Setting the frequency by analog input (current input)

POINT
· Use
or
on the operation panel (FR-DU07) to give a start command.
· Use the current signal source (4 to 20mA) (by connecting terminal 4 and 5) to give a frequency command.
· Switch ON the AU signal.
· Set "4" (External/PU combination operation mode 2) in Pr. 79 Operation mode selection.
[Connection diagram]
Operation example Performing operation at 60Hz.
Operation
1. Screen at power-ON
The monitor display appears.
2. Operation mode setting
Set "4" in Pr.79.
[PU] indicator and [EXT] indicator are lit.
(To change the set value, refer to page 48)
3. Start
Check that the terminal 4 input selection signal (AU) is ON.
Press
or
[FWD] or [REV] is flickering as no frequency command is given.
4. Acceleration → constant speed
Perform 20mA input.
The frequency on the display increases in the Pr. 7 Acceleration
time, and "
" (60.00Hz) appears.
5. Deceleration
Input 4mA or less.
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.
6. Stop
Press
[FWD] indicator or [REV] indicator turns OFF.
REMARKS
Pr. 184 AU terminal function selection must be set to "4" (AU signal) (initial value). (Refer to Chapter 4 of
Manual (Applied).)
Change the frequency (60Hz) at the maximum current input (at 20mA, initial value)
Adjust the frequency in Pr. 126 Terminal 4 frequency setting gain frequency. (Refer to page 70.)
Change the frequency (0Hz) at the minimum current input (at 4mA, initial value)
Adjust the frequency in calibration parameter C5 Terminal 4 frequency setting bias frequency. (Refer to
