A174 [Maximum Voltage] can be set anywhere.
Settings greater than P031 [Motor NP Volts] define a point on the V/Hz curve.
Settings less than P031 [Motor NP Volts] function as limits only and do not change the V/Hz curve.
P034 [Minimum Freq] can be set anywhere.
Functions as a limit only and does not change the V/Hz curve.
P035 [Maximum Freq] can be set anywhere.
Settings greater than P032 [Motor NP Hertz]
define a point on the V/Hz curve.
P035 [Maximum Freq] can be set anywhere.
Settings less than P032 [Motor NP Hertz] function
as limits only and do not change the V/Hz curve.
