Setting the frequency by analog input (current input)
· Switch ON the STF (STR) signal to give a start command.
· Switch ON the AU signal.
· Set "2" (External operation mode) in Pr. 79 Operation mode selection.
Performing operation at 60Hz.
1. Screen at power-ON
The monitor display appears.
Check that the terminal 4 input selection signal (AU) is ON.
Turn the start switch (STF or STR) ON.
[FWD] or [REV] is flickering as no frequency
When both of STF and STR signals are turned ON, the motor
If both are turned ON while the motor is running, the motor
decelerates to a stop.
3. Acceleration → constant speed
Perform 20mA input.
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.
Input 4mA or less.
The frequency on the display decreases in the Pr. 8 Deceleration
time setting, and the motor stops rotating with "
[FWD] indicator or [EXT] indicator flickers.
Turn the start switch (STF or STR) OFF.
[FWD] indicator or [REV] indicator turns OFF.
Pr. 184 AU terminal function selection must be set to "4" (AU signal) (initial value). (Refer to Chapter 4 of
Forward rotation start
Reverse rotation start
