To configure these two inputs AI1 and AI2, take the following steps:
Step 1: Select the input mode
Set [E1.35] to select the input mode of AI1 and [E1.40] to select the input mode
of AI2.
Step 2: Set the channel gain and filter time
[E1.38] is for AI1 gain and [E1.43] is for AI2 gain.
Parameter [E1.69] is used to define the analog channel filtering time constant
for processing of input signals. Longer filtering time means stronger anti-inter-
ference capability and slower response; shorter filtering time means weaker an-
ti-interference capability and faster response.
Step 3: Select input curve
There are two analog input curves that can be selected by [E1.68], AI1 and AI2
inputs can use both curve 1 and curve 2.
