 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 SW6.

You can select terminal functions
using the parameter settings corre-
Input sponding to each terminal. You can
terminal switch between the sink logic and
source logic by switching SINK/SRC
of SW6.
Pulse When [CA-90] is set to 00, A, and B
input-A terminals can be used as input termi-
nals.
You can select terminal functions

input-B
When [CA-90] is not set to 00, they
are used as terminals for pulse string
input.
The maximum input pulse is 32kpps.
