Adjusting Analog Input Signals

Adjusting Analog Frequency References

Using the H3- parameters, the analog input values of terminal A1 or the Channels 1 to 3 of the optional
analog input card AI-14B can be adjusted.

Adjusting Analog Input Signals

The frequency reference can be input from the control circuit terminals using analog voltage. The voltage
level at terminal A1 is 0 to +10V. The analog input channels of the AI-14B option card can be used with 0 to
+10V or -10 to +10V.
The input signal levels can be selected using,
H3-01 for AI-14B CH1
•
H3-04 for AI-14B CH3
•
H3-08 for AI-14B CH2
•
The signals can be adjusted using the parameters:
H3-02 (Gain) and H3-03 (Bias) for Channel 1 of the AI-14B option card
•
H3-06 (Gain) and H3-07 (Bias) for Channel 3 of the AI-14B option card
•
H3-10 (Gain) and H3-11 (Bias) for Channel 2 of the AI-14B option card
•
H3-16 (Gain) and H3-17 (Bias) for analog input A1
•
The gain sets the level of the selected input value if 10V is input, the bias sets the level of the selected input
value if 0V is input.
