Fig. 5-27: Operate the inverter by using the analog voltage input
NOTES When you want to operate in the external operation mode always at powering on or when you
want to save the trouble of input, set "2" (external operation mode) in Pr. 79 "Operation mode
selection" to choose external operation mode always.
Pr. 178 "STF terminal function selection" must be set to "60" (or Pr. 179 "STR terminal function
selection" must be set to "61"). (All are initial values.)
Change the frequency (0 Hz) of the minimum value of potentiometer (at 0 V) by adjusting the fre-
quency in calibration parameter C2 "Terminal 2 frequency setting bias frequency". (Refer to section
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 "0" to change to the external operation
mode. (Refer to section 5.1.6).
햳
Turn the start switch (STF or STR) on.
When the frequency command is not given,
"RUN" flickers fast.
햴
Acceleration constant speed
Turn the potentiometer (frequency setting
potentiometer) clockwise slowly to full.
The frequency value on the indication increases
according to Pr. 7 "Acceleration time" until 50 Hz
is displayed.
햵
Deceleration
Turn the potentiometer (frequency setting
potentiometer) counterclockwise slowly to full.
The frequency value on the indication decreases
according to Pr. 8 "Deceleration time" and
displays "0.00" (0.00 Hz) to stop the motor.
"RUN" flickers fast.
햶
Stop
Turn the start switch (STF or STR) off.
"RUN" turns off.
