PowerFlex 40P VFD
Hi everyone,
PowerFlex 40P AC drives are a line of adjustable frequency drives (AFDs) made by Allen-Bradley/Rockwell Automation that are used to control the speed of three-phase AC motors. These drives are designed to be compact and easy to use, and they offer a wide range of features and options to suit a variety of applications. Some of the key features of the PowerFlex 40P drives include built-in EMC filters, multi-language LCD keypad, and multiple control and communication options. They can be used in a variety of industrial settings such as conveyors, fans, pumps, and other process control applications.
Allen Bradley PowerFlex® 40P AC Drive
The PowerFlex 40P AC drive is a compact and cost-effective solution for closed loop control and category 3 Safe-off. It features improved performance with a standard encoder/pulse train input for closed loop control of speed or position, and improved ride through operation down to 1/2 line voltage. The drive is optimized for common DC bus installations and has enhanced control of internal pre-charge.
The PowerFlex 40P AC drive also includes DriveGuard® category 3 Safe-off option (Series B) for increased safety and productivity. It offers flexible packaging and mounting options, including panel mount NEMA/UL Type 1/IP30 and NEMA/UL Type 4/IP66 (with like enclosure) using plate/flange drives.
In terms of start-up, programming, and operation, the PowerFlex 40P drive can be programmed using an external HIM or via the resident DSI connection and PC programming tools such as DriveTools™ SP, DriveExplorer™, and Pocket DriveExplorer™. There are also StepLogic™ wizards available to assist in setup of position or velocity StepLogic programming.
Specific Textile & Fiber Applications
The PowerFlex 40P AC drive has specific functions for textile and fiber applications, including the ability to ratio speed given a single speed reference, and flexible communication options to multiple field bus networks. Additionally, it has a standard NEMA/UL Type 1/IP30 panel mount and encoder feedback with speed regulation of +/-0.3% of base speed across an 80:1 speed range. The drive can be used in applications such as drafting machines, carding machines, ring spinning machines, roving machines, synthetic fiber spinning machines, and more.
Safety Inside
DriveGuard® Category 3 Safe-off Option (Series B)
With the DriveGuard option, category 3 Safe-off combines safety and productivity with zone control and cost savings through the reduction of components. The PowerFlex 40P AC drive with the Allen-Bradley® DriveGuard relay board option is a certified safety solution for AC drive control per EN954-1.
Flexible Packaging and Mounting Options
Versatile packaging options allow for panel mount NEMA/UL Type 1/IP30 as well as NEMA/UL Type 4/IP66 (with like enclosure) using the plate/flange drives. Plate drives also allow for a reduction in overall enclosure size based on a 75% reduction in enclosed Watts.
Start Up, Programming and Operation
PowerFlex 40P drive programming is achieved by the use of an external HIM or via the resident DSI connection and PC programming tools.
• DriveTools™ SP
• DriveExplorer™
• Pocket DriveExplorer™
StepLogic™ wizards available for DriveTools SP and DriveExplorer (Lite or Full) assist in setup of position or velocity StepLogic programming.
Premier Integration with PowerFlex Drives
For simplified AC drive start-up and reduced development time using the Allen-Bradley® Logix control platform, we’ve integrated PowerFlex® AC drive configuration with RSLogix™ 5000 software. This single-software approach simplifies parameter and tag programming while still allowing stand-alone drive software tool use on the factory floor.
Simple Positioning
The PowerFlex 40P AC Drive comes standard with configurable dual channel (Quadrature) incremental Encoder or Pulse Train Input.
The drive can provide 5V or 12V DC supply to the encoder and can accept 5V/12V/or 24V DC pulse inputs. The PowerFlex 40P AC Drive can be used as an independent position controller for basic positioning or as part of an outer position control loop using an improved analog input.
TEXTILE & FIBER APPLICATIONS
The PowerFlex 40P AC drive has specific functions added to make it ideal for low cost Fiber and Textile applications. The addition of the embedded Pulse Train Input provides economical and configurable speed control. Drives can also be set up to ratio speed given a single speed reference. With flexible communication options to multiple field bus networks and plate drive capability allowing for a reduction in cabinet size, the PowerFlex 40P AC drive is an ideal fit for the diverse needs of your Fibers and Textile applications.
