Basic operation procedure (External operation)
Basic operation
4 - 26
4.6.3
Setting the frequency with analog signals (voltage input)
Connection diagram
(The inverter supplies 5 V power to the frequency setting potentiometer (terminal 10).)
쑶
NOTES
Switch ON the STF (STR) signal to give a start command.
Use the potentiometer (frequency setting potentiometer) to give a frequency command (by con-
necting it across terminals 2 and 5 (voltage input)).

Frequency setting by analog voltage input
Example
쑴
Operation example: Operate at 60 Hz.
Operation
Screen at power-ON
The monitor display appears.
Start
Turn ON the start switch (STF or STR). [FWD] or [REV] flickers as no frequency command is given.
Acceleration
➔
constant speed
Turn the potentiometer (frequency setting potentiometer) clockwise slowly to full. The frequency value on the
indication increases in Pr. 7 "Acceleration time", and "
" (60.00 Hz) appears. [FWD] indicator is lit during
the forward rotation, and [REV] indicator is lit during the reverse rotation.
#
Deceleration
Turn the potentiometer (frequency setting potentiometer) counterclockwise slowly to full. The frequency value
on the indication decreases in Pr. 8 "Deceleration time", and the motor stops rotating with "
" (0.00 Hz)
displayed.
,
Stop
Turn OFF the start switch (STF or STR). [FWD] or [REV] indicator turns OFF.
Tab. 4-17:
Operate the inverter by using the analog voltage input
NOTES
When both the forward rotation switch (STF) and the reverse rotation switch (STR) are ON, the
motor cannot be started. If both are turned ON while the inverter is running, the inverter deceler-
ates to a stop.
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.)
