4.2 Detailed Function Description
This function code defines the maximum
output voltage of VFD. When output feedback
disconnection happens and voltage increases
without control and lost protection, this
function can limit the output voltage within
the allowed range, which ensures the safe of
work load.

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.
