  1. Powerflex 40P Failures

    plcxmas replied to BobLfoot's topic in Allen Bradley / Rockwell Automation

    We had three 40P's that would not power the Ecom card, I moved the Ecom card to another VFD and it died. So it seems that the Ecom card is smoking the power supple in the VFD. This was using 22D-D4PON104 vfd'S series A, do to the AB rebuild price they are now through away drives. All three drives died at the same time.
