Could you explain the workings of this system. How does the inverter measure the power supply, from the diagram it just looks like 2 inverters driving 2 motors that are coupled together. Please elaborate. Ben

Is this a dyno set up? Where one drive and motor turns the gear box and the gearbox turns the motor in regeneration? You show common DC bus configuration. If the 3G3RV is the same KVA/HP rating of the Siemens drive, I see no problem with using it. On the side of the drive there may also be numbers begining with CIMR. Could you provide them? Also, what is the actual Siemens drive ratings. Look at part number, input amps and output amps. You want the Omron drive to be as close as possible to the Siemens drive.
