3.6.3

Setting the frequency by analog input (voltage input)

POINT
· To give a start command, terminal between SD and STF (STR) is turned ON.
· Frequency command is given from the potentiometer (by connecting terminal 2 and 5).
[Connection diagram]
(The inverter supplies 5V of power to frequency setting potentiometer. (Terminal 10))
Operation example Performing operation at 60Hz.
Operation
1.

The monitor display appears.
2.
Start
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
Turn the potentiometer (frequency setting
potentiometer) clockwise slowly to full.
The frequency on the indication increases by the Pr.7
Acceleration time, and "
[FWD] indication is lit during forward rotation, and
[REV] indication is lit during reverse rotation.
4.
Deceleration
Turn the potentiometer (frequency setting
potentiometer) counterclockwise slowly to full.
The frequency on the indication decreases by the
Pr. 8 Deceleration time, and the motor stops rotating
with " " (0.00Hz) displayed on the indication.
[FWD] indication or [EXT] indication flickers.
5.
Stop
Turn the start switch (STF or STR) off.
[FWD] indication or [REV] indication turns OFF.
