Appendix 1-2 Offset/Gain Adjustment of Analog Output Module
<Offset/gain adjustment>
In this mode, offset value and/or gain value can finely be adjusted for individual channel.
Offset value: Means the lower limit value of the range span. When this value is adjusted, the conversion characteristic
curve moves parallel in vertical direction.
Gain value: Means the upper limit value of the range span. When this value is adjusted, only gain value is changed while
offset value is kept unchanged.
When offset and gain values are changed by scaling, the values that are set by scaling take effect as offset and gain values.
When offset and/or gain values are to be adjusted after scaling, adjust by the values of scaling.
Note 1: Offset/gain adjustable range is within 1% of range span. It takes approximately 2 minutes to adjust from 0% to 1%.
If adjustment is made using an analog value that exceeds the adjustable range (if the value is input to a terminal of
the module), the value is limited to 1% of range span.
Note 2: If range is changed, offset and gain return to the default values.
Note 3: The current output modules cannot output negative current value.
