Typical applications

The ACS310 drive is specifically designed to meet the variable

torque loads demanded by centrifugal fans and pumps. The

result is maximum application uptime, reduced maintenance

cost and higher energy savings.

Irrigation systems, whether agricultural, horticultural or those

used on golf courses, have a common demand for a reliable

and efficient flow of water.

The built-in real-time clock provides true time and date stamps

that control the start and stop times of watering based on the

daily demand profile. Soft pipe filling provides a pump with

soft-start, enabling a smooth build-up of flow in pipes while

increasing the life time of the pipe work and pumping system.

A booster pump system is designed to boost supplied water

pressure to a predetermined level in water and wastewater

plants. The ACS310 drive features pump and fan control (PFC)

for use where several parallel pumps are operated together and

the required flow rate is variable.

PID control is available to allow the process to accurately

maintain a pressure setpoint by adjusting the control outputs,

thus allowing for precise control within difficult processes.

A sleep & boost function detects slow rotation and runs the

pump to boost pressure prior to shutdown. The pressure

is continuously monitored and pumping restarts when the

pressure falls below the minimum level.

Level control is used to adjust the filling or emptying of storage

tanks. Storage tanks may be located within processes such as

pulp and paper for supplying process fluids like wastewater.

The drive has signal supervision for level control and a pipe

cleaning feature, thereby preventing solids from building up on

pumps impellers or the tank walls.

Storage tanks are often mounted in narrow locations, with

limited space for components like AC drives. The compact size

and various mounting methods of the ACS310 drives enables

easy installation and space savings in new installations and

retrofits.

Wood drying kilns have a high demand for powerful and

efficient ventilation to dry out the wood. In wood kilns

centrifugal fans and AC drives are used to control the air flow

demand. To increase the kilns´ capacity, multiple fans may be

controlled via one drive by using the pump and fan control

(PFC) feature. At the start of the drying process, the relative

humidity is high thus there is a demand for higher air flow

rates. As the wood dries out the auxiliary fans may shut-down,

thereby saving energy and reducing maintenance.
