INPUT-OUTPUT RELATIONSHIP EXAMPLES
• FS
-FS stands for -15 % of the input range, which is configured by ITEM22, 0 % input voltage and ITEM23, 100 % input voltage.
+FS stands for +115 % of the input range.
• OVF
When one of the following conditions is true, the digital output overflows (OVF).
1) When the input signal is out of the range between -FS and +FS.
2) When the display value (= output signal) exceeds the display range.
The display range differs according to output code. For example, in case of BCD with polarity, it is -9999 to 9999. Please refer
to the table in the FRONT PANEL CONFIGURATION & PROGRAMMING for detail.
