setting voltage
The function code is the voltage digital set value when
the voltage setting channel is selected as "keypad
selection".
Setting range: 0.0%–100.0%

P04.29
Voltage
increasing
time
Voltage increasing time is the time when the VFD
accelerates from the output minimum voltage to the
output maximum voltage.
Voltage decreasing time is the time when the VFD
decelerates from the output maximum voltage to the
output minimum voltage.
Setting range: 0.0–3600.0s
