VFD

IfItsGotWheels said

I'd used VFDs for the better part of 20yrs. From a single 4HP unit to a 60hp unit running an entire production line of 10 3HP motors. [All Danfoss & Allen Bradley] We used the VFDs as speed controls.
The most important thing is when you're programming the drive, input all the specs from the motor you can.

I previously stated VFDs generally don't do well above 3HP... I should have specified VFDs don't do well generating the third leg of three phase power above 3HP... They are great for speed control.... I've worked with AB stuff in plants, definitely better equipment but it comes with a much higher price....
