Control circuit
■Input terminals
• All COM terminals are at the same potential.
• When connecting a power supply between 1-9, A, B and COM, switch SW5 to the external power
supply (EX).
• You can switch between the sink/source logic of input terminals by using SW6.
(Wiring example)
• Indicates the factory default setting.

You can select terminal functions
using the parameter settings corre-
sponding to each terminal. You can
switch between the sink logic and
source logic by switching SINK/SRC
of SW6.
