ABB ACH580-01-05A7-4 HVAC AC Drive 2.2 kW 5.6 A

2.2 kW HVAC drive on frame R1

Building services engineers who need a 2.2 kW drive on a 400 V supply will find the ACH580-01-05A7-4 in ABB’s ACH580 catalogue. The type delivers 5.6 A nominal output from a frame R1 housing and ships with the HVAC control program, an assistant control panel, a DC choke and Safe Torque Off. It is the 2.2 kW step on frame R1, often chosen for small circulation pumps and fan coils.

Software separates it from a general purpose drive: the HVAC program supplies real-time clock scheduling, PID controllers for process control, motor flying start and motor preheating. Browse neighbouring ratings in AC drives or read the general ABB ACS580 overview for the sister platform.

Technical specifications

Sizing the ACH580-01-05A7-4 against the motor

Match the drive to the motor nameplate current. At 400 V the light-duty figure is 5.3 A (2.2 kW) and the nominal figure 5.6 A; the catalogue allows a 110% overload for one minute every ten minutes, roughly 5.8 A (derived from the 110% rule). Under a 480 V supply the table shows 4.8 A and 3 hp. The ratings are specified at +40 degrees C.

Allow 125 mm of width and 223 mm of depth for the IP21 drive, plus a height of 373 mm with the gland box. The IP55 enclosure needs 128 mm by 233 mm and 403 mm in height and weighs 4.8 kg, against 4.6 kg for IP21. With a main switch or C1 filter variant the IP55 body becomes 403 x 128 x 255 mm and 5.4 kg.

Motor pairing from the catalogue: the ACH580-01-05A7-4 is listed with 2.2 kW M3AL90LA4 at 3000 rpm (5.6 A nominal, motor efficiency 85.9%, package efficiency 83.8%) in the IE4 synchronous reluctance (SynRM) selection guide. The efficiency figures are ABB’s calculated drive-plus-motor values and do not promise the same result with a different motor.

Type code and option codes

The designation breaks down as series ACH580, construction 01 (wall-mounted), size 05A7 and voltage code 4 for 380 to 480 V. ABB lists these additions, among others: +L501 for the CMOD-01 relay and 24 V module, +L523 for CMOD-02 with an isolated PTC interface, +L512 for CHDI-01 with 115/230 V inputs and +B056 for IP55.

Add a fieldbus only when the building network needs one: CANopen via FCAN-01 (+K457), LonWorks via FLON-01 (+K452) and ControlNet via FCNA-01 (+K462) are among the choices.

Across the range ABB specifies an operating range of -15 to +50 degrees C, 5 to 95% relative humidity without condensation, altitude derating of 1% per 100 m between 1000 and 4000 m, coated circuit boards and a DC choke built to IEC 61000-3-12.

Typical HVAC applications for this rating

Small drives of this size are widely used in building services where pumps and fans rarely need full speed for most of the day. Chilled water and heating circulation pumps, fan coil units, small air handling unit fans, toilet and kitchen extract fans and booster pumps are common examples. Running these loads through a drive allows the speed to follow actual demand instead of throttling flow with dampers or valves, which reduces energy use and noise and gives smoother operation of the system.

The HVAC control program supports this directly. The PID controllers allow the drive to hold a pressure, temperature or flow setpoint from a sensor signal, the real-time clock scheduling allows occupancy-based operation without an external timer, flying start lets the drive catch a fan that is already windmilling, and motor preheating helps keep the motor dry during standstill.

Selection considerations

Sizing starts with the motor nameplate current at the actual supply voltage, as described above, rather than with motor power alone. The load type matters too: centrifugal pumps and fans are variable-torque loads that suit the light-duty rating, while other loads may need a different approach. Check the site temperature and altitude against the stated operating range and derating rules, and choose the enclosure class according to where the drive will be mounted. IP21 suits clean electrical rooms, while the IP55 option is intended for plant rooms or locations with more dust and moisture.

Integration with building management systems

Many buildings connect drives to a building management system so that start, stop, speed reference and status can be handled centrally. The fieldbus choices listed above allow the drive to join the network already used in the building, while the option modules provide additional relay outputs, PTC motor protection or higher-voltage digital inputs where the control scheme requires them. Safe Torque Off provides a hardwired way to prevent the motor from producing torque, which can be used within the safety concept of the installation.

Agreeing the control method early, whether hardwired signals, fieldbus or local PID control, avoids rework during commissioning and helps the integrator prepare the correct points list.

Installation in Oman and GCC buildings

Plant rooms on rooftops and in basements across the region can become hot and humid, especially in summer. Because the ratings are given at a defined ambient temperature, mount the drive where the temperature stays within the published limits, with clear space around it for cooling air as described in the ABB installation manual. Where plant rooms are dusty or exposed to moisture, the IP55 version is the safer choice. Coated circuit boards add protection against humidity, but condensation should still be avoided.

Follow the ABB manual for cable selection, earthing and motor cable routing, and keep motor and control cables separated to reduce interference with sensors and building network signals.
