You can connect the input terminal and the terminal [CC] (common) to the programmable
controller output (non-logic switch) for control purposes. Use this connecting method for

forward/reverse run, or preset speed operation, etc.
■ Usage example: 3-wire operation (one-push operation)
The use of the 3-wire operation function allows the one-push signal (reset logic signal) to be self-
held during operation. No external sequence circuit is needed.
To perform 3-wire operation, make setting as shown below:
<F110: Always active function 1> = "6: Standby"
<CMOd: Run command select> = "0: Terminal"
<F111: Terminal F function 1> = "2: Fwd run" (default setting)
<F112: Terminal R function 1> = "4: Rev run"(default setting)
Also, assign "50: 3-wire operation hold/stop" ("51" for inversion input) to the input terminal.
The following shows an example for assignment to the terminal [S2].
<F115: Terminal S2 function > = "50"
7. Operating using external signals
• To always enable the functions, assign the functions to <F110: Always active function 1>,
<F127: Always active function 2>, and <F128: Always active function 3>.
