0.0~100.0%*motor rated voltage
80.0%
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.
F5.18
controller adjustment cycle of voltage
closed-loop output
0.01~10.00s
0.10
This function code indicates the speed of voltage
adjustment. Decrease this parameter if the voltage
response is slow.
F5.19
Voltage rising time
0.1~3600.0s
10.0
F5.20
Voltage declining time
0.1~3600.0s
10.0
This function code defined the rising and falling time
of voltage in the V/F fully separated control mode, i.e.
mode 2.
F5.21
Voltage feedback disconnection treatment
0~2
0
0: alarm and keeping running with the voltage in
disconnection moment.
1: alarm and decrease the voltage to the amplitude
limiting voltage.
2: protection action and coast to stop.
F5.22
Detection value of voltage feedback
disconnection
0.0~100.0%*motor rated voltage
2.0%
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.
F5.23
Detection time of voltage feedback
disconnection
0. 0~100.0s
10.0
After voltage feedback disconnection, the duration
time before protection action.

0.0~100.0%* motor rated voltage
80.0%
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.
