BASIC OPERATION
4.6 Basic operation procedure (External
operation)
POINTPOINT
• Where is the frequency command source?
- The frequency set in the frequency setting mode of the operation panel Refer to 4.6.1. (Refer to page 112.)
- Switches (multi-speed setting) Refer to 4.6.2. (Refer to page 114.)
- Voltage input signals Refer to 4.6.3. (Refer to page 115.)
- Current input signals Refer to 4.6.5. (Refer to page 117.)
4.6.1 Using the frequency set by the operation panel
POINTPOINT
• Switch ON the STF (STR) signal to give a start command.
• Use the operation panel (FR-DU08) ( ) to give a start command.
•Set Pr.79 ="3" (External/PU combined operation mode 1).
[Connection diagram]
Operation example Operate at 30 Hz.
Operation
1.
Changing the operation mode
Set "3" in
Pr.79. [PU] and [EXT] indicators are on. (For setting value change, refer to page 101.)
2.
Setting the frequency
Turn to until the target frequency, " " (30.00 Hz), appears. The frequency flickers for about 5 s.
While the value is flickering, press to enter the frequency. " " and " " flicker alternately. After about 3 s of
flickering, the indication goes back to " " (monitor display).
(If is not pressed, the indication of the value goes back to " " (0.00 Hz) after about 5 s of flickering. In that
case, turn again and set the frequency.)
3.
Start acceleration constant speed
Turn ON the start switch (STF or STR). The frequency value on the indication increases in Pr.7 Acceleration time, and
" " (30.00 Hz) appears. [FWD] indicator is on during the forward rotation, and [REV] indicator is on during the
reverse rotation.
(To change the set frequency, perform the operation in above step 2. The previously set frequency appears.)
4.
Deceleration stop
Turn OFF the start switch (STF or STR). The frequency value on the indication decreases in Pr.8 Deceleration time, and
the motor stops rotating with " " (0.00 Hz) displayed.
