External operation
Basic settings
5 - 40
Possible faults:
●
The motor will not rotate.
– Check that the EXT lamp is lit. The external operation mode is valid when Pr. 79 = 0 (initial
value) or 2. Use the PU/EXT key to change into the external operation mode.
– The AU signal must be turned on.
– Check that wiring is correct.

Operate the inverter by using the analog current input
NOTE
One of Pr. 178 to Pr. 184 "AU terminal function selection" must be set to "4" (AU signal) (initial
value). (Refer to section 6.10.1.)
NOTE
Change the frequency (0 Hz) of the minimum value of potentiometer (at 4 mA) by adjusting the
frequency in calibration parameter C5 "Terminal 4 frequency setting bias frequency". (Refer to sec-
tion 6.16.3.)
햲
Power on
operation mode check
For the initial 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 the PU/EXT key
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 section 5.1.6).
햳
Start
Turn the start switch (STF or STR) on.
When the frequency command is not given,
"RUN" flickers fast.
햴
Acceleration
constant speed
Perform 20 mA input. The frequency value on the
indication increases according to Pr. 7
"Acceleration time" until 50.00 Hz is displayed.
햵
Deceleration
Perform 4mA input. The frequency value on the
indication decreases according to Pr. 8
"Deceleration time" and displays "0.00" (0.00 Hz)
when the motor is stopped.
"RUN" flickers fast.
햶
Stop
Turn the start switch STF or STR off.
