[Maximum Voltage] can be set anywhere.
If it is > [Motor NP Volts] then it denes a point on the V/Hz curve
[Maximum Freq] can be set anywhere.
If it is > [Motor NP Hertz] then it denes a
point on the V/Hz curve
[Maximum Voltage] can be set anywhere.
If it is < [Motor NP Volts] then it functions as a limit only
(does not change the V/Hz curve)
