we have a ABB AC 460V/60Hz motor run on 380V/50Hz power supply in China. The motor is connected to a ABB drive. The nameplate of motor rating is 522KW/769Amps/1790RPM/460V/60Hz. Because the V/Hz is almost the same between 460/60 and 380/50, i think the torque and FLA should be about the same between these two. My question is that which values should we enter in the VFD for motor rated power, amps, RPM, and voltage, should we enter 522KW/769Amps/1790RPM/460V/60Hz or 435KW/769Amps,1490/380/50Hz? Or they are pretty much the same?
Thanks a lot for your help.
