4.5.5 Setting the frequency by analog input (current input)
[Connection diagram]
POINT
· 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.
REMARKS
Pr. 184 AU terminal function selection must be set to "4" (AU signal) (initial value). (Refer to Chapter 4 of the Instruction Manual
(Applied).)

2.Start
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
command is given.
5.Stop
Turn the start switch (STF or STR) OFF.

Stop
When both of STF and STR signals are turned
ON, the motor cannot start.
If both are turned ON while the motor is
running, the motor decelerates to a stop.
4.Deceleration
Input 4mA or less.
The frequency on the display decreases
in Pr. 8 Deceleration time, and the motor stops
rotating with " " (0.00Hz) displayed.
[FWD] indicator or [EXT] indicator flickers.

Perform 20mA input.
The frequency on the display increases
in Pr.7 Acceleration time, and " "

[FWD] indicator is lit during forward rotation,
and [REV] indicator is lit during reverse rotation.
