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.
Maximize your system performance and productivity by taking advantage of the following key features offered in a
PowerFlex 527 drive.
PowerFlex 527 AC Drives Feature
Design
• Designed to be used exclusively with Allen-Bradley Logix controllers.
• Designed for machine applications – such as pumps, fans, and in-feed and out-feed conveyors – that need speed
control for induction motors.
• Logix integration helps deliver a high level of motor coordination.
• Built-in dual-port EtherNet/IP supports multiple network topologies and Device Level Ring functionality.
• Built-in hardwired Safe Torque-off. SIL 3 / PLe Cat 3.
• Integrated Safety – controller-based safety delivered via EtherNet/IP. SIL 3 / PLe Cat 3.
• Reduce your spare parts with a standard control module that can be used across the entire power range.
• Support for an incremental encoder accessory card without affecting footprint.
Packaging and Mounting
• Installation can be quick and easy using the DIN rail mounting feature on A, B, and C frame drives. Panel mounting
is also available, providing added flexibility.
• Zero Stacking™ is allowed for ambient temperatures up to 45 °C, saving valuable panel space.
• Integral filtering is available on all 200V and 400V ratings, providing a cost-effective means of meeting EN61800-3
Category C2 and C3 EMC requirements. External filters provide compliance to EN61800-3 Category C1, C2, and
C3 EMC requirements for all PowerFlex 520-Series ratings.
• An optional IP 30, NEMA/UL Type 1 conduit box is easily adapted to the standard IP 20 (NEMA Type Open)
product, providing increased environmental ratings.
Optimized Performance
• Removable MOV to ground provides trouble-free operation when used on ungrounded distribution systems.
• A relay pre-charge limits inrush current.
• Integral brake transistor, available on all ratings, provides dynamic braking capability with simple low cost brake
resistors.
