Common 20G11ND052JA0NNNNN failures

Failure patterns we regularly see on PowerFlex 755 AC drive hardware like the 20G11ND052JA0NNNNN:

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)
HIM display blank or unresponsive
Input phase loss (F17) and precharge faults following a line-side event

Repair or replace?

ReplaceReplace the 20G11ND052JA0NNNNN 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. Stick with the exact 20G11ND052JA0NNNNN. The suffix sets the 40 Hp, 480V AC rating, so a near match is a different unit. We have the 20G11ND052JA0NNNNN in stock. Order before 5:00 PM Central and it ships the same day.

RepairAt 40 Hp, the 20G11ND052JA0NNNNN is in the range where repair typically costs well under half of a new drive. Power modules, bus capacitors, precharge resistors and fans are replaced and the drive is run under load before it ships back. Most 20G11ND052JA0NNNNN units reach our bench with one of two symptoms: “Drive will not power up” or “Hardware overcurrent (F12) or ground fault (F13)”. Already swapped it out? Repairing the failed 20G11ND052JA0NNNNN turns it into a tested spare on the shelf for the next failure. Our estimated $2,450.00 repair of the 20G11ND052JA0NNNNN includes full-function testing and a 1-year warranty.
