ABB ACH580-01-04A1-4 HVAC AC Drive 1.5 kW 4 A

Where the ACH580-01-04A1-4 fits in a building

At 1.5 kW it is one of the smallest drives on the R1 frame and suits small air handling fans. The catalogue type that matches is the ACH580-01-04A1-4: three-phase, 1.5 kW typical motor power, 4 A nominal current, frame R1. It is the HVAC-optimised sibling of ABB’s general purpose drive and keeps the same all-compatible platform, so panels, PC tools and fieldbus adapters carry over.

Functions that building automation asks for come with the drive, for example override (fire) mode, four start interlocks, belt-loss (under-load) detection and real-time clock scheduling. Other sizes are listed in AC drives, and the related general-purpose family is on the ABB ACS580 drive page.

Technical specifications

Duty ratings of the ACH580-01-04A1-4

Voltage changes the answer. A 380 to 415 V network gives 1.5 kW and 4 A nominal, 3.8 A light duty. A 440 to 480 V network gives 3.5 A light duty for 2 hp. Because HVAC loads are variable torque, light duty usually applies, with about 4.2 A (110%, derived) available for a minute. Ratings are for +40 degrees C.

Mounting data for frame R1: the standard IP21 unit is 125 mm wide and 223 mm deep, 373 mm high with the gland box or 331 mm without, and weighs 4.6 kg. Order the IP55 variant and the body grows to 403 x 128 x 233 mm and 4.8 kg. With a main switch or C1 filter variant the IP55 body becomes 403 x 128 x 255 mm and 5.4 kg.

For energy-efficiency work, ABB’s IE4 SynRM motor table lists the ACH580-01-04A1-4 alongside 1.5 kW M3AL90L4 at 3000 rpm (3.9 A nominal, motor efficiency 84.2%, package efficiency 82.1%); 1.5 kW M3AL90LB4 at 1500 rpm (3.8 A nominal, motor efficiency 82.8%, package efficiency 80.7%). These numbers describe that specific pairing; ABB calculates them for the combined drive and motor, and other motor types need their own check.

Type code and option codes

Read ACH580-01-04A1-4 in four parts: ACH580 is the series, 01 the wall-mounted construction, 04A1 the rating and 4 the 380 to 480 V class. Plus codes from the catalogue then add features, for example +F278 for a main disconnect switch with auxiliary contact, +F316 for the disconnect switch plus a C1 filter, +C135 for flange mounting and +L501 for the CMOD-01 relay and 24 V module.

BACnet MS/TP, Modbus RTU and N2 need no adapter. Other networks plug in as F-series adapters, such as PROFINET IO via FPNO-21 (+K492), EtherNet/IP via FEIP-21 (+K490) and PROFIBUS DP via FPBA-01 (+K454).

Standard equipment and limits listed by ABB: six digital inputs and two analog inputs, two analog outputs and three relay outputs, a 24 V DC auxiliary supply of 250 mA, thermistor inputs for PTC and Pt100, Pt1000, KTY or Ni1000 sensors and an operating range of -15 to +50 degrees C.

Selection guidance for small HVAC fans and pumps

Start the selection from the motor nameplate rather than from the kilowatt figure alone. The drive must be able to supply the rated motor current in the duty that applies, so compare the nameplate current with the light-duty and nominal currents in the table at the actual supply voltage. If the motor current sits close to the limit, or the drive will run in a hot plant room, look at the next rating up, the ACH580-01-05A7-4, before deciding. Then choose the enclosure: IP21 suits a clean electrical or plant room, while the IP55 variant is the usual choice where the drive is mounted close to the fan or pump in a dusty or damp space. Finally, decide whether a main disconnect switch, a C1 filter or a fieldbus adapter is needed, and add the corresponding plus codes to the type designation.

Integration with the building automation system

Because BACnet MS/TP, Modbus RTU and N2 are available without an adapter, many building automation systems can talk to the ACH580-01-04A1-4 directly over a serial link, which keeps the panel simple. Where the site uses PROFINET, EtherNet/IP or PROFIBUS, the F-series adapters named above are the route. Agree with the controls contractor which signals are exchanged over the network and which stay hard-wired, especially for safety-related functions such as the fire override and the start interlocks.

Installation and commissioning considerations

Mount the drive within the ambient limits stated above, with clearance for cooling air, and follow the ABB hardware manual for cabling, earthing and the screening of motor cables. During commissioning, enter the motor nameplate data, check the direction of rotation, and set the speed limits and ramps to suit the fan or pump. Test the override mode, start interlocks and belt-loss detection before handover so that the building operator knows they work as intended.

How to specify your RFQ

Send the full type designation with any plus codes, the quantity and the delivery point, together with the motor nameplate data, the supply voltage, the enclosure class and the communication protocol. If the drive replaces an existing unit, a photo of its rating plate lets us confirm the match before we quote.

Documents and quotation

Request the ACH580-01-04A1-4 from Seven Star LLC with your motor nameplate, supply voltage and communication needs; the quotation gives availability and lead time. Ratings, dimensions, motor pairing and option codes on this page were taken from ABB catalogue 3AUA0000186691, revision F (9.14.2019), available via the document link.

Confirm before ordering: type code and plus options, motor rated current, enclosure class, ambient temperature and altitude, and any change in newer ABB documents.
