8-2 Overview of the Analog Input Slave
Unit
Analog Input Slave Unit convert (AD conversion) analog input signals such as 1 to 5 V and 4 to 20 mA
to digital data (binary values) and store them in the EtherCAT Master Unit.
Input analog signals are converted to digital data in the following manner using a set input range.
If the input data exceeds the data range for which conversion is possible, the converted data is fixed to
the maximum or minimum value of the range.
 Input range 0 to 5 V
Voltage of 0 to 5 V is converted to data from 0000 to 1F40 hex (0 to 8000). The input data range for
which conversion is possible is −0.25 to 5.25 V and here the output data is FE70 to 20D0 hex (−400
to 8400). When input data is a negative voltage, it is expressed as the two's complement
(hexadecimal) and the output data for a disconnected line is the same as for an input of 0 V (0000
hex).
