This function defined the maximum voltage point when starting the equipment with voltage and frequency curve. An
appropriate setting of this function could prevent voltage overshoot effectively to ensure reliable operation.

The maximum value of specified voltage works as the upper limit of feedback disconnection detection value. Within the
time of feedback disconnection detection, when voltage feedback value is continuously lower than feedback
disconnection detection value, VFD will respond with protection action according to F5.21 setting.
