Set Parameter 314, Terminal 60, Analog Input
Current, to correspond to the purpose of the 4 to
20 mA signal.
Set Parameter 315, Terminal 60, Min. Scaling, to 4 mA.
Set Parameter 316, Terminal 60, Max. Scaling, to
20 mA.
Because the commons of the +24 VDC power
supply and the input reference follower have
separate circuit commons, it is necessary to
connect a jumper between terminals 39 and 55.
