Basic operation procedure (PU operation)

Select a method to give the frequency command from the list below, and refer to the specified page for its procedure.
Setting the frequency on the operation panel in the frequency setting mode
Give commands by turning ON/OFF switches wired to inverter's terminals (multi-speed setting)
Setting the frequency by inputting voltage signals
Setting the frequency by inputting current signals
2.5.1 Setting the frequency on the operation panel
(example: operating at 30 Hz)
• Use the operation panel to give a start command and a frequency command. (PU operation)
The following shows the procedure to operate at 30 Hz.
Operating procedure
1.
Turning ON the power of the inverter
The operation panel is in the monitor mode.
2.
Changing the operation mode
Press the PU/EXT key to choose the PU operation mode. The PU LED turns ON.
3.
Setting the frequency
Turn the setting dial or press the UP/DOWN key until the target frequency "30.00" (30.00 Hz) appears. The indication
blinks for about 5 seconds.
While the value is blinking, press the SET key to enter the frequency. "F" and "30.00" are displayed alternately. After
about 3 seconds of alternate display, the indication returns to "0.00" (the indication of a monitored value).
(If the SET key is not pressed, the indication of the value returns to "0.00" (0.00 Hz) after about 5 seconds of blinking.
In that case, turn the setting dial or press the UP/DOWN key and set the frequency again.)
4.
Start → acceleration → constant speed
Press the RUN key to start running. The frequency value on the monitor increases according to the setting of Pr.7
Acceleration time, and "30.00" (30.00 Hz) appears on the monitor.
(To change the set frequency, return to step 3. The previously set frequency appears.)
5.
Deceleration → stop
Press the STOP/RESET key to stop. The frequency value on the monitor decreases according to the setting of Pr.8
Deceleration time, "0.00" (0.00 Hz) appears on the monitor, and the motor stops rotating.
NOTE
• To display the set frequency in the standard model, press the setting dial while the inverter runs in the PU operation mode or
in the External/PU combined operation mode 1 (Pr.79 = "3"). (Refer to
• The frequency can be set without pressing the SET key when Pr.161 Frequency setting/key lock operation selection = "1
or 11". (Refer to
