Thread Starter
Hello everyone,
We are using a Powerflex 753 VFD to control a motor which lifts and descends loads. The drive goes into fault code 12 (HW Overcurrent) and code 36 (SW Overcurrent) multiple times while its descent in the loaded condition. The drive does not go into fault when:
1. It ascends or descends in no load.
2. Ascends in load condition.
Therefore the fault occurs only in one direction under loaded condition.
I have google searched and tried changing a few parameters [Parameter 43 (Flux Up Enable) and Parameter 44 (Flux Up Time), Parameter 70 (Autotune) and Parameter 621 (Slip RPM at FLA) to 0], but it didn't affect the faults.
Any ideas why? Any solutions?

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.
