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.
