Replacing DOL drive with Novomet VFD
We installed VFD Novomet, and problems began. With 48 Hz, the load was 98%, although previously on a DOL ("clapper" / bang-bang) VSD at 50 Hz it was 65%. The settings are all correct..who knows?

Have you recalculated the tap for the acceleration curve? Calculation of soldering was discussed here: Sizing VSD for ESP motor power
