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.
• The initial value is 60 Hz for terminal RH in Group 1 (50 Hz in Group 2), 30 Hz for terminal RM, and 10 Hz for terminal RL. (To
change the settings, use
Pr.4, Pr.5
, and
Pr.6
, respectively.)
• In the initial setting, if two or more speed switches (signals) are simultaneously turned ON, priority is given to the switch (signal)
for the lower speed. For example, when both RH and RM signals turn ON, the RM signal (
Pr.5
) has the higher priority.
• Up to 15-speed switching operation can be performed.
• Up to two external input terminals are available for the Ethernet model. Use
Pr.178 STF/DI0 terminal function selection
and
Pr.179 STR/DI1 terminal function selection
to assign the functions to terminals DI0 and DI1.

Setting the frequency using an analog signal
(voltage input)
• Turn ON the STF/STR signal to give a start command.
• Use the frequency setting potentiometer to give a frequency command (by connecting it across terminals 2 and 5 (voltage
input)).
[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.
Start
Turn ON the start switch (STF/STR signal). The RUN LED on the operation panel blinks as no frequency command
is given.
3.
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. The RUN LED
is ON during forward rotation and blinks slowly during reverse rotation.
4.
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.
5.
Stop
Turn OFF the start switch (STF/STR signal). The RUN LED turns OFF.
