Function Group 1
 Set the amount of output voltage to be reduced in F40.
 Set as the percent of Max output voltage.
 For fan or pump applications, energy consumption can be dramatically reduced by decreasing
the output voltage when light or no load is connected.

 This is used to prevent possible fault from occurring if the inverter outputs the voltage during
operation after the load is removed.
 The inverter estimates the motor rpm based on output current. Therefore, detecting exact
speed is difficult.
