Theanalog input unit Ver.1.2 or after are equivalent to approx. 0 V.(Note 3): The time shown in the figure below is required to reflect analog input values in the input device area (WX)read by the control unit. The following figure shows the values when the range of -10 to +10 V is used.(Note 4): Installed in the unit of Ver.1.2 and after (only 12-bit mode)
