AC Drives

Rockwell Automation introduced the Allen-Bradley PowerFlex 523 AC drive, which allows machine builders to use a USB connection to transfer drive-configuration files or program the drive through its built-in human interface module (HIM). In addition, the PowerFlex 520-Series’ AppView and CustomView tools provide groups of parameters for common applications and by allowing users to save their settings to new parameter groups. Builders can also use an optional dual-port EtherNet/IP adapter that supports ring topologies and provides device level ring (DLR) functionality. The drive has a power range of 0.25 hp (0.2 kW) to 15 hp (11 kW) and motor-control options, including volts per hertz, sensorless vector control and Economizer mode in sensorless vector control.
