Repair or replace?

ReplaceReplace the 20G 11ND05 2JA0 NNNNN when the motor is down and a same-rating PowerFlex 755 AC drive is on the shelf: upload the parameters, download to the new drive and it is back on the motor. We have the 20G 11ND05 2JA0 NNNNN in stock, so a replacement ships the same business day when ordered before 5:00 PM Central.
RepairAt 40 Hp, the 20G 11ND05 2JA0 NNNNN 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. If a replacement is already installed, repairing the failed 20G 11ND05 2JA0 NNNNN gives you a tested spare on the shelf for the next failure. Our estimated $2,450.00 repair of the 20G 11ND05 2JA0 NNNNN includes full-function testing and a 1-year warranty.
