This is a function to adjust an offset error between the connected analog
output device and this analog input unit.
Shift the reference point by a set reference point adjustment value.
- Address writer (ARW-04, ARW-03): Parameter 02
Variable
Reference point shift mode
0
Reference point shift mode OFF
Every time 0 is rewritten to 1, a reference point is adjusted to a
1
device being connected at the time and renewed to a new one.
Reference point shift mode ON
2
A reference point is xed to a point set with the variable 1 and
conversion operation starts.
When "address/parameter automatic setting" is used, the extension unit
follows only ON/OFF of the reference shift mode.
Renew the reference point for each unit.
When the value of the parameter 2 is rewritten from 0 to 1, the 7-segment
display in the reference point shift mode indicates input speci cations set at
the parameter 1.

The average result of 32 times of voltage or current values input at this time
becomes the reference point adjustment value.
For AnyWireLink transmission, "measurement value - reference point
adjustment value" is stored as input data.
When the value of the parameter 2 is renewed to 1, the reference point shift
mode is turned ON.
While the value of the parameter 2 is 1, "CHG" and "Pr2" is alternately
displayed for 7-segment display.

■Display example during operation
When receiving the transmission signal and starting, the unit displays set
input speci cations for about 3 seconds and then switches them to actual
input value display.
Ex.) When setting to 4-20 mA speci cation and operating
