16 When you turn on the external switch, the motor
starts running.
In the main area of the [Standard mode] screen,
the output frequency is displayed.
The motor accelerates according to the setting of
<ACC: Acceleration time 1>, and its frequency
changes to the frequency command value set with
<FC: Panel run frequency> and becomes stable.
In the example on the right, it is 30.0 Hz.
The following are always displayed in the status
area on the upper side of the screen regardless of display mode. (From the left)
• The icon is rotating
• Operation status "RUN"
• Frequency command (display contents vary depending on the setting of the parameter)
• Run command icon
17 To stop the motor, turn off the external switch.
The motor decelerates according to <dEC: Deceleration time 1> and stops.
4. 4. 2 [Operation example 2] Setting frequency with
external potentiometer/analog signal
Input both run command and frequency command externally.
Set the frequency command with a potentiometer connected to outside or a voltage/current signal from
outside.
• First, check connection from external contacts such as switch/relays to the control terminal.
Here is a case where run/stop is input with a switch and a frequency command is input with a
potentiometer (1 - 10 k
Ω , 1/4 W) or voltage (0 - 10 Vdc, -10 to +10 Vdc).
• Next, make setting so that a run command and a frequency command can be input externally
(terminal).
• After setting the above, operate the motor by using the external switch/potentiometer or voltage
signal.
• The parameters to be set are <CMOd: Run command select> and <FMOd: Frequency command
select 1>.
• Control connection is explained in the case of sink logic.
Memo
• Reverse run of the motor can be performed by connecting an external contact (switch/relay,
etc.) between the terminal [R] and terminal [CC] similarly to the procedure above. For details,
refer to [Chapter 7].
