4.17.2 Setting the frequency by analog input (voltage input)

POINT
· Switch ON the STF (STR) signal to give a start command.
· Use the potentiometer (by connecting terminal 2 and 5) to give a frequency command.
[Connection diagram]
(The inverter supplies 5V of power to frequency setting potentiometer. (Terminal 10))
Operation example Performing operation at 60Hz.
Operation
1. Screen at power-ON
The monitor display appears.
2. Start
Turn the start switch (STF or STR) ON.

motor cannot start.
If both are turned ON while the motor is running, the motor
decelerates to a stop.
3. Acceleration → constant speed
Turn the potentiometer (frequency setting potentiometer)
clockwise slowly to full.
The frequency on the display increases in the Pr.7 Acceleration
time, and "
" (60.00Hz) appears. [FWD] indicator is lit
during forward rotation, and [REV] indicator is lit during reverse
rotation.
4. Deceleration
Turn the potentiometer (frequency setting potentiometer)
counterclockwise slowly to full.
The frequency on the display decreases in the Pr. 8 Deceleration
time, and the motor stops rotating with "
displayed. [FWD] indicator or [EXT] indicator flickers.
5. Stop
Turn the start switch (STF or STR) OFF.
[FWD] indicator or [REV] indicator turns OFF.
