Motor capacity and input voltage — sizing this drive for the load
The VFD055E43A is a Delta VFD-E series drive rated for 7.5 HP (5.5 kW) motor output, fed from a 460V three-phase mains input. That puts it squarely into the 5.5 kW constant-torque class — common for pumps, fans, and light conveyors in North American 480V plants.
The 'A' suffix in the version code indicates the standard drive variant; no special firmware or option board is baked in.
