Analog input and output parameter group 02
PARAMETER DESCRIPTION 133
5.3.8 Terminal HDI signal selection and processing
The selection and processing of HDI input are only applicable to digital input HDI terminals, and other digital input
terminals cannot be set as HDI functions.

Terminal HDI selection and processing
“HDI filter time” 02-38(P.526) is used to filter out the vibration of operation frequency caused by factors such as
component precision or noise. The larger the set value of 02-38(
P.526
), the better the filtering ability, but in the
meantime it will also cause response to be slower.
Note:
The calculation method of HDI input signal frequency is similar to 2-5 analog input, and the calculation formula is
01-00(P.1) * ((Input frequency– 02-39(P.524)) *(02-42(P.523) - 02-41(P.522))/ (02-40(P.525) - 02-39(P.524))
+02-41(P.522)).
