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. The PU
operation and External/PU combined operation using keys are not available for the IP67 model as neither the operation panel
keys or the parameter unit can be used.
Method to give the frequency command
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.
