Setting The Frequency By Analog Input (Current Input) - Mitsubishi Electric F700 Instruction Manual

3.6.5

Setting the frequency by analog input (current input)

POINT
· Switch terminal STF(STR)-SD on to give a start command.
· Turn the AU signal on.
· Set "2" (External operation mode) in Pr. 79 Operation mode selection
[Connection diagram]
1.
Screen at powering on
The monitor display appears.
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.
CAUTION
When both of STF and STR signals are turned
ON, the inverter cannot start.
If both are turned ON while the inverter is
running, the inverter decelerates to a stop.
3.
Acceleration → constant speed
Perform 20mA input.
The frequency on the indication increases by
the Pr.7 Acceleration time, and "
(60.00Hz) appears.
[FWD] indication is lit during forward rotation,
and [REV] indication is lit during reverse rotation.
4.
Deceleration
Input 4mA or less.
The frequency on the indication decreases
by the Pr. 8 Deceleration time, and the motor stops
rotating with "
indication.
[FWD] indication or [EXT] indication flickers.
5.
Stop
Turn the start switch (STF or STR) off.
[FWD] indication or [REV] indication turns OFF.
REMARKS
Pr. 184 AU terminal function selection must be set to "4" (AU signal) (initial value). (Refer to the chapter 4 of
(applied).)
