Motors and Drives
include, among others, integrated PID and PFC (pump and fan control) controllers that alter drive performance based on pressure, flow or other external changes, and protection features such as pump cleaning. This prevents pumps and pipes from becoming blocked, starting a pumping sequence forwards and backwards, the settings of which vary depending on the application requirements.
assembly options of ACS310 drive enable easy installation and best use of space in new or renovated facilities.

● In fan applications the drive regulates the airflow for energy savings in industrial, retail and household environments.
● In a pressure control pump system the pump and fan control (PFC) macro of the ACS310 drive is useful when various pumps are operated in parallel mode at the same time and the flow required is variable.
● Irrigation systems all need a reliable and efficient water flow. The integrated real-time timer displays actual date and time to regulate start-up and stopping of the irrigation system based on daily demand. Even filling of pipes helps ensure a soft start-up of the pump, thus enabling a progressive flow increase in the pipes. This also extends the life span of the pumping network and system.
● In the filling and emptying of storage tanks ACS310 has a gauge to control and monitor level regulation. The useful pipe cleaning feature prevents the formation of solid deposits in the pump impellers or tank walls. Storage tanks are often located in tight spaces. So the compact size and various
The ABB machinery drive ACS355 meets a broad spectrum of requirements of machinery applications. Compact and uniform, with a fast start-up due to the application macros and the assistant panel. Features include an integrated braking chopper and
an integrated serial Safe Torque Off (SIL3). Both ideal for applications in the industrial food and beverage, material handling, lifting systems, textiles, printing and processing of rubber, plastic and wood. Some examples of use:

● Packaging machines often require a drive for repetition and precision during packaging. The ACS355 is ideal for packaging tasks providing optimum precision for static and dynamic speed regulation. Sequence programming enables the drive to perform task sequences, which reduce the need for a PLC. Software features include a timer, meter, brake control and slow operating, all of which are useful for packaging machines.
● It also comes with high protection (IP66). This range has been designed for applications exposed to dust, moisture and cleaning chemicals such as cylinders, mixers, pumps, fans and conveyor belts. ●
