P04.28
Set voltage value
via keypad
When the channel for voltage setup is set to
"keypad", the value of this function code is digital
voltage set value.

P04.29
Voltage increase
time
Voltage increase time means the time needed
from outputting the min. voltage to accelerating to
output the max. voltage.
Voltage decrease time means the time needed
from outputting max. voltage to outputting the
min. voltage
