2. Basic Operation
2.6 Basic operation procedure (External operation)
NOTE
• When both the forward rotation start switch (STF signal) and the reverse rotation start switch (STR signal) are turned ON, the
motor cannot be started. If both are turned ON while the inverter is running, the inverter decelerates to a stop.
•
Pr.178 STF/DI0 terminal function selection
must be set to "60" (or
Pr.179 STR/DI1 terminal function selection
must be
set to "61") (initial value).
• 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.

Changing the frequency (initial value: 60 Hz) at the
maximum voltage input (initial value: 5 V)
• Change the maximum frequency.
The following shows the procedure to change the frequency at 5 V from 60 Hz (initial value) to 50 Hz using a frequency setting
potentiometer for 0 to 5 VDC input. Set 50 Hz in
Pr.125
so that the inverter outputs 50 Hz at 5 V input.
Operating procedure
1.
Selecting the parameter
Turn the setting dial or press the UP/DOWN key until "P.125" (
Pr.125
) appears.
Press the SET key to show the present set value (60.00 Hz).
2.
Changing the maximum frequency
Turn the setting dial or press the UP/DOWN key to change the value to "50.00" (50.00 Hz).
Press the SET key to confirm the setting. "50.00" blinks.
3.
Selecting the mode and the monitor item
Press the MODE key twice to select the monitor mode and to monitor a frequency.
4.
Start
Turn ON the start switch (STF/STR signal), and turn the frequency setting potentiometer clockwise slowly to full.
(Refer to steps 2 and 3 in
The motor is operated at 50 Hz.
NOTE
• To set the frequency at 0 V, use the calibration parameter
