Changing display to read output speed in percent (%) of full speed.

The display is factory defaulted to show the inverter output frequency in Hz. If desired, the display can be changed to show the output frequency as a percentage of full speed. To do this parameter Cn-28must be changed from (00000) to (00001) as follows:

To set parameter Cn-28 = 1
