WATER DRIVES WATER DRIVES

General software features Built-in pump application software

The built-in pump application software in the ACQ580 drives is designed to enhance the
reliability and durability of the water and wastewater application in which it is used. The
functions protect the pump and secure its optimal functionality, increasing cost efficiency.
The built-in functionalities also support the user in securing the flow of the water and
wastewater in the pump solution.

out of the box, according to their needs. This is complemented by Multi-pump functionality Quick-ramp
