AC drives promises 'just enough' control

16 October 2013

Adding to its Allen-Bradley PowerFlex 520-series of compact AC drives, Rockwell Automation has introduced the PowerFlex 523 AC drive, with flexible features designed to help users be more competitive.

Suited to builders of simple, stand-alone machines, the PowerFlex 523 AC drive balances user needs for 'just enough' control, with a design that lowers the total cost to design, develop and deliver machines.

Commenting on the features of the new drive, Jimmy Koh, global marketing manager at Rockwell Automation said: "Stand-alone machine builders wanted 'just enough' motor control and emphatically shared the need for features that ease configuration and speed installation. This is where their profitability was most affected, and we designed the PowerFlex 523 drive to meet those needs."

To make configuration easier, machine builders can use a standard USB connection for uploading and downloading drive-configuration files. They also can program the drive through its built-in human interface module (HIM), which displays data on the drive’s LCD with scrolling QuickView text and detailed explanations of parameters and other codes. The HIM has multiple language options.

Unique to the PowerFlex 520-Series AC drives, AppView and CustomView tools help speed up configuration by providing groups of parameters for common applications and by allowing users to save their settings to new parameter groups. These tools can be easily accessible via the HIM, as well as configuration software tools.

For more sophisticated networked requirements, machine builders can take advantage of an optional dual-port EtherNet/IP adapter for the PowerFlex 523 AC drive. This supports ring topologies and provides device level ring functionality, which can help provide network resiliency and drive machine availability.

The modular design of the PowerFlex 523 AC drive gives machine builders greater installation flexibility. Removing the drive's control module from its power module further reduces startup time, as machine builders can complete configuration and installation simultaneously.
