INSTALLATIONS USING NCLoad.
Open NC load (using Windows desktop shortcut)
Using the Browse option, select the operating system file (.vcn) you wish to
install (for this example we will use -NXL00005V260.VCN) into the frequency
inverter.
The first time you run NCLoad you may need to manually select the file path
(including Drive, Folder and File) for the NCLoad program as to where you
have the programming files saved, after this NCLoad should remember the
path for any future installations. Once selected press "OK".
-Set Baudrate to maximum speed "57600" (This will ensure the installation goes
the fastest.)
