Rockwell Automation Powerflex 700 Manual

1. Hi, I'm working with about ten Powerflex 700, on 480V. There is nothing in the powerflex700 manual about that fault, and any other. RA Knowledgebase documents 39435 and 33902 list those fault codes, saying they are.
2. PowerFlex 750-Series AC Drives User Manual, which includes wiring diagrams, start-up procedures, parameter lists, fault/alarm codes.

Description of New or Updated Information Page Removed the product certifications and specifications from Appendix A. All certification and specification information is located in the PowerFlex 700 Adjustable Frequency AC Drive Technical Data, publication 20B- TD001.

If a fault code appears, refer to Chapter 3. Proceed to “Start-Up the Drive”. Start-Up the Drive. The PowerFlex 700H drive is designed so that start up is.

In this manual we refer to the PowerFlex 700 Adjustable Frequency AC Manual Conventions Drive as; drive, PowerFlex 700 or PowerFlex 700 Drive. To help differentiate parameter names and LCD display text from other text, the following conventions will be used: –. Appendix Motors Drive Frame Sizes Similar PowerFlex 700 drive sizes are grouped into frame sizes to simplify spare parts ordering, dimensioning, etc.

A cross reference of drive catalog numbers and their respective frame size is provided in the Catalog Number Explanation on. The most common causes are:. Wiring AC line to drive output or control terminals.

Improper bypass or output circuits not approved by Allen-Bradley. Output circuits which do not connect directly to the motor. Preface ATTENTION: The “adjust freq” portion of the bus regulator function is extremely useful for preventing nuisance overvoltage faults resulting from aggressive decelerations, overhauling loads, and eccentric loads.

It forces the output frequency to be greater than commanded frequency while the drive's bus voltage is increasing towards levels that would otherwise cause a fault.
