Start/stop from the operation panel (PU operation)
5.1.3 Setting the frequency by switches (three-speed setting) (Pr. 4 to Pr. 6)
POINT
y Use the operation panel ( ) to give a start command.
y Switch ON the RH, RM, or RL signal to give a frequency command.
y Set "4" (External/PU combined operation mode 2) in Pr. 79 Operation mode selection.

Operation example Operation at low speed (10Hz)
Operation
1.
Screen at power-ON
The monitor display appears.
2.
Easy operation mode setting
Press and for 0.5s. " " appears, and the [PRM] indicator flickers.
3.
Operation mode selection
Turn until " " appears. [PU] and [PRM] indicators flicker.
4.
Operation mode setting
Press to enter the setting. (Set "4" in Pr. 79.)
" " and " " flicker alternately. [PU] and [EXT] indicators are lit.
5.
Start
Turn ON the low-speed switch (RL).
6.
Acceleration Æ constant speed
Press to start running.
The frequency value on the display increases in Pr. 7 Acceleration time, and " " (10.00Hz) appears.
[RUN] indicator is lit during forward rotation operation and flickers slowly during reverse rotation operation.
7.
Deceleration
Press to stop.
The frequency value on the display decreases in Pr. 8 Deceleration time, and the motor stops rotating with " " (0.00Hz)
displayed.
8.
Stop
Turn OFF the low-speed switch (RL).
REMARKS
y The initial values of the terminals RH, RM, RL are 60Hz, 30Hz, and 10Hz. (Use Pr. 4, Pr. 5 and Pr. 6 to change.)
y In the initial setting, when two or three of multi-speed settings are simultaneously selected, priority is given to the set frequency
of the lower signal.
For example, when the RH and RM signals turn ON, the RM signal (Pr. 5) has a higher priority.
y Maximum of 15-speed operation can be performed. ( Refer to Chapter 4 of the Instruction Manual (Applied).)
