Why ACQ580 is used in pumping systems
The ABB ACQ580-01-02A7-4+B056 belongs to ABB's water and wastewater drive family. ACQ580 drives are intended for pump and motor control tasks where operators need stable flow, controlled pressure, simplified commissioning, and energy-aware operation. Typical project contexts include water intake, booster stations, treatment processes, wastewater transfer, irrigation, and utility pumping.
Application-oriented ACQ580 functions
- Sensorless flow calculation for estimating pump flow without a separate flow meter in suitable applications.
- Multi-pump control for systems that coordinate more than one pump.
- Level control for tank, sump, and process-water applications.
- Soft pipe filling to help reduce pressure shocks during system startup.
- Dry-run protection and pump-cleaning functions for operating continuity.
- Energy-saving calculation for reviewing drive-controlled pump operation.
Availability and configuration of individual functions should be confirmed against the installed firmware, application program, accessories, and ABB documentation for the delivered unit.
What +B056 changes in the order code
For ABB ACQ580-01-02A7-4+B056, +B056 is not a separate drive model; it is an enclosure option within the complete ABB type designation. ABB documentation defines +B056 as IP55 (UL Type 12). Buyers should retain the suffix in quotations and purchase orders because an ACQ580-01-02A7-4 without +B056 may have a different enclosure specification.
Replacement and procurement checks
- Send a clear nameplate photo and keep every character of ACQ580-01-02A7-4+B056 in the RFQ.
- Confirm the 400 V supply class, motor current, motor power, duty profile, and required overload capability.
- State whether the unit is for a new panel, a wall-mounted installation, or replacement of an existing drive.
- List required fieldbus adapters, I/O extensions, control-panel options, disconnects, filters, or other plus codes separately.
- Provide quantity, destination country, required delivery date, and any documentation or packing requirements.
When comparing ABB ACQ580-01-02A7-4+B056 with a nearby ACQ580 rating, verify the full current code and option suffix instead of assuming that similar enclosure dimensions indicate identical electrical ratings. HKXY can use the complete order code, nameplate information, and application notes to prepare a model-specific quotation.
Frequently asked questions
What is the rated output of ACQ580-01-02A7-4+B056?
