PowerFlex 527 AC Drive Specifications
Product Overview
PowerFlex® 527 AC drives are designed to be used with an Allen-Bradley® Logix Programmable Automation Controller
(PAC). Ideal for machines that can benefit from the same drive configuration experience for both servo and AC drives, the
PowerFlex 527 drive features a built-in dual port for EtherNet/IP™ and safety over the network. The PowerFlex 527 drive
provides maximum flexibility and performance ranging up to 30 HP and 22 kW.
Designed to connect and operate only with the ControlLogix® 1756-L7x, GuardLogix® 1756-L7xS, and CompactLogix™
5370 controllers and Studio 5000 Logix Designer™ application. The PowerFlex 527 is programmed with the embedded
motion instructions within Studio 5000, these are the same instructions that are used for Allen-Bradley Kinetix® servo
drives. This streamlined approach provides a common user experience and just one software package to learn and use. The
commonality and use of consolidated integration tools helps save valuable engineering time.

Safety Inside using Safe Torque-Off Function
Safe Torque-off is a standard feature that can be applied through either hardwired safety or Integrated Safety via an
EtherNet/IP network. Safe Torque-Off allows you to restart your application faster after a safety-related situation.
•Safe Torque-Off functionality removes rotational power without powering down the drive.
•Built-in safety reduces wiring and saves on installation space.
•Meets ISO 13849-1 standards and provides safety ratings up to and including SIL 3/PLe.
Communications and Software
Versatile Programming and Network Solutions
•A network can be configured using
PowerFlex 527 drives for flexible configuration
capabilities.
•Built-in dual port for EtherNet/IP
EtherNet/IP is an established, broadly adopted
network that helps simplify and enhance machine
design and operation. Dual-port EtherNet/IP
connectivity supports linear and ring topologies as well
as device level ring (DLR) functionality.
The application of the CIP Safety protocol enables the
simultaneous transmission of safety and standard
control data and diagnostics information through
EtherNet/IP.
PC Programming Software
Studio 5000 Logix Designer
•PowerFlex 527 drives are designed to be used exclusively with Allen Bradley Logix controllers.
•Drives are programmed using the motion instructions in Studio 5000 Logix Designer(1).
•PowerFlex 527 drives feature drive configuration that is stored in the Logix controller, supporting fast, automatic
device replacement.
(1) Studio 5000 Logix Designer (formerly RSLogix 5000) version 24 or greater is required.
