:Optional RP pulse input
:Optional high-speed pulse input
Note 1: About the setting of and: Do not select the same terminal that is used feedback
terminal.
Note 2: The voltage/current changeover of the analog input VI/II and the option AI1 can be set by the parameter
 or 
Note 3: The reaching signal of the feedback value and the process value can be output.
The desired feedback input should be assigned to the unoccupied output terminal.
The detection width for reaching can be set by the parameter 
