8-4 Overview of the Analog Output Slave
Unit
An Analog Output Slave Unit converts (DA conversion) digital data (binary value) stored in the
EtherCAT Master Unit to analog signals such as 1 to 5 V and 4 to 20 mA and output them.
Digital data that is output is converted to analog data using a set output range as shown below.
If the output data exceeds the data range for which conversion is possible, the converted data is fixed at
the maximum or minimum value of the range.
 Output range 0 to 5 V
Data from 0000 to 1F40 hex (0 to 8000) is converted to voltage from 0 to 5 V and output.
The output data range for which conversion is possible is FE70 to 20D0 hex (−400 to +8400) and
here the output data is −0.25 to +5.25 V.
 Output range 1 to 5 V
Data from 0000 to 1F40 hex (0 to 8000) is converted to voltage from 1 to 5 V and output.
The output data range for which conversion is possible is FE70 to 20D0 hex (−400 to +8400) and
here the output data is 0.8 to 5.2 V.
