Needs a Power board for ATV71HC11N4
ATV71 and ATV61
All models, all serial numbers
Power board not functional
The Power board for these drive is VX5A1HC1113.
It is required to check the Serial number of the drive before ordering the Power Board.
If the 8th digit in the serial number is 2, the drive was built using Fuji IGBT's instead of the standard Mitsubishi IGBT's. A drive with Fuji IGBT's requires a modified version of the Power board (VX5A1HC1113F). IGBT, and gate driver board parts also will have an F at the end.
