AC Drive

Rockwell Automation introduced its Allen-Bradley PowerFlex 527, the company’s first AC drive designed to work exclusively with a Logix-based programmable automation controller (PAC) and uses a single software package – Rockwell Software Studio 5000 Logix Designer. The drive uses a standard EtherNet/IP infrastructure and features built-in, dual-port EtherNet/IP functionality. The drive also enables networked safety, which helps reduce the hardware, wiring and labor costs associated with implementing a SIL 3/PLe safety solution.

Networked safety also allows access to more diagnostic data on machine safety faults and causes, without requiring contactors or relays. The drive also offers an embedded, safe torque off function option for hardwired safety. The PowerFlex 527 is available in five frame sizes, power ratings from 0.4 to 22 kW (0.5 to 30 Hp), and global voltage ratings of 100 to 600V.
