Hello All, I used to control 15HP pump motor with reversible contactors and overloads. What advantage will I have if I go for VFD solution instead. Any cost saving? Will I eleminate overload?maybe other advantages? I can run pump slower by reducing frequency, this is small advantage to me...

Thank you for reply, In my post I tryed to explain that swapping phase didn't work, L1 with L2, L1 with L3 Tryed all the combinations. I do this on a daily basis, with different motors, never had a problem! This is not a typical problem.

Hi All, I have the stangest problem, I cant change Rotation of 3PH motor. Swapping 2 Phases together didn't help. We used the same type of motor (it looks the same but different name Franklin or so.)and the same label with connection diagrame, it always works, but not this time, and its not...
