The setting method of the scaling values is explained below. Refer to 6-1 Scaling
Value Teaching for the method to obtain the scaling values from the teaching
operation.
Scales input values into desired values within a range from –9999 to 9999. X2 –
Y2 and X1 – Y1 must be input (X: input value, Y: corresponding display data).
The X1 value must be different from the X2 value, otherwise the Unit will process
them as an overrange value of B000.
The following are the factory-set scaling values.
X1: 0
X2: 1000
Y1: 0
Y2: 1000
Therefore, if the Unit is operated with the factory-set scaling values with an input
range from 4 to 20 mA, an input of 4 mA will be regarded as 400 and an input of
20 mA will be regarded as 2000. When the input type is "1 to 5 V," an input of 1 V
will be 1000 and that of 5V will be 5000. When the input type is "–9999 to 9999 V,"
an input of 9,999 V will be 9999 and that of –9999 V will be –9999.
The graph below shows the relationship between the actual input values and the
internal data.
