Common 20G11RD5P0AA0NNNNN failures

Failure patterns we regularly see on PowerFlex 755 AC drive hardware like the 20G11RD5P0AA0NNNNN:

Drive will not power up: control power supply or precharge circuit failure
Hardware overcurrent (F12) or ground fault (F13) from a failed IGBT / power structure
DC bus undervoltage / overvoltage (F4 / F5) from capacitor aging or regen energy
Heatsink overtemperature (F8) from failed fans or blocked airflow
Main control board or option module faults (EtherNet/IP, safety, feedback cards)

Repair or replace?

ReplaceReplace the 20G11RD5P0AA0NNNNN when the motor is down and a same-rating PowerFlex 755 AC drive is on the shelf. Upload the parameters, download them to the new drive, and it is back on the motor. At 3 Hp the 20G11RD5P0AA0NNNNN is a small drive, so a replacement often costs little more than a repair. Order the exact 20G11RD5P0AA0NNNNN. The catalog number sets the 3 Hp, 480V AC rating, and a different suffix changes it. We source the 20G11RD5P0AA0NNNNN on request, so weigh that lead time against a repair turnaround.

RepairRepair the 20G11RD5P0AA0NNNNN when a replacement is hard to source or the rating is large enough that a rebuild is clearly cheaper. Power modules, bus capacitors, precharge resistors and fans are replaced and the drive is run under load before it ships back. The two 20G11RD5P0AA0NNNNN symptoms we see most often are “Drive will not power up” and “Hardware overcurrent (F12) or ground fault (F13)”. If a replacement is already installed, repairing the failed 20G11RD5P0AA0NNNNN gives you a tested spare on the shelf for the next failure. Our estimated $1,440.00 repair of the 20G11RD5P0AA0NNNNN includes full-function testing and a 1-year warranty.
