Analog Reference Cards
When using a AI-14B or A1-14U analog reference card, set parameter b1-01 (Reference selection) to 3
(Option Card).
The AI-14B provides 3 bi-polar input channels with 14-bit (plus sign) A/D conversion.
If b1-01 is set to 1 and F2-01 is set to 0, the channel 1 and 2 replace the analog inputs A1 and A2. A1 becomes
the frequency reference input and the function of A2 can be selected using parameter H3-09. In this case no
digital input can be set for the Option/Inverter selection function (H1- = 2).
If b1-02 is set to 3 and F2-01 is set to 1, the sum of three input channels becomes the frequency reference
value.
The AI-14U provides 2 unipolar inputs channels with 14-bit A/D conversion. Channel 1 is a voltage input and
channel 2 is a current input. The sum of the channels 1 and 2 is the frequency reference. F2-01 does not need
to be set for the AI-14U option card.

Digital Reference Cards
When using a DI-08 or DI-16H2 Digital Reference Card, set b1-01 (Reference selection) to 3 (Option Card).
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.
