Refer to the followings for 04-00 AI input signal type:
If AI1 is 0~10V, set parameter 04-00 to 0 or 1.
If AI1 is -10~10V, set parameter 04-00 to 2 or 3.
If AI2 is 0~10V, set parameter 04-00 to 0 or 2 and tune SW2 on the control board to V.
If AI2 is 0~20mA, set parameter 04-00 to 0 or 2 and tune SW2 on the control board to I.
If AI2 is 4~20mA, set parameter 04-00 to 1 or 3, tune SW2 on the control board to I.
If AI2 is 2~10V, set parameter 04-00 to 1 or 3, tune SW2 on the control board to V.
(1) Analog Input Level Adjustment AI1, AI2 (04-02, 04-03, 04-07, 04-08)
Each analog input AI1and AI2 has a separate gain and bias parameter associated with it.
Analog input signal AI1 can be adjusted with parameter 04-02 and 04-03; Analog input signal AI2 can be
adjusted with parameter 04-07 and 04-08. Refer to Figure 4.4.35.
