Step of Up/Down Function (Hz):
01-07: Up/Down (Hz) 0.00 ~ 5.00
There are two modes covered below:
1 .01-07 = 0.00, the operation is just as the original one. When the UP terminal is ON, the frequency
increases while the DOWN terminal is ON, the frequency decreases. (Refer to the following
graph).
2. 01-07 = 0.01 to 5.00, and UP/ DOWN terminal ON, is equivalent to a step increase/ decrease at
the increment frequency in 01-07. If UP/DOWN is pressed over 2 seconds, the original
UP/DOWN mode is restored (Please refer to the following diagram)
Stop Mode Using Up/Down:
01-08 : Up/Down keep Frequency mode
0 : When Up/Down is used, the preset frequency is held as the inverter stops,
and the UP/Down function is disabled.
1 : When Up/Down is used, the preset frequency is reset to 0 Hz as the inverter stops.
2 : When Up/Down is used, the preset frequenc
is held as the inverter stops, and the
UP/Down is available.
1. 01-08=0 : the inverter will accelerate to the speed set in parameter 03- 01 as receiving the Run
command and run at such certain speed. The inverter begins to accelerate (decelerate) as the UP
(Down) terminal is energized. The inverter will hold the speed as the UP/DOWN command
released. When the Run Signal releases, the inverter will ramp stop or stop which determined by
the 04-01. It will store the frequency when the run signal is removed. UP/DOWN keys are idle
