ABB ACQ580-01-018A-4 Water Drive 7.5 kW 17 A

7.5 kW pump drive on frame R2

Municipal and industrial pump stations that need a 7.5 kW drive for a 380 to 480 V supply can use the ACQ580-01-018A-4. It delivers 17 A nominal from a frame R2 housing and combines an EMC filter, a DC choke, Safe Torque Off and Modbus RTU in the basic unit. It opens frame R2 at 7.5 kW and fits mid-size transfer and booster sets.

Typical functions in the ACQ580 pump control program are resonance monitoring, real-time clock scheduling, soft pipe filling to avoid pressure peaks and quick ramps that reduce wear on submersible pumps. Other ratings sit in AC drives, with the series description on the ABB ACQ580 page.

Technical specifications

Light and heavy duty on 17 A

Pick the duty by load: 16.2 A / 7.5 kW suits centrifugal pumps, with 110% for 60 seconds (about 17.8 A, derived). Positive-displacement or sludge pumps with high breakaway torque may need the heavy-duty column, 12.6 A / 5.5 kW, which permits 150% for a minute (about 18.9 A, derived). The 2-second start limit is 22.7 A, and nominal use is 17 A.

Input fuses are 40 A type 170M1563 to IEC and 30 A type JJS-30 to UL. The drive dissipates about 240 W, moves 101 m3/h of air and is rated at no more than 64 dBA at full fan speed; detailed fuse sizes are in the hardware manual 3AXD50000044862.

Dimensions for frame R2: IP21 473 x 125 x 229 mm at 6.6 kg; IP55 503 x 128 x 239 mm at 6.8 kg (heights include the gland box). With a main switch or C1 filter fitted, ABB lists the IP55 body at 503 x 128 x 257 mm and 7.5 kg.

Motor pairing: the catalogue’s SynRM selection guide matches this drive with 7.5 kW M3AL132SMB4 at 3000 rpm (16.5 A nominal, motor efficiency 93.1%, package efficiency 90.4%); 7.5 kW M3AL132SMB4 at 1500 rpm (15.7 A nominal, motor efficiency 93.7%, package efficiency 91%); 7.5 kW M3BL160MLA4 at 1000 rpm (16.5 A nominal, motor efficiency 93.1%, package efficiency 90.2%). Efficiency numbers describe that combination only and are calculated by ABB.

Type code and option codes

ACQ580-01-018A-4 breaks down as ACQ580 (series), 01 (wall-mounted), 018A (rating) and 4 (380 to 480 V). The standard panel is the Hand-Off-Auto ACH-AP-H. Typical extras are +L501 for CMOD-01 (24 V and relay), +L512 for CHDI-01 (115/230 V inputs), +L523 for CMOD-02 (isolated PTC) and +L525 for CAIO-01 (3 AI, 2 AO).

Communication: Modbus RTU is built in. For plant networks, ABB’s table gives PROFIBUS DP FPBA-01 (+K454, 68469325), CANopen FCAN-01 (+K457, 68469376) and Modbus RTU FSCA-01 (+K458, 3AUA0000031336). The fieldbus module sits in slot one and I/O extensions in slot two.

Across the family the catalogue specifies Safe Torque Off to SIL 3 / PL e, EMC class C2 as standard for ACQ580-01, a C1 option up to 55 kW, a built-in DC or AC choke meeting IEC 61000-3-12 and 6 digital inputs, 2 analog inputs, 2 analog outputs and 3 relays.
