If a VFD (PowerFlex) is running on a 440VAC/3p supply (I know, odd voltage). Can you still use with a 460VAC/3p motor?
According to the tech specs for the 755 drive it states:
It sounds like I can operate with a derating on the drive because: 460VAC - 46VAC = 414 VAC.
I'm contacting AB TechConnect about thought I'd ask here as well
According to the tech specs for the 755 drive it states:
Page 11 - Drive full power = nominal motor voltage (460VAC) to drive rated voltage (480VAC) + 10% of drive (48VAC)
Page 11 - drive operating ragne = lowest nominal motor voltage (460VAC) - 10% (46VAC) to drive rated voltage (480VAC) + 10% (48VAC) output is linearly derated when actual line voltage is less than nominal motor voltage
