t terminal
Analog output (1) terminal
In the analog output (1) terminal (AOT1), you can be change 0 to
+/-10 V output and 6F (frequency) output. Its maximum output
current 1 mA.
GND GND
terminal
[Caution] Do not connect the terminal GND to the protective earth
terminal.
AIN1
Analog input (1) terminal
In the analog input terminal (AIN1), you can switch the input range 0
t/-10 V or 0 through 10 V by changing the setting data.
Also, you can switch to 4 to 20 mA input by setting the SW1
(VFC66-Z) to input.
Use 10 k

+10 V output
O10 V direct-current voltage.
ST-F
Forward operation
Input terminal for a Forward operation signal.
PS
+12 V output
O12 V direct-current voltage.

Multifunction input terminal (1)
Maximum input voltage 24 VDC, maximum input current 3 mA.
Like from the concole panel (SET66-Z), you can operate the VF66B
(DC motor draive) by inputting asignal into the multifunction input
terminals.
[Caution] Do not connect the terminal GND to the protective earth
terminal.
* For the details of the multifunction input terminals, refer to
"6.4 Area c" in Chapter 6 and "7.4 Area c" in Chapter 7.

PG output terminal
Generate and output a subharmonic waveform from a signal of the
terminal [A].
The [3] of SW4 sides are 1 / 4PG dividing signal output, and the [1]
sides are 1 / 2PG dividing signal output.
