Repair or replace?

ReplaceReplace the 20G1AND156JA0NNNNN 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. A replacement 20G1AND156JA0NNNNN is sourced on request, so weigh the sourcing lead time against a repair turnaround.
RepairAt 125 Hp, the 20G1AND156JA0NNNNN 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 20G1AND156JA0NNNNN gives you a tested spare on the shelf for the next failure. Every 20G1AND156JA0NNNNN repair is fully function-tested and covered by a 1-year warranty.
