P04.28
Voltage set through
keypad
The function code is the voltage digital setting
when "keypad" is selected as the voltage setting
channel.
Setting range: 0.0%–100.0%

P04.29
Voltage increase
time
Voltage increase time means the time needed
for the VFD to accelerate from min. output
voltage to the max. output frequency.
Voltage decrease time means the time needed
for the VFD to decelerate from the max. output
frequency to min. output voltage.
Setting range: 0.0–3600.0s

P04.31
Max. output voltage
The function codes are used to set the upper
and lower limits of output voltage.

Pull-in current 1 in
SM V/F control
When the SM VF control mode is enabled, the
function code is used to set the reactive current
of the motor when the output frequency is lower
than the frequency specified by P04.36.
