4.3 Basic operation procedure (External operation)
Select a method to give the frequency command from the list below, and refer to the specified page for its procedure.
4.3.1 Using the frequency set by the operation panel
• Switch ON the STF (STR) signal to give a start command.
• Use the operation panel ( ) to give a start command.
•Set Pr.79 ="3" (External/PU combined operation mode 1).
[Connection diagram]
The following shows the procedure to operate at 30 Hz.
1. Changing the operation mode
Set "3" in Pr.79. [PU+E] indicator is on.
2. Setting the frequency
Turn to until the target frequency, "30.00 Hz", appears.
Press [SET] to enter the frequency. "Completed" flickers.
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.
