2.5 Basic operation procedure (PU operation)
2.5.3
Setting the frequency using an analog signal
(voltage input)
• Use the RUN key on the operation panel to give a start command.
• Use the frequency setting potentiometer to give a frequency command (by connecting it to terminals 2 and 5 (voltage input)).
• Set
Pr.79 Operation mode selection
= "4" (External/PU combination operation mode 2).
[Connection diagram] (The inverter supplies 5 V power to the frequency setting potentiometer via terminal 10.)
The following shows the procedure to operate at 60 Hz.
Operating procedure
1.
Turning ON the power of the inverter
The operation panel is in the monitor mode.
2.
Changing the operation mode
Set "4" in
Pr.79
. The PU LED and EXT LED turn ON. (To change the setting, refer to
.)
3.
Start
Press the RUN key. The RUN LED blinks as no frequency command is given.
4.
Acceleration
→
constant speed
Turn the frequency setting potentiometer clockwise slowly to full. The frequency value on the monitor increases
according to the setting of
Pr.7 Acceleration time
, and "60.00" (60.00 Hz) appears on the monitor.
5.
Deceleration
Turn the frequency setting potentiometer counterclockwise slowly to full. 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. The RUN LED blinks.
6.
Stop
Press the STOP/RESET key. The RUN LED turns OFF.
NOTE
• To change the frequency (60 Hz) at the maximum voltage input (initial value: 5 V), adjust
Pr.125 Terminal 2 frequency setting
gain frequency
.
• To change the frequency (0 Hz) at the minimum voltage input (initial value: 0 V), adjust the calibration parameter
C2 (Pr.902)
Terminal 2 frequency setting bias frequency
.
• When terminal 10 is used, the maximum output frequency may fluctuate in a range of ±6 Hz due to fluctuations in the output
voltage (5 ±0.5 VDC). Use
Pr.125
or
C4 (Pr.903)
to adjust the output frequency at the maximum analog input as required.
