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).
• Setting Pr.79 Operation mode selection = "3" enables multi-speed operation.
• If the STOP/RESET key on the operation panel is pressed during the External operation, the inverter stops and the PU stop
warning is activated ("PS" appears on the LCD display of the operation panel.) To reset the PU stop warning, turn OFF the
start switch (STF or STR signal), and then press the PU/EXT key. (Refer to
page 162 .)

2.6.2 Setting the frequency and giving a start command
with switches (multi-speed setting) (Pr.4 to Pr.6)
• Turn ON the STF/STR signal to give a start command.
• Turn ON the RH, RM, or RL signal to give a frequency command (multi-speed setting).
[Connection diagram]
The following shows the procedure to operate at a high speed (60 Hz).
Operating procedure
1.
Turning ON the power of the inverter
The operation panel is in the monitor mode.
2.
Setting the frequency
Turn ON the high-speed switch (RH signal).
3.
Start → acceleration → constant speed
Turn ON the start switch (STF/STR signal). 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. When the RM signal is turned ON, 30 Hz is displayed. When the
RL signal is turned ON, 10 Hz is displayed.
4.
Deceleration → stop
Turn OFF the start switch (STF/STR signal). 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
turns OFF. Turn OFF the high-speed switch (RH signal).
