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. 
 
 
Figure 4.4.35 Analog inputs and related parameters 
 
Gain setting: Sets the level in % that corresponds to a 10V, -10V or 20mA signal at the analog input. 
(Set the maximum output frequency 01-02 to 100 %)     
Bias setting: Sets the level in % that corresponds to a 0V or 4mA signal at the analog input. 
(Set the maximum output frequency 01-02 to 100%) 
 
Use both gain and bias setting to scale the input signal.
