3.) 3-20=0001, If the multifunction terminal is set as 10(energy saving control terminal), the output
voltage will gradually decline to ‘original voltage’ב3-21’ preset value as the terminal’ is ON.
The output voltage will rise to original voltage as the terminal is OFF.
※Note:1.The declining and rising speeds of voltage for energy saving is same as the ones for
SPEED SEARCH.
2. Energy saving mode is only available under V/F mode. (0-00 = 0002).

※Note: The external electronic components maybe interfered, more serious, even the motor
vibration due to cutting of the high carrier frequency waveform, although the inverter
provides low noise environment in running. Thusly, it is necessary to regulate the carrier
frequency.

3-24 : Amplitude(%): 0.1-20.0
3-25 : Amplitude Drop(%) : 0.0-50.0

Traverse Run is defined as adding a triangle wave to the basic operation frequency of inverter output
frequency at the preset acceleration and deceleration time. The action is as the graph below:

1) The traverse run is available as the run command and the terminal (5-00~5-05=0025) for such
operation both ON. Inverter operating, the traverse run is ready when the inverter output
frequency reaches center frequency (3-23). During acceleration to center frequency, the
acceleration time is at the originally preset value (3-02/3-06). When the traverse run is OFF or the
Inverter is OFF, the deceleration time is also at original preset value (3-03/3-07). However, in
