Setting Precautions
Always set b1-01 (Reference selection) to 1 (control circuit terminal) when using the AI-14B for three chan-
nels of independent inputs. When this is done, H1-01 to H1-06 (multi-function contact inputs) cannot be set to
2 (Option/Inverter selection).
Using a Digital Reference Board (SPEC: E or Later Only)
When using a DI-08 or DI-16H2 Digital Reference Board, set b1-01 (Reference selection) to 3 (Option
Board).
The DI-16H2 can be used to set a frequency using a 16-bit digital reference. The DI-08 can be used to set a
frequency using a 8-bit digital reference.

the AI-14B Analog Reference
Board is used.
0: 3-channel individual (Chan-

terminal A3)
1: 3-channel addition (Addition

erence)
When set to 0, select 1 for b1-
