM machine applications, and the ACS480/ACS580 range covers what the ACS310 and ACS355 served in general-purpose duty. Sizing is straightforward, but mounting and terminals differ — send the old type code for an exact quote.
Many compact drives ship without an assistant control panel, which is ordered separately or shared across drives during commissioning.
