Operation by the start command of the terminal block
(external operation)
4.4.4 Perform frequency setting by analog (current input)
POINT
• Switch terminal STF(STR)-SD on to give a start command.
Assign the AU signal to any of the terminal RH, RM, RL, or STR and turn on the
•
AU signal. (Refer to page 26)
• Set "2" (external operation mode) in Pr. 79 "Operation mode selection".

1.
Power on operation mode check
For the factory setting, the inverter operates
in the external operation mode [EXT] when
powering on. Check that the operation
command indication is [EXT]. If not displayed,
press to change to the external [EXT] operation
mode. If the operation mode still does not change, set
Pr. 79 to change to the external operation mode.
(Refer to page 46)
2.
Start
Turn the start switch (STF or STR) on.
RUN of operation indication flickers.
CAUTION
When both the forward switch and reverse
switch are on, the inverter will not start.
Also, if both switches turn on while
running, the inverter decelerates to stop.
3.
Acceleration
Perform 20mA input.
The frequency value on the
indication increases according to
Pr. 7 "Acceleration time" until
60.0Hz is displayed.
