Analog Input Units
Section 5-4
for ladder programming in the Master to perform math operations. The follow-
ing two methods of input scaling can be used.
Default Scaling
Analog input values (count values) are converted to the original voltage and
current values. The units used are mV or
μ
A. When default scaling is
selected, scaling is performed according to the range used, as shown in the
following table.
User Scaling
Analog input values (count values) are scaled to user-defined values. The
conversion values for 100% and 0% are set using the Setting Tool.
Note
Reverse scaling, where the 0% scaling value is higher than the 100% scaling
value, is also supported.
Offset Compensation
Scaling analog input values of Linear Sensors to distances produces mount-
ing error in the Sensor. Offset compensation compensates for error that
occurs during scaling. The offset amount is added to the scaled line before
processing, as shown in the following diagram. The offset (error) value can be
input between
–
28,000 to 28,000, but make sure that underflow or overflow
does not occur. The High Limit is 7FFE hex and the Low Limit is 8000 hex.
Note
The offset value can be set even when using default scaling.
