• If a linear input is used and the decimal position is 1, then the range for the
parameter is reduced to –199.9 to 999.9.
• If a linear input is used and the decimal position is 2, then the range is –19.99 to
99.99.
• If a linear input is used and the decimal position is 3 (the maximum for linear inputs),
then the range is –1.999 to 9.999.
In contrast, when a thermocouple or RTD input is used, the decimal position specified
using the dEC.pdEC.p parameter in the dSLPdSLP (display) menu is a maximum. This means that
the controller applies the specified number of decimal places only if doing so does not
limit the value of the parameter. For example, suppose the range of valid values for a
parameter is –1999 to 9999.
• If an RTD or thermocouple input is used and the decimal position is 1, then the range
for the parameter is still –1999 to 9999. If you configure a value of 1000, no decimal
places will be displayed, despite the Decimal Position setting of 1.
• If an RTD or thermocouple input is used and the decimal position is 2 (the maximum
for temperature inputs), then the range for the parameter is still –1999 to 9999. If you
configure a value of 1000, no decimal places will be displayed, despite the decimal
position setting of 2.
