4-1-4 Decimal point
▪ Determine decimal point place.
▪ When IN-T is one of TC, RTD group, IN.DP will skip.
▪ Decimal point place can be adjusted with IN.DP parameter when IN-T is one of DCV, mV.

Precaution on changing decimal point
▪ Changing IN.DP, the decimal point of other parameters as well as PV will be changed.
The affected parameters are SP, Alarm, Event, Deviation related parameters.
4-1-5 PV display range
▪ Set the high and low limits of the scaled data of the input.
▪ TC, RTD : IN.SH, IN.SL will not appear.
▪ DCV, mV : The input signal is scaled with IN.SH and IN.SL value.
(100％ input is scaled to IN.SH and 0％ input is scaled to IN.SL with linear transformation)

Setting Example
▪ Input type is DCV and the range is 1~5V and scaled display need to be 0~100
IN-T : 5V
IN.SH : 100 (5V input is scaled to “100” display)
IN.SL : 0 (1V input is scaled to “0” display)
4-1-6 Input filter (IN.FL)
▪ When the noise level of the input signal is high, input filter reduces the effect of the noise.
▪ When PV fluctuation is significant, control is unstable, or PV ripples due to some vibration, the
change rate of PV decreases with increasing the filter value.
