Commons Issues with Allen-Bradley PowerFlex Drives
For detailed PowerFlex 70 information: For Allen-Bradley Drives Technical Support:. In this manual we refer to the PowerFlex 70 Adjustable Frequency AC Drive as; drive, PowerFlex 70 or PowerFlex 70 Drive. To help differentiate parameter names and LCD display text from other text, the following conventions will be used. PowerFlex® 753 AC Drives are cost-effective and easy to use in general purpose applications requiring safety features. They come standard with built-in I/O, which is ideal for machine builders and system integrators who want to reduce engineering costs, deliver machines to market faster, and meet end user demand for more productive machines. The VFD is giving Ground Fault. What might be the possible reasons? The VFD is Allen Bradley PowerFlex 400 1) Any Phase inside the terminal of motor is touching with the motor frame or body. 2) An phase inside the connection terminal strip of VFD is touching with metallic frame or metallic. The codes will appear in these parameters in the order they occur (b007 Fault 1 Code = the most recent fault). Repetitive faults will only be recorded once.

Problems and Solutions for Allen-Bradley PowerFlex Drives
- Contamination/Corrosion
- Disconnect power and remove contamination (metal shavings, dust) with compressed dry air. The Allen-Bradley Powerflex drive should be sent in for service if it’s soaked with oil or other liquid contaminants.
- Loose connections
- Electronics are limited to their wiring. Vibrations, physical manipulation or relocation may loosen terminal connections. Verify and secure all terminal connections.
- Missing power phase
- Check input voltage and verify power is on all phases.
- Bad cables
- Over time and after constant use, cables will wear out from physical damage and contamination. If you have haven’t swapped out your cables in a while, secure a new cable and try again.
- Seized cooling fans
- Overheating is the biggest enemy to electronic circuitry. Proper ventialtion requires that fans have been cleaned and devoid of any debris.
- Wrong parameters
- This issue can occur when system memory leaks due to voltage transients and the values change. Backup the parameters using the HIM and reset the drive to factory default, then restore the correct parameters.
- Binded load
- This will usually cause an overcurrent fault. Check gear, fans, pulleys or worm gears for proper operation.
