Allen-Bradley PowerFlex 40P AC Drive

Description

MILWAUKEE— OEMs and end users who require space savings and easy-to-use AC drives that can provide application flexibility, basic positioning and Category 3 Safe-off, have a new cost-effective option with the introduction of the Allen-Bradley PowerFlex 40P AC drive from Rockwell Automation.

The PowerFlex 40P AC drive features encoder or pulse train input, allowing configured closed loop control for improved speed regulation, basic position control, or other pulse inputs for motor control. “The PowerFlex 40P AC drive is an excellent solution for automation customers requiring basic or simple positioning,” said Paul Nolden, program manager, Standard AC Drives, Rockwell Automation. With the use of the StepLogic function, the PowerFlex 40P AC drive can act as an independent position controller for simple time, digital input or communications-based index positioning applications, eliminating the need for a separate position controller. “The PowerFlex 40P drive reduces change-over time by allowing the drive to control the application position parameters,” said Nolden.

The PowerFlex 40P drive also features an optional DriveGuard safety relay providing a certified solution that meets EN954-1, Category 3 (Safe-off and protection against restart). “This is the first drive in its class to offer a safety solution inside the product, reducing external hardware costs and simplifying wiring,” said Nolden. “Safe-off allows the user to shut down a section of an application for maintenance, keeping the remaining sections running, without removing power to the drive and I/O.” With the DriveGuard option, Category 3 Safe-off combines safety and productivity with zone control and cost savings by reducing components.

The PowerFlex 40P also includes specific features that expand the PowerFlex family’s capabilities for the textile and fibers industry. “With specific features like P-Jump, traverse, speed ratio over communications and Common Bus configuration, and output frequency up to 500Hz, the PowerFlex 40P AC drive is a perfect solution for low-cost fiber and textile applications,” said Nolden. The PowerFlex 40P drive also comes in a plate drive version that reduces the cabinet size by allowing the drive to be mounted to an external heatsink.

PowerFlex 40P AC drives are cost-effective alternatives for speed control or basic positioning of applications such as diverters, smart conveyors, packaging machines, palletizers and drafting machines, as well as fibers spinning applications such as ring spinning machines and synthetic fiber spinning machines.

The drive, available globally, is available in power ratings from 0.4 to 11 kW (0.5 to 15 HP) and in voltage classes of 240, 480 and 600 volts.
