Analog Input Parameters (I/O-40 through I/O-71)
Low/High Parameters Pro-
cess and Input Value
The Process and Input Value Low/High parameters define the scaling for each of the An-
alog Inputs.
The “Input” parameters describe the electrical signal going into the analog input. If it is a
4-20mA type analog input, the units are in milliamps. If it is a 0-10V or -10 to 10V type
analog input, the units are in volts.
The “Process” parameters describe what that electrical signal is translated to. These pa-
rameters are entered as a percentage of the full scale process variable. The process var-
iable is determined by the Analog Input Function selection.
For example, if Speed Reference is selected for the Analog Input Function, then the pro-
cess variable is percentage of the Maximum Frequency parameter (DRIVE-10).
For scaling to the fullest, set Process Low to 0% and Process High to 100%, then set In-
put Low to the minimum electrical signal, and Input High to the maximum electrical sig-
nal.
For scaling to a different gain, or to incorporate an offset, adjust these four parameters as
necessary.
