3. Input Method Selection
The inverter 1CN 12-bit digital reference and 6CN sequence input signal
can be input with 0V common, +24V common, or external common. The
wiring differs according to the input method used. For external common,
use +24V (20 to 26V) power supply for input signal.
Common connections are possible because the 1CN and 6CN common
lines are insulated.
